LF Energy Grid Simulation and Modeling is a special interest group collaborating on open source solutions for power system simulation and modeling

Power grids are becoming increasingly complex to manage as energy resources becoming increasingly distributed and variable. The LF Energy Grid Simulation and Modeling SIG is a collaborative initiative focused on advancing open source tools and methodologies for power system simulation, forecasting, and grid modeling. The group fosters innovation, cross-project collaboration, and alignment with industry standards to enhance grid planning, operation, and resilience in the energy transition. The SIG is designed to support and guide open source projects that enable accurate, scalable, and interoperable grid simulations and modeling.

The projects currently included in this SIG are:

  • Arras: A distributed energy system simulator designed to model and evaluate the impact of high renewable penetration, storage, and flexible demand on grid stability.
  • covXtreme: An open source extreme weather modeling tool that assesses the impact of climate events on grid infrastructure, enabling resilience planning.
  • Dynawo: A high-performance, open source power system simulation engine, supporting dynamic stability analysis for large-scale grids.
  • Grid Capacity Map: A visualization tool that helps stakeholders assess grid hosting capacity, accelerating DER and EV integration.
  • GridFM: An open source framework to enable the emergence of foundation models for power grids.
  • GRIP (Grid Resilience and Intelligence Platform): A modular framework for grid analytics, resilience planning, and decision support, integrating real-time data sources.
  • OpenSTEF (Open Short-Term Energy Forecasting): An open source tool for data-driven energy forecasting, helping DSOs and TSOs predict short-term load and generation trends.
  • Power Grid Model: A Python-based power system analysis tool, providing fast, scalable power flow and contingency analysis capabilities.
  • PowSyBl: An open source library dedicated to electrical grid modeling and simulation.
