LF Energy Summit Europe 2026

Building on the successful deployment of R#SPACE, which virtualizes substation automation functions, RTE launched the VIP’R R&D project to address a key question :
Can a 63 kV substation be reliably protected using virtual distance protection functions from different vendors (ABB and Schneider Electric) running on the open-source SEAPATH platform?

This demo will showcase IT and OT tests performed in RTE’s lab to demonstrate the real-time performance and deterministic behavior of the distance protection function within a SEAPATH cluster.
The session will include an open discussion with the audience on the test setup, results, methodology, and tools use with the participation of Schneider Electric.

As LF Energy SEAPATH adoption continues to grow across the energy ecosystem, making onboarding and first-time evaluation a key topic for new users and contributors.

This session will demonstrate how the SEAPATH community has streamlined the first-user experience to help newcomers get a functional SEAPATH instance running in their lab as quickly and smoothly as possible. Attendees will discover the latest onboarding improvements, including the refactored documentation, the new “Getting Started” experience, the SEAPATH Installer, and the different community resources available through the SEAPATH GitHub ecosystem.

Through a live demonstration, the session will guide users step by step from initial setup to a ready-to-use SEAPATH environment, while highlighting the tools and workflows that simplify experimentation, evaluation, and contribution. The presentation will also share lessons learned from community feedback and explain how these improvements are helping reduce the barrier to entry for industrial-grade virtualization in digital substations.

As the energy sector accelerates its transition toward decentralized power, the need for robust, open-source grid automation has never been greater. LF Energy’s SEAPATH project provides this critical framework, but a resilient platform requires an equally resilient foundation.

In this session, we are thrilled to announce a major milestone: the enablement of SUSE software for the SEAPATH project is officially complete. We will walk through the journey of bringing SEAPATH to the SUSE ecosystem, discussing the technical integration and how leveraging SUSE's enterprise-grade stack provides the security, stability, and lifecycle management that critical energy infrastructure demands.

Key Takeaways:

The Milestone: What the completed SUSE enablement means for the SEAPATH ecosystem and open-source energy innovation.

Under the Hood: How SEAPATH leverages SUSE technologies for optimal performance at the edge.

Real-World Impact: How operators can now confidently deploy mission-critical solutions on this stack.

Join us to see how SEAPATH and SUSE are ready to power the substations of tomorrow!

Join this demo session to explore Dynaωo, an open-source suite of time domain simulation tools for power systems. Through real-world use cases at full grid scale, we will showcase the tool’s current capabilities, including its ability to model complex grid behaviors, simulate disturbances, and analyze system stability. We will demonstrate how both academic and industrial users can quickly get started with Dynaωo, enabling them to leverage its powerful time domain simulation capabilities for their specific needs.
This session will highlight Dynaωo’s integration with PowSybl, another open-source tool under the Linux Foundation Energy umbrella, to demonstrate how seamless interface enhances workflows for researchers and industry professionals. Attendees will gain hands-on insights into Dynawo’s modular architecture, its flexibility for customization, and its potential for industrial applications.
Whether you are a developer, researcher, or grid operator, this demo will illustrate how Dynaωo can support your dynamic simulation needs while fostering collaboration within the open-source energy community.

PowSyBl is becoming more and more widely used by the power grid community. PyPowSyBl is the entry point to this ecosystem for a lot of users, bringing most of the functionalities of PowSyBl to Python development.

We propose to demonstrate both the core features of the package (network manipulation, loadflow computation, security or sensitivity analysis, visualization...) and give a glimpse into the more recently added features.

It will allow both new members of the community to discover how PyPowSyBl works and members already using it to know more about features they might not use and new ones.

As power grids transition to highly integrated cyber-physical systems, the complexity of control architectures poses a major challenge for resilience and scalability. This session introduces CyberGridML, a modeling language based on MBSE (Model-Based System Engineering) and the OMG SysML v2 standard, designed to evaluate the impact of digital architecture on operational performance.
We will demonstrate how to model a modular SCADA system across three architectural layers: functional control, digital resources and hazard modeling (computing failures, network failures, network latency, etc.). Through a concrete case study, we show how the CyberGridML methodology enables a rigorous assessment of trade-offs between resilience, operational efficiency and cost, and how these models can be leveraged within digital twin environments such as TwinEU control-room twin to support realistic experimentation and training.

In this demo, Daniel Roesler, founder of DRX Gateway, will show a demonstration of the first implementation of LF Energy's CDS protocols on the DRX Gateway platform. The demo will include three parts: (1) how a utility can launch and configure a server that complies with CDS specifications, (2) how external companies can automate connecting to that server using CDS standardized protocols, and (3) how secure data exchange and communication can take place using CDS specified APIs. The goal of this demonstration is to show how important the CDS project is to unlocking scalable connectivity in the energy industry.

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.

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.

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.
