Influence of battery energy storage system on steady state stability of power system

The battery energy storage system is utilized for shifting system loads from daily peaks to daily lows. More interests has been renewed to furthering the function of the BESS as a tool to enhance power system stability, aid power transfer, improve reliability and power quality. This paper investigates the influence on transfer capability, small signal stability and steady state stability boundary of the power system with BESS. Results from analytical and simulation studies reveal the technical feasibility of using BESS for improving steady state stability of power system.
