Allocation of Battery Energy Storage Systems (BESS) to Mitigate FIDVR in the Con Edison Transmission Systems

Fault-Induced Delayed Voltage Recovery (FIDVR) is an unexpected time delay in the recovery of voltage to its nominal value following the normal clearing of a fault. Typically, the delay can last seconds to tens of seconds, which has attracted attention as a significant issue in power systems. Inverter-based renewables such as battery energy storage systems (BESS) show the potential to provide voltage support during FIDVR events. This paper studies the optimal allocation of BESS to mitigate FIDVR in Con Edison of New York, including the BESS control strategy, BESS size, and BESS locations. The study is carried on by means of computer simulations in Siemens PTI software PSS/e.
