In September 2021, the Carbon Trust commissioned the HVDC-connected OWFs: controller interaction and grid stability (HVDC-CI) study as part of Stage IV of the Offshore Wind Accelerator programme. The Centre formed a collaboration with the French TSO, RTE International (RTEi), to deliver the project.
The HVDC-CI project investigates the risks associated with the integration of, and interaction of HVDC connected Offshore Wind Farms (OWFs). The project aims to identify the key contributing factors of controller interactions and their associated risks with focus on HVDC connected OWFs power system infrastructures, also considering nearby generators and potential sub synchronous torsional interaction (SSTI) phenomena. It then builds on these findings to develop a scope of study to efficiently assess these risks across project design stages as well as investigate mitigation actions.
The HVDC Centre is leading work packages 1 & 4 and providing support to the other work packages led by RTEi.
