CRESYM is a non-profit association, gathering industrial & research organisations and aiming at solving the coming challenges for the future, fast-evolving European energy system.
We foster collaborative R&D works to deliver opensource energy system simulation tools
We foster efficient collaborations on low-TRL R&D issues of general interest.
We promote, and rely on, opensource principles.
We shall curate and maintain useful technological building blocks available for all researchers & engineers.
We also provide additional services (e.g. training, innovation scouting) to our members and to external clients.
Ongoing projects

AI.grids
AI.grids aims to build the first Pan-European AI foundation model for power grid operations through a collaborative ecosystem of system operators, research organisations, and technology providers. Inspired by advances in large-scale AI models in other domains, the initiative aims to develop a shared model capable of learning from diverse grid datasets and supporting multiple operational applications, ranging from forecasting and congestion management to planning and asset monitoring.

DyPSOS
DyPSOS (Dynamic Power System model Optimisation and Surrogates) develops an open-source automated framework that bridges the gap between generic and black-box models, without requiring access to proprietary model internals.

JoDyMoTePS
JoDyMoTePS (Joint Dynamic Modelling & Testing of Power Systems) is an open-source framework enabling TSOs, DSOs, equipment manufacturers and renewable energy developers to share privacy-preserving models of sub-parts of the European interconnected grid and to perform realistic dynamic co-simulations — without any party exposing sensitive data.
