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

COLib-EB
COLib-EB (COLib — Equation-Based) extends CRESYM’s COLib library with a complete equation-based representation layer for all ~400 models defined in IEC 61970-457, making COLib the reference implementation that unites model data, mathematical equations and executable behaviour under one open-source framework.

COLib-SOGL
COLib-SOGL provides TSOs with the technical architecture, processes and simulation methodology needed to comply with their SO GL obligations for dynamic data exchange and stability assessment — covering conventional equipment, HVDC systems, SGUs and FACTS devices.

CSL-TD (ReLife)
CSL-TD (Causal Survival Learning with Time-Dependent covariates) develops a rigorous methodological framework for causal survival analysis applied to industrial assets, enabling operators to quantify the true effect of controllable variables — maintenance strategies, operational decisions — on asset time-to-failure, using observational data alone.
