Abstract

The transition toward power systems dominated by renewable energy sources (RES) introduces significant challenges to the provision of black start services. Black start units are essential for restoring power following a system-wide outage; however, the gradual retirement of conventional generation reduces the availability of such resources, potentially compromising grid resilience. Offshore wind farms (OWFs) are increasingly considered as viable alternatives for black start support. Nevertheless, their inherent variability and intermittent power output make it difficult to satisfy technical requirements without external assistance. To address this issue, battery energy storage systems (BESSs) can be integrated with OWFs to enhance their black start capability. This paper proposes a probabilistic approach to determine the optimal BESS power rating required during black start operation. The methodology is based on technical requirements specified by the British Transmission System Operator (TSO). Wind generation is modelled using a Weibull distribution, and a worst-case scenario approach is employed to estimate the required BESS output. The results are validated through load-flow simulations, demonstrating that BESS sizing is primarily influenced by OWF capacity and TSO-defined availability requirements. Additionally, the suggested approach offers useful integration principles, lowers operational uncertainty, increases restoration reliability, and greatly increases overall system resilience during black start.
