PowSyBl: TSO Cooperation Through Building Blocks - Nicolas Omont, Artelys & Alice Caron, RTE

Tuesday September 15, 2026 10:30 - 11:00 CEST

Waldbühne

During the last years, the PowSyBl ecosystem has expanded in many directions around the core module dedicated to grid data management, allowing the collaboration of an increasing number of organisations. As the workhorse of power systems, Open Load Flow is leading the adoption cycle with live projects for load flow, security analysis or sensitivity analysis at many TSOs and Coordination Centers. The advanced optimization tool OpenRAO is also a leading operational remedial action optimizer in Europe. Beyond computation modules, many users also adopted PowSyBl thanks to its easiness of use in day-to-day scripting through the python interface, and to grid and substation visualization features. The technical ecosystem is also widening with projects like the dynamic simulation module Dynawo and the grid study platform GridSuite. These last projects are open-source and are an open invitation to start cooperation. The session will provide an overview of the ecosystem, providing, for each module, the main features and use cases, the maturity status, and the roadmap. Eventually, through some examples, the way PowSyBl governance allows to start new cooperations will be presented.

PowSyBl: A Service Provider Business Model - Nicolas Omont, Artelys

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

Waldbühne

This session presents Artelys' vision of a sustainable business model around the PowSyBl open-source framework for power system modelling.

The approach relies on a clear separation between strategic governance, technical steering and community contributions, enabling transparency and alignment across stakeholders (TSOs, RCCs, utilities, vendors). The roadmap is not imposed by a vendor but co-defined by contributors and users, who can influence priorities through governance bodies and structured collaboration.

From a business perspective, value is created through services: integration, custom developments, and especially long-term support & maintenance of shared modules. This model leverages mutualization: several users co-finance core components, ensuring sustainability of complex software while avoiding vendor lock-in.

The session will illustrate how open-source approach enables both flexibility for individual projects and efficiency at ecosystem scale.

Generation and Load Interconnection Studies in the US Using PowSyBl - Dio Stamatiadis, Piq Energy

Tuesday September 15, 2026 11:15 - 11:25 CEST

Waldbühne

Capacity screening studies help US generation and large-load developers evaluate project size against available network capacity. Once a project size is selected, system impact studies determine project-specific impacts and upgrade costs. Developers often need to run tens or hundreds of sensitivities to understand risk, compare sites, and navigate the interconnection process, making scale, speed, and accuracy critical. In the US, these studies are most commonly performed with commercial planning software. While open-source alternatives exist, they are still rarely used in industry-grade workflows.

We will show how we are incorporating PowSyBl into our power system analysis platform as an alternative engine for US studies. We will cover why we selected PowSyBl after evaluating other open-source options, what it took to adapt it to US planning conventions, how its results compare with commercial tools, and lessons learned bringing open-source power-system analysis into production workflows. We will also discuss where we plan to extend its use next, including broader study coverage, deeper workflow integration, and contributions back to the ecosystem.

How To Industrialize an Open Source Approach Around PowSyBl - Régis Le Drézen, Agnès Triponel & Sébastien Dinot, Sopra Steria

Tuesday September 15, 2026 11:25 - 11:35 CEST

Waldbühne

Transmission system operators face structural challenges: sovereignty, security, safety, efficiency, digitalization …
In this session, Sopra Steria shares a practitioner’s journey of embedding LF Energy’s PowSyBl into a real TSO production program for RTE. We cover two concrete contributions shipped to the open source community: decoupling the network-viewer component from any frontend framework (React/Angular agnostic), enabling simultaneous dual-value display (P active and Q reactive) on grid lines. Beyond the code, we discuss how an IT company structures its OSPO, open source governance (Licence Rules Book), and the cultural shift required to move from “consumer” to “contributor” in a critical infrastructure context.

Scaling Grid Security With Open Source - Hugo Pfister & Jorn van der Landen, TenneT Netherlands

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

Waldbühne

The power grid is changing fast, and the systems behind it are under pressure. More data, tighter timeframes, increasing congestion, and regulatory requirements are pushing traditional grid security tools beyond their limits. At TenneT Netherlands, legacy tooling was simply no longer fast and adaptable enough to keep up with this new reality.

By combining the open source PowSyBl framework with a cloud-native orchestration platform (ReFlow), TenneT rebuilt its grid security analysis from the ground up. The result is a step change in performance and capability: reducing calculation runtimes from minutes to seconds and enabling a fundamentally different way of working.

This session will show how we:

- Moved from monolithic legacy tooling to a modular, scalable architecture
- Used open source to accelerate delivery and avoid vendor lock-in
- Established what it takes to run open source in a mission-critical environment
- Strengthened operator support by providing an integrated view across analyses through modular design

How To Orchestrate RL Agents for Topological Remedial Actions Using PowSyBl’s Operator Strategy - Harald Jendrian, TUM School of Engineering and Design

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

Waldbühne

We bring LF Energy's PowSyBl into the control room as a decision support tool, combining grid analysis with Reinforcement Learning to solve post-contingency problems immediately. Increasing complexity amplifies overloads, demanding corrective actions beyond what manual operator heuristics and existing tools can deliver in time. Open-source RL agents backed by PowSyBl learn curative topology reconfigurations for the Simbench EHV network in Node-Breaker representation. Agents observe bus voltages, line loadings, injection profiles, and switching states. The action space controls breakers and disconnectors via valid action masks for node splitting, busbar re-assignment, and line (dis)connection. Remedial actions are injected as Operator Strategy actions inside PowSyBl's Security Analysis, faithfully reproducing N-1 assessment in training. We discuss reward design, bonuses, penalties, and action-masking. The talk ends with a live demo: a Leaflet map with colour-coded loadings, interactive single-line diagrams, forecast plots, and a control panel triggering Security Analysis and visualising corrective actions via PowSyBl's Operator Strategy in real time.

AINETUS - AI for Safety-Critical Network Infrastructures - Gil Sampaio, INESC TEC

Tuesday September 15, 2026 14:20 - 14:30 CEST

Waldbühne

This talk will present the LF Energy project AINETUS, which implements AI-based decision-support (AI assistant) capabilities for power system operations, addressing the increasing complexity of modern grids driven by high levels of renewable energy integration. Traditional tools are often limited in their ability to anticipate system dynamics and support operators under rapidly changing conditions. AINETUS tackles this gap by combining data-driven techniques with domain knowledge to provide proactive, explainable, and operator-centric support.
It will show a set of components designed to work together or independently within existing operational environments, in particular: (1) Human-AI interaction tools that enhance situational awareness. (2) Reinforcement learning agents that identify optimal operational strategies, capable of adapting to evolving grid conditions while respecting physical constraints.
(3) Explainability tools and uncertainty estimation that help to provide transparent recommendations to support informed decision-making.
AINETUS is designed to integrate with existing platforms and workflows, leveraging environments such as Grid2Op for training and validation.

Towards Industrial Grid Foundation Models With PowSyBl and GridFM - Nicolas Lair, Artelys

Tuesday September 15, 2026 14:30 - 14:40 CEST

Waldbühne

This lightning talk presents the integration of the PowSyBl framework into the datakit of GridFM, two flagship LF Energy projects, to bridge foundation models and industrial-grade power system simulation. GridFM relies on large-scale synthetic data generation, such as load flows, to train a foundation model, where training data quality directly impacts model performance during inference.
The integration of PowSyBl brings several key benefits. It extends GridFM to realistic and industrial-grade network models by supporting multiple formats (CIM, CGMES, PSS/E), enabling the use of richer and more representative datasets. It provides access to an industrial-grade load flow solver through Open Load Flow, improving the physical consistency and accuracy of generated data. Finally, it enables the generation of dynamic simulation data through Dynawo, opening the way to foundation models trained on both static and dynamic grid behaviours.
Overall, this integration is a key step toward the industrialization of grid foundation models, enabling their application to real-world power system studies.

OpenSynth Dataset Extension - RTE7K Challenge - Pierre Olivier Cayetanot, CRESYM & Josh Cooney Mercadal, eRoots Analytics

Tuesday September 15, 2026 14:40 - 14:50 CEST

Waldbühne

Last year, the LF Energy project OpenSynth expanded with the launch of D-GITT, an open data hub featuring RTE7K: a dataset of the whole French transmission grid, including topological changes over three years. Striking the interest of other actors in opening their own dataset, RTE7K demonstrated its values as a realistic, open benchmark for grid analysis.

Now, RTE, CRESYM, eRoots and IRT SystemX joined forces to launch the RTE7K Challenges, a series of challenges centered around the dataset. The first one, kicking off at this summit, focuses on tackling the "missing piece" for running powerflows on the RTE7K dataset: power injection data. Participants are tasked with producing realistic, synthetic injections using whatever public data and methodology they can come up with. As well as being an enticing challenge for participants, the outcome will be a critical extension to RTE7K that will enable further users to test and validate tools using data comparable to what was previously exclusive to TSOs.

Future challenges will explore topics like AI-driven grid topology management, power flow analysis and more, pushing the boundaries of what’s possible with open grid data.

Speakers

Waldbühne

We ran a comparative AI audit of the microgrid standards corpus — IEEE 2030.5, IEC 61850, CIM, OpenADR 3, ISO 15118, IEEE 1547, SunSpec — using Claude, Mistral, and a locally hosted model with identical prompts and metrics. This lightning talk shows the convergent findings: which clauses already cover AI-agent operation on DER, where the gaps are, and the v0 interface contract (GAIFARE) we drafted in the ORES repo to fill them — capability declaration, bounded authority, decision auditability, data governance. Prompts, metrics, and gap map are public.

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.

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.

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.

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?
