Frequency Support by BESS – Review and Analysis
Energy Procedia, 2019 Abstract This work reviews and analyzes the feasibility of frequency support by Battery Energy Storage System (BESS). If power generation and load demand are unbalanced, it would cause serious problems on frequency stability. BESS is an effective method to balance power generation and load demand since it has fast response characteristics.
