Redispatch Without Black Boxes: Load Forecasting With OpenSTEF at E.ON - Alexander Geiseler, E.ON Digital Technology

Tuesday September 15, 2026 11:05 - 11:35 CEST

Seebühne

For reliable and cost-efficient distribution grid operation and redispatch management, accurate short-term forecasting is a core prerequisite. At E.ON, we originally relied on vendor-built “black box” forecasting solutions and experienced the familiar trade-offs: slow iteration cycles, limited transparency, and dependence on external roadmaps. In this talk, I’ll share our journey to an open-source target picture for transformer load forecasting in a redispatch context. After a quick intro to the redispatch problem and our system setup, I’ll walk through our OpenSTEF-based approach. I’ll then present results from a real benchmark against an external model and the practical lessons learned; what mattered, what didn’t, and where open source helped us move faster. Finally, I’ll cover the organizational path: how we navigated compliance and governance with our Open Source Office to turn from user into contributor.

Closing Gaps From Commercial Tools in German Redispatch 2.0 With Open Source Tools - Jordanno Paiva, Accenture

Tuesday September 15, 2026 11:40 - 12:10 CEST

Seebühne

Redispatch volumes have increased enormously over the past year, creating new challenges for existing technologies, tools, and processes. These challenges become particularly visible in settlement and billing, which sit at the end of a long chain of operational and data-processing steps.

The use of multiple commercial tools from different vendors can make data access, process transparency, and adaptation to changing requirements difficult. To address this, Bayernwerk has started using open-source tools to improve data transparency and support error detection, correction, and analysis in the Redispatch 2.0 process.

The initial experiment was successful and, beyond the original use case, has attracted new users across the organization. Making data more openly available internally has enabled new applications across departments and contributed to a broader shift in how data is used.

The next challenge is to scale and industrialize these tools to meet growing internal demand, while integrating more advanced features where LF Energy and other open source tools can play an increasingly relevant role.

Connecting LF Energy’s Projects: A Mini-City Prototype for the Digital Grid Ecosystem - Darshan Chawda & Nao Nishijima, Hitachi, Ltd.

Tuesday September 15, 2026 13:10 - 13:40 CEST

Seebühne

LF Energy has a growing ecosystem of open-source projects for forecasting, digital substations, data-driven operation, and more. However, for many users, one question remains difficult: how do these projects fit together in a realistic digital grid workflow?
Over the past year, we explored many LF Energy projects and analyzed how they can work as parts of a larger grid ecosystem. Based on this, we're building a miniature city-grid prototype in our research lab that connects different projects across a shared operational chain. For example, one workflow starts with load and renewable forecasting, uses grid-model calculations to assess network impact, and surfaces the resulting event to an operator workflow.
The session will include a demo walkthrough using recorded lab segments, architecture diagrams, and data-flow examples. It will show how projects such as OpenSTEF, SEAPATH, PowSyBl, OpenGridFM, and OperatorFabric can fit within the same architecture. Attendees understand where to start, what role each project can play individually, and how they can be connected to solve practical digital grid problems. The session will also highlight integration gaps for community discussion.

Selectivity as Code: Closing the Loop Between PowSyBl and SEAPATH - Aurélien Wataré, RTE INTERNATIONAL & Nevena Popović, RTE international South-East Europe

Tuesday September 15, 2026 13:45 - 14:15 CEST

Seebühne

PowSyBl runs load flow in production at TSOs; its short-circuit side is younger. We do not need a perfect fault engine to make the next leap. Treat PowSyBl as a *grid engine* — it gives the short-circuit power Scc, the fault current Icc, line parameters and source strength, the boundary conditions a protection study needs since relays are set on Icc min and max. Feed those into the *real* protection, virtualized on a SEAPATH base, close it into a software loop over one zone, and you test selectivity the way software teams test code: deterministically, repeatably, in the open.

Grid Enhancement Platform: Operationalizing Open Source for Real-Time, Risk-Aware Grid Management - Ankur Arohi, emsys grid services GmbH

Tuesday September 15, 2026 14:20 - 14:50 CEST

Seebühne

Modern power systems are undergoing a structural transformation that planning tools were never designed to handle. System operators today manage this complexity with tools built for a different era, decisions made on intuition shaped by experience rather than probabilistic foresight.
The Grid Enhancement Platform (GEP) solves this software architecture challenge as an open-source reference architecture. Built on a modular, loosely coupled stack of four mature projects LF Energy’s PowSyBl, Power Grid Model, OpenSTEF and Pandapower. At day-ahead clearing, GEP ingests the cleared positions and runs a forward-looking network state simulation. Using the probabilistic outputs at the asset level, propagated upward through aggregation engine and evaluated against the network model in Power Grid Model and PowSyBl, the platform generates a time-series of nodal state distributions. At the aggregation level, flexibility assets-batteries, demand response contracts are modelled as degrees of freedom that can be co-optimised against both the energy market objective and the network constraint objective simultaneously. The result is a genuinely localised, network-aware dispatch signal .

Asset Thermal Models: Expanding the Family of Thermal Models To Cables and Switchgear - Anna Van Velsen & Jesse Tjebbes, Alliander

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

Seebühne

We need the capability to thermally model all components in the chain of assets. The global energy transition is rapidly reshaping electricity systems, driven by decarbonization, electrification, and the integration of renewables. These developments introduce new operational challenges for grid operators, including increased congestion and the need to maximize existing grid capacity while ensuring reliability.

Building on our Transformer Thermal Model, we add two new members to the family of thermal models: Cable Thermal Model (CTM) and Switchgear Thermal Model (SGTM). These models estimate asset temperatures based on load, ambient conditions, and technical specifications. Together, they allow operators to identify bottlenecks, assess hidden capacity, and mitigate congestion risks. As this now enables operators to model most primary components in the grid, the applicability and value increase exponentially!

In this talk, we demonstrate how we apply these models in practice across multiple asset types, enabling higher asset utilization, optimal grid planning, improved monitoring, and more efficient system operation.

Phlowers: An Ecosystem for Physical Simulations of Overhead Lines - Jérémy Wang & Adrien Goeller, RTE

Tuesday September 15, 2026 16:30 - 17:00 CEST

Seebühne

Understanding, simulating and predicting the behavior of overhead lines and their supporting structures (including electrical towers) is essential for securing grid maintenance and extending asset life. Phlowers provides tools to achieve this in a simple way, despite the complexity of the underlying algorithms.

Phlowers is an Open Source ecosystem that brings mechanical and thermal modeling of overhead lines to engineers, researchers and operators, including those working offline. In the future, it will integrate the modeling of supporting structures (pylons/towers) to simulate mechanical constraints and interactions within the grid.

The ecosystem currently includes Python libraries for simulations and an offline web application called Stellar. It enables users to customize models, integrate their own data and adapt tools to operational needs. It will also support large-scale batch computations to assess maintenance policies, simulate multiple scenarios and optimize long-term asset management strategies.

In this session, we will explore its architecture, use cases and contribution to innovation in grid asset management.

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.

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.

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.

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.

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.

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.

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.
