Transient voltage stability of offshore wind farms following faults on the collector system

This work focuses on the analysis of the transient voltage stability at the point of interconnection (POI) of offshore wind farms following faults on the collector system. In particular, this study studies offshore wind farms that use an AC export system to transfer generated power onshore and investigates transient voltage stability under the influence of operating reactive power support equipment such as static VAR compensators (SVC) and active power support units such as battery storage or generation units at the POI. Operation of SVC and active power support such are widely believed to improve the stability and dynamic operation of offshore wind farms. This study, using the Great Lakes Offshore Wind Study models, determines the precise conditions under which SVC and active power support can improve the transient stability of the system following faults on the collector system.
