Optimal Sizing of BESS for Attaining Frequency Stability Under High PV Penetration

Frequency stability has become a major concern for grid operators as photovoltaic (PV) penetration increases in existing grids. Battery energy storage system (BESS) is an intriguing supporting mechanism that assists in enhancing the frequency response of such grids. However, excess BESS installation can impose substantial financial issues, whereas inadequate installation may fail to support the gr...
