Integration of Pump-Storage Batteries in Offshore Wind Farms: Evaluation of Effects on Power Exchange

While having a significant contribution to the total installed capacity, rapid development of offshore wind farms (OWFs) pose technical challenges for supply-demand balancing and onshore grid capacity. Various storage technologies are being considered to integrate in OWFs to combat these issues in the local offshore grid. This paper introduces a unique concept of pump-storage batteries which can enhance demand and supply management of the OWF and improve grid utilization. This paper will present specifications of this proposed battery model, technology used for control of pump-turbine applications, and presents the simulation set-ups and results for week-long operation of the battery.
