Building a Multi-Vendor, Software-Defined Substation: Lessons From Red Hat’s VPAC Demonstrator - Daniel Schaefer, Red Hat

Wednesday September 16, 2026 10:30 - 11:00 CEST

Seebühne

Grid modernization requires moving beyond proprietary "black boxes" toward open, software-defined substations. This session explores the architecture and lessons learned from building Red Hat’s vPAC (virtualized Protection, Automation, and Control) demonstrator. Aligned with the LF Energy SEAPATH reference design, we share experiences how a single-server setup can host multi-vendor vPAC solutions (by ABB and Euto Energy) in different formats (VM and containers). A key highlight is the coexistence of these critical low-latency workloads with non-critical engineering workstations, running side by side on the same box.

Finally, we share validation results from real-time Hardware-in-the-Loop (HIL) simulations of a medium-voltage substation with 10 bays, proving timely trip responses in our lab environment. Discover how an open, enterprise-grade platform decouples hardware cycles from software innovation to drive grid agility.

The Rise of Software-Defined Charging: Maximizing Hardware Flexibility With EVerest - Marco Möller, Pionix

Wednesday September 16, 2026 10:30 - 11:00 CEST

Waldbühne

The EV charging industry is undergoing a massive transformation, mirroring the broader tech shift toward Software-Defined Vehicles (SDV) and Software-Defined Networking (SDN). Welcome to the era of Software-Defined Charging (SDC).
Historically, charging stations were built using rigid hardware blocks, requiring separate microcontrollers for every new functional domain: from complex protocols (ISO 15118) to load balancing and UI. This fragmented, bare-metal architecture slows innovation, drives up BOM costs, and makes feature updates nearly impossible.

SDC changes the paradigm by decoupling hardware from software. By consolidating high-level logic onto a centralized computing unit, manufacturers can drastically reduce complexity and completely transform the product lifecycle. Instead of deploying static hardware that quickly ages out, SDC enables a continuous software lifecycle via over-the-air updates, keeping field assets relevant for years.

In this talk, we will explore how the open-source EVerest project acts as the operating engine for SDC, enabling the hardware ecosystem to mix-and-match physical components, build flexible satellite systems, and utilize digital twin testing.

Wednesday September 16, 2026 10:30 - 11:15 CEST

Sonnendeck

Remedial Action Optimisation (RAO) is becoming a key operational capability to manage interconnected power systems across Europe. As requirements evolve and implementations mature, there is a growing need for coordination between stakeholders contributing to and relying on shared solutions.
This Birds of a Feather session is an open, collaborative forum around PowSyBl OpenRAO, bringing together developers such as Artelys, TSOs such as RTE, and RCCs such as Coreso to exchange on experiences, ongoing work, and upcoming priorities.
RTE and Artelys will present developments carried out on OpenRAO over the past year and those planned for the next (algorithmic improvements, countertrading within the optimisation core, …), with a focus on alignment with requirements from ongoing projects, notably SWE ROSC for Coreso. The session will also explore connections with related initiatives, including ToOP.
Rather than a one-way presentation, we will focus on interaction: participants will be invited to share plans, challenges, and expectations regarding OpenRAO. The objective is to foster convergence, encourage contributions, and strengthen a shared vision for OpenRAO within the LFE community.

CityLearn for Human-Centered Grid Flexibility - Ava Mohammadi, Eindhoven University of Technology (TU/e)

Wednesday September 16, 2026 11:05 - 11:15 CEST

Waldbühne

As buildings become active participants in the energy transition, understanding flexibility at the building and occupant level is becoming increasingly important for addressing grid congestion challenges. While many energy system models rely on simplified representations, detailed grid-integrated building models can provide deeper insight into how HVAC systems, EV charging, distributed energy resources, and occupant behavior interact with the grid in practice.

This talk presents CityLearn as an open-source platform for studying coordinated energy flexibility strategies across buildings and districts. Recently integrated into the LF Energy community, CityLearn enables researchers and practitioners to explore how building dynamics and occupant-centric control approaches can reveal flexibility potential often overlooked in simplified representations. The session will discuss advanced control strategies for HVAC systems, electrical storage, EV charging, and occupant comfort, together with the importance of connecting detailed building intelligence with broader power grid modeling frameworks to better capture realistic building-grid interactions.

From Code To Models-as-Data: GEMS, a High-Level Language for Energy System Modelling - Thomas Bittar, RTE

Wednesday September 16, 2026 11:05 - 11:35 CEST

Crossover

Energy systems are undergoing rapid transformation as sector coupling intensifies and variable renewable generation grows, creating a pressing need for flexible and transparent modeling tools. While many open-source frameworks offer rich features, extending them with new mathematical models typically requires writing custom software, a barrier for many analysts.

We present GEMS (Generic Energy Systems Modelling Schema), a high-level modelling language designed to make multi-energy system adequacy and planning studies both more expressive and more accessible. GEMS brings model definitions out of the codebase and into simple YAML configuration files, where users describe variables, parameters, and constraints using natural mathematical expressions. These expressions are parsed into abstract syntax trees and automatically expanded into a complete optimization problem. This model-agnostic architecture enables rapid experimentation, lowers development and maintenance costs, and promotes true reusability: adding a new model requires no code, only data. The language is already supported in Antares Simulator and in the Python package GemsPy.

Accelerating Grid Digitalisation With Linux-based SEAPATH and Qualcomm Dragonwing - Jean-Jacques Adragna, Qualcomm & Eloi Bail, Savoir-faire Linux

Wednesday September 16, 2026 11:25 - 11:35 CEST

Seebühne

Utilities are engaged in a massive digitalization journey. A software-defined approach brings elasticity, efficiency and evolution to installations that need to operate and evolve for decades. It also open new use cases, like AI and IoT.

This session shows how LF Energy SEAPATH combined with Dragonwing platforms delivers one common Linux foundation platform running on a diverse ARM-based portfolio, from high-performance IQ9 and IQ8 Series down to low-power platforms.

A key enabler is the mainline upstream strategy: support in the Linux kernel and surrounding projects and preliminary support is already available in the SEAPATH GitHub repository. This can improve integration cost and provides a sustainable path for timely security updates aligned with NIS2 and IEC 62443.

The talk focuses on the capabilities utilities need first: real-time determinism, bounded network latency for IEC 61850 SV/GOOSE and PTP time synchronization. Dragonwing also unlocks LTE/5G connectivity (including utility bands 450 MHz) and AI at the edge with NPU for anomaly detection to LLM-based operator assistants.

TopRAO: Real-Time Combined Remedial Actions Optimization With ToOp and OpenRAO - Nico Westerbeck, 50Hertz Transmission GmbH & Peter Mitri, RTE (Réseau de Transport d'Electricité)

Wednesday September 16, 2026 11:25 - 12:10 CEST

Elektro Stage

Operating highly loaded grids in real time requires combining powerful topology optimisation with efficient handling of “linear” remedial actions. ToOp, developed by 50Hertz, is a state-of-the-art optimiser for topological measures, going beyond the topology optimisation currently available in OpenRAO.

In TopRAO, we couple ToOp with the Powsybl-based OpenRAO toolbox: OpenRAO optimises linear remedial actions (PST, redispatching, counter-trading, HVDC), while ToOp focuses on topological measures. Together, they form a real-time-capable RAO engine for security analysis at TSO and inter-TSO level.

This demo walks through an end-to-end workflow: importing network data, running joint optimization of topology and linear actions, and analysing resulting constraints, actions and costs using open, transparent components.

One Measurement Layer, Many Virtual Substation Functions: RTE and EcoPhi’s 400/225 KV Digital Substa - Ebrahim Balouji, EcoPhi

Wednesday September 16, 2026 11:40 - 12:10 CEST

Seebühne

Transmission substations are expected to host more monitoring functions, but each one adds hardware, wiring, panel space, engineering effort and lifecycle cost. In EcoPhi’s 400/225 kV digital substation project with RTE, the approach is one measurement layer supporting multiple virtualized applications.

EcoPhi’s QMU 800 acts as the digital measurement layer, sampling voltage and current signals at up to 2 MHz. The setup follows IEC 61869, allowing substation signals to be digitized once and reused by software applications. EcoPhi’s CMPC 800 provides the edge platform where applications run in a virtualized environment using SEAPATH.

This enables PQ monitoring, PMU/synchrophasor functions, PD monitoring, digital fault recording and digital fault location to run as virtualized applications instead of separate devices. By decoupling measurement from applications, the system reduces hardware duplication, panel complexity, copper wiring, installation, commissioning, maintenance and lifecycle cost.

The presentation will describe the RTE architecture, IEC 61869 setup, roles of QMU 800 and CMPC 800, and lessons from preparing a transmission-grade virtualized substation.

The Next Generation of Intelligent HEMS: A Self-Evolving Perspective - Rui Li & Xiaoke Yang, EcoFlow Inc.

Wednesday September 16, 2026 11:40 - 12:10 CEST

Waldbühne

Home Energy Management Systems (HEMS) increasingly operate in non-stationary conditions: changing tariffs, evolving household behavior, new DER assets, and fragmented device ecosystems. Most current deployments still rely on static rules and periodically retrained models, which degrade under drift and are hard to maintain at scale.

This session presents a self-evolving HEMS architecture that closes the loop across three core tasks:
(1) classification for safety/reliability monitoring,
(2) regression for PV/load forecasting, and
(3) optimization that converts natural-language user goals into executable schedules.

An LLM-centered orchestration layer coordinates rule engines, ML models, user/context memory, and control APIs to support transparent interaction, adaptive decision-making, and continuous improvement. We share field-oriented case studies showing improved robustness in detection, better forecasting performance, and practical end-to-end scheduling execution.

The talk focuses on reusable architectural patterns and deployment lessons relevant to open, software-defined energy systems.

CIM/CGMES in Real-time Knowledge Graphs for Modern Grid Control Systems - Arne Bernhardt, SOPTIM AG

Wednesday September 16, 2026 11:40 - 12:10 CEST

Crossover

Modern grid control systems require interoperable, scalable, and vendor-neutral data infrastructures. While CIM/CGMES has become the standard exchange format for power system models, many implementations still treat it primarily as a file format instead of a semantic data platform.

This session presents practical experiences from building modern utility control system components using RDF, SHACL, SPARQL, Apache Jena, and open-source tooling. We will show how semantic technologies can evolve from offline model exchange into high-performance, real-time knowledge graph infrastructures for power systems.

Topics include high-performance in-memory RDF graph processing, SHACL validation for operational grid models, lessons learned from Apache Jena internals, and the development of open-source tooling such as RDFArchitect and OpenCGMES.

The session shares real-world insights from developing software for transmission system operators and discusses how open semantic infrastructures can support interoperable and future-proof digital energy systems.

Open Substation: Building an Open Stack for Digital Substations - Guillaume Tucker, gtucker.io

Wednesday September 16, 2026 13:10 - 13:20 CEST

Seebühne

Open Substation is an informal, community-driven initiative to provide a full open-source software stack for Digital Substations. It is currently based on a handful of initial projects including SEAPATH (hypervisor) and OpenEnergyTools (IEC61850 implementation) with the aim to grow over time via new individual contributors and organisations.

Electrical equipment vendors all have access to labs and facilities that enable them to deploy production-grade virtual protection functions in real grids. However, these typically rely on key proprietary components and as such it's difficult for the general public to engage in an open-source way: academics, startups, enthusiasts...

In this lightning talk, we'll go through the steps that first led to the creation of Open Substation, how it's filling the gaps in the stack and most importantly, how you can take part.

LF Energy Smart HEMS-Benchmark Demo - Jawen Zhang & Edison Tuo, EcoFlow Inc.

Wednesday September 16, 2026 13:10 - 13:55 CEST

Elektro Stage

This demo introduces Smart HEMS-Benchmark, an open benchmarking framework for residential DER systems that is entering the LF Energy project onboarding process. It addresses a key gap in today’s ecosystem: the lack of transparent, standardized, and reproducible evaluation for HEMS performance across technologies, regions, and policy settings.
We demonstrate an end-to-end workflow across three layers: (1) location and sizing assessment with long-horizon techno-economic analysis, (2) HEMS algorithm benchmarking under standardized scenarios, and (3) VPP participation benchmarking for grid-service and market-oriented use cases. The demo covers uncertainty-aware simulation (load, PV, price, device behavior), multiple tariff models (fixed, TOU, dynamic), and policy regimes (e.g., net metering, net billing, non-export).
By combining open datasets, consistent metrics, and repeatable pipelines, Smart HEMS-Benchmark enables fair comparison from baseline strategies to advanced AI-driven control, supporting both research and real-world deployment decisions.

Build With OpenGridFM: Synthetic Grid Data and Graph Neural Solvers in Practice - Alban Puech, IBM Research - Zurich

Wednesday September 16, 2026 13:10 - 14:50 CEST

Back Stage

This hands-on tutorial introduces our end-to-end framework released through the OpenGridFM project, enabling the development and deployment of GridFM models for steady-state grid analysis.
Participants will work with notebooks to generate synthetic but realistic power-flow and optimal-power-flow datasets using gridfm-datakit, including load variation, generator-dispatch variation, topology perturbations, and configurable grid cases. They will then use gridfm-graphkit to train and evaluate GENCO, a unified graph neural solver, in a low-code environment and compare its performance against classical solvers. For advanced participants, the tutorial will also explain how to implement, integrate, and benchmark custom model architectures using the framework and the provided benchmarking datasets.
The tutorial is designed for power-system practitioners, researchers, and developers who want to contribute to OpenGridFM or apply its tools in their own workflows. No prior experience with the project is required; familiarity with Python and basic power-system concepts is helpful.

Automated Checks Before Publishing Open Source, a Few Years Later - Nico Rikken & Leander van der Bijl, Alliander

Wednesday September 16, 2026 13:20 - 13:30 CEST

Seebühne

At the LF Energy Summit of 2024, Alliander’s OSPO team presented their internal process for preparing projects to be released as open source. One presentation highlighted the tooling and automation in place to review the codebase prior to open sourcing.

After two years of working with this setup, Alliander is improving the automation approach based on the lessons learned during this period. In this presentation, the team of Alliander will share the new insights, the planned improvements and the progress made so far:

Teams now run the pipeline themselves, rather than the OSPO. This required the policies to change to reduce the number of false-positives that would cause confusion. Ideally the automation could be run on the developer laptop and as an open source pipeline on pull-requests after becoming open source. In the meantime Repolinter is no longer maintained, raising the question for revival or replacement. License review of dependencies still requires expertise of the OSPO given the number of false-positives.

The OSPO SIG is the place to continue knowledge sharing and collaboration on this topic in the LF Energy community.

Bridging the Gap: Advancing PyPSA as an Industry-Grade Open Energy Planning Framework - Fabian Hofmann, Open Energy Transition

Wednesday September 16, 2026 13:30 - 13:40 CEST

Seebühne

Open-source energy models are becoming increasingly important for transparent and reproducible energy planning. At the same time, many institutions still rely on proprietary software for day-to-day planning and decision-making. Closing this gap requires more than open code. Open-source tools also need the functionality, reliability, and long-term support expected by industry users.

This session presents the PyPSA-Taskforce, a joint initiative by Technische Universität Berlin, Università di Pisa, and Open Energy Transition to strengthen PyPSA as a professional open-source tool for energy system planning. The Taskforce focuses on improving areas of PyPSA that are still missing or not yet mature enough for wider industry adoption.

The project focuses on developing and integrating capabilities needed for real-world planning applications while maintaining the transparency and flexibility that make open-source tools valuable. At the same time, it aims to move beyond the limitations of proprietary software by building a tool that can evolve openly with the needs of the energy transition.

OpenEnergyTwin: Building Open, Interoperable Digital Twin Infrastructure for DSO Grid Operations - Jürgen Meister, OFFIS – Institute for Information Technology

Wednesday September 16, 2026 13:45 - 14:15 CEST

Crossover

Distribution system operators (DSOs) must manage increasingly complex grids with renewable generation, electrification, sector coupling, and active assets, especially at the low voltage level. Today’s grid control systems, however, are often monolithic, proprietary, and hard to extend, limiting interoperability and innovation. OpenEnergyTwin addresses this issue as an open source reference implementation for modular grid control systems. It provides a modular, event-driven digital twin infrastructure, capable of integrating all grid levels of a DSO, thereby creating a runtime environment for next-generation grid control services, including AI-based assistance and automation. The platform connects operational technology to a CIM-based digital twin core through flexible protocol adapters for topology, measurements, and state assessment, and exposes standardized interfaces for HMIs, alerting, forecasting, and control applications. Using publish-subscribe communication and CIM/JSON-LD, OpenEnergyTwin enables event-driven, standardized data exchange across all services. This talk presents key results of the research project, in which the OpenEnergyTwin platform has been developed.

Dynaωo for Large-Scale Power System Event Analysis: The 2025 Iberian Blackout - Marco Chiaramello; Gilles Aouizerate, Joy El Feghali & Florentine Rosiere, RTE

Wednesday September 16, 2026 13:45 - 14:15 CEST

Waldbühne

On 28 April 2025, continental Spain and Portugal experienced a total blackout, while the rest of the European grid was largely unaffected. This most severe European blackout in over 20 years is analysed using a time-domain model of the Iberian system derived from an anonymised network snapshot. In its final report on the incident, ENTSO-E’s Expert Panel identifies LF Energy’s Dynaωo, an open-source, industrial-grade suite of simulation tools, as the basis for its independent voltage stability study. Simulations closely reproduce recorded measurements and clarify the roles of cross-border exchanges, TSO-DSO interactions, distributed renewable energy sources and limited reactive power margins in the voltage rise that triggered the cascade. The study highlights the value of relying on an open-source industrial tool and shows how Dynaωo has evolved into a robust, high-performance solution. The presentation will detail the modelling and simulation approach, key challenges, and the main insights gained on the 28 April 2025 events, demonstrating how Dynaωo delivers the level of transparency, reproducibility and scientific rigour now expected for the analysis of major power system events.

Mastering the Grid: How MCP & AI Make Power System Simulations Effortless - Jérôme Picault, RTE (Réseau de Transport d'Electricité)

Wednesday September 16, 2026 14:05 - 14:50 CEST

Elektro Stage

Executing grid modelling and simulations like load flows, N-1 analyses, or sensitivity studies typically demands deep tooling expertise or custom scripting. What if grid engineers could drive these workflows directly in natural language - without sacrificing rigor or control?

pypowsybl-mcp demonstrates an open-source Model Context Protocol (MCP) server that exposes PowSyBl as AI-callable tools, callable by any conversational UI or AI agent to perform grid modelling simulations.

Our demo showcases a comprehensive TSO workflow driven entirely by natural-language prompts. Attendees will watch our AI agent dynamically orchestrate complex tool calls to execute:
1. Stress assessment: "Run an AC load flow; show voltage violations"
2. N-1 security: "Run N-1 on 400 kV lines; identify insecure contingencies"
3. Sensitivity: "Rank generators by impact on overload mitigation"
4. Remedial action: "Re-dispatch and re-run N-1"
5. Reproducibility: "Generate a Python script to reproduce this session"
Results come from pypowsybl (accurate, reproducible, hallucination-free results), while the LLM handles orchestration only and adaptation of results to the expertise of the user.

How Grid Operators Can Unlock Asset Flexibility - Integrating FlexMeasures + OpenLEADR Via OpenADR - Nicolas Höning, Seita Energy Flexibility & Nick van der Burgt, ElaadNL

Wednesday September 16, 2026 14:20 - 14:50 CEST

Seebühne

OpenADR is a protocol to connect the grid to smart energy. Utilities send events to EMS & aggregators, who adapt scheduling for their flexible assets to improve thr local grid situation.

In this session, we bring OpenADR to an actionable implementation, fully based on open-source software (two LF Energy projects, in fact!). We present a new plugin to the Cloud EMS FlexMeasures, which enables FlexMeasures sites to receive OpenADR events (acting as an Virtual End Node or "VEN", in OpenADR terms). OpenLEADR is used to add such signals from the utility side (acting as a Virtual Top Node, or "VTN").

The use case we present in this session is that a utility sends congested time slots on a daily basis to charge point operators in its network. This use case is currently being piloted in the Netherlands with OpenADR.
We will show how utilities can enter and broadcast these congestion signals with OpenLEADR. The CPOs will take these dynamic limits into account in their optimized charge scheduling. We'll show how an existing behind-the-meter orchestration is built in FlexMeasures (where much more than "just" EV charging can be modelled), and how the new event will influence this planning.

Presenting DyCoV - Streamlining Dynamic Model-validation and Performance Verification Using Dynawo - Jose Luis Marin, AIA

Wednesday September 16, 2026 14:20 - 14:50 CEST

Waldbühne

DyCoV (Dynamic Compliance Verification) is an Open-Source tool built by RTE for bringing transparency to the process of verifying grid-code compliance of the dynamic behavior of new generation facilities. It contemplates both *electric performance* (i.e., "does the behavior pass the requirements?") and *generic model validation* (i.e., "does the model match the actual behavior?").

The tool builds upon Dynawo, RTE's Open-Source dynamic simulator, which in turn uses Open Modelica for its RMS models, including WECC and IEC generic models. This provides a fully transparent process for all stakeholders, thus avoiding the pitfalls of proprietary models and black-box tools. In addition, DyCoV removes the drudgery of measuring, comparing, and extracting all required KPIs from curves: rise/settling times, FRT responses, point-wise diffs, etc.

The tool is built with Python and structured as a series of independent tests, each producing its own report in PDF. The current tests correspond to RTE's connection grid code (DTR document), but DyCoV design uses templating (Jinja) and configuration files to make it easily adaptable to other grid codes, avoiding code changes as much as possible.

Batch N‑1 Power Flow Via Perturbation Methods - Georg Mensah, 50 Hertz/ Elia Group

Wednesday September 16, 2026 15:20 - 15:50 CEST

Waldbühne

Modern AI for power flow and OPF is on the rise, but it will still require large amounts of trustworthy training data and strong conventional solvers for validation (“solver‑certified AI”). An important application are adjacent‑state studies needed for N‑1 screening and decision planning. This session argues that classic algorithms will not vanish, but must be redesigned for batch computation: solving many related grid states faster than repeated Newton-style runs. We reshape ideas from perturbation theory into a load-flow solver pattern that reuses structure across scenarios and maps well to parallelizable hardware. We introduce the key mathematics behind the approaches including the holomorphic embedding load flow method (HELM) and related methods. We then show how to turn them into an engineering workflow that can outperform repeated Newton-Raphson solves in high-throughput studies. We close with an open roadmap: an industrial‑grade implementation under development at 50Hertz/Elia Group and a clear invitation to collaborate on open interfaces, benchmarks, and integration with LF Energy tooling.

While the world depends on the unimpaired generation and transmission of electrical power, the systems controlling the critical services stay – from a security point of view – often in the shadows. Many assumptions of the past – especially in times of fast redispatch – need to be challenged, and the communication systems have to be monitored more closely. You will learn from real world cases and successful attacks the necessity of looking deeper into the communication of every system to system of systems, from substations up to the control room.

Pre-Packaging CRA and NIS2 Compliance: The SEAPATH Approach - Mathieu Dupré, Savoir-faire Linux

Wednesday September 16, 2026 15:55 - 16:25 CEST

Crossover

The Cyber Resilience Act (CRA) and NIS2 directive impose stringent cybersecurity obligations on industrial deployments, leaving organizations to navigate complex requirements around vulnerability management and supply chain transparency. For LF Energy projects, the challenge is to actively facilitate compliance for downstream users.

Building directly upon the foundations presented at the LF Energy Summit 2025 regarding SBOMs and vulnerabilities in SEAPATH, this session demonstrates how the project proactively addresses European regulations to alleviate the compliance burden on industrial users.

We will detail the implementation of robust security practices: restricted reporting channels, clear security governance guidelines, and automated SBOM generation. Furthermore, we will highlight the integration of VulnScout an open-source vulnerability analysis tool within SEAPATH’s CI pipeline for real-time tracking. Attendees will gain a clear blueprint of how open-source projects can deliver pre-packaged compliance artifacts.

Building the World’s First Open Reference Code Base for SunSpec Modbus and IEEE 2030.5 - Erin Mahan, SunSpec Alliance

Wednesday September 16, 2026 16:30 - 17:00 CEST

Seebühne

This panel will explore the evolution of the world's first open reference code base for SunSpec Modbus and IEEE 2030.5, two communication standards now embedded in grid modernization efforts in several global regions. The discussion will examine how open-source development transformed these protocols from specification documents into deployable, production-grade software infrastructure used throughout the DER ecosystem.
Speakers will discuss historical developments of SunSpec interoperability frameworks and the emergence of open repositories like pysunspec2 and Open SVP, and the recent contribution of a production-hardened IEEE 2030.5 stack developed through commercial deployment experience. The panel will also address technical gaps, cybersecurity considerations, certification challenges, and the importance of collaboration in scaling interoperable energy systems.

DC+: A Fast, Voltage-Aware Alternative To DC Load Flow - Benjamin Petrick, NEZK

Wednesday September 16, 2026 16:30 - 17:00 CEST

Waldbühne

Grid operations are becoming fundamentally more complex. The classical DC load-flow worked well in the past, but its simplifying assumptions are increasingly violated in modern grids with high renewables, reactive power flows, and tighter operational margins.

DC+ is a voltage-sensitive linearization of the AC load flow that retains voltage magnitude, angles, and reactive power while remaining orders of magnitude faster than full AC solvers.
Conceptually, it corresponds to a single Newton step around the AC base case, capturing the direction and severity of violations far more accurately than classical DC, while scaling to millions of N‑1 evaluations per second on GPUs.

DC+ enables a new class of scalable, open optimization workflows:
Potential use cases of DC+ are:
- Fast contingency screening and ranking?
- Topology optimization with voltage awareness?
- Security constrained voltage Optimization?

Decommissioning the Kill Switch:Securing the Energy Grid’s Software Supply Chain With Open Standards - Rossella Sblendido & Andreas Prins Prins, SUSE

Wednesday September 16, 2026 16:30 - 17:00 CEST

Crossover

The European energy grid's modernization embeds physical and digital "kill switches" within smart assets and their software supply chains.
True digital sovereignty cannot be purchased as a proprietary product; it is an ongoing operational discipline. In this session we will dissect how the principles of open source, open standards, and reproducible builds directly mitigate the risk of both physical and logical kill switches. We will move beyond the theoretical to explore the concrete architectural patterns required to build a "Sovereign Stack" for energy systems, providing real examples. Specifically, we will demonstrate how to enforce:
Supply Chain Attestation: Generating and validating cryptographically signed Software Bills of Materials (SBOMs) from source to production edge.
Immutable and Reproducible Edge Environments: Ensuring that operating systems and container platforms deployed on grid edge nodes can be fully audited, rebuilt from source, and run completely air-gapped.
Decoupled Control Planes: Architectural designs that separate software delivery from operational runtime, ensuring that a vendor cannot unilaterally "kill the switch" on a running grid system.
