Research on Improving Transient Stability of Power System with Distributed BESS and its Coordinated Control Method

The feasibility of battery energy storage system (BESS) in ameliorating power system transient stability has been proved. However, the required BESS capacity is large, which leads to high price. Meanwhile, the improving effect is significantly affected by fault location and BESS location. To address...
