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

D-GITT

D-GITT (Detailed Grid Inner Topology Timeseries) is a chapter of OpenSynth (LF Energy) dedicated to power grid descriptive data, including both real and synthetic datasets and the tools to generate them.

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.
