Control strategies to damp inter-area oscillations using a battery energy storage system

The paper describes our investigation of several control strategies for use with a battery energy storage system (BESS) to damp inter-area oscillation, such as PI controllers and novel artificial intelligence control techniques utilising a fuzzy logic controller to modulate the active and reactive power output of the BESS. Preliminary studies show that both types of controllers can provide significant damping. Fuzzy logic controllers can provide superior performance in its ability to damp machine oscillation. The use of bus voltage signals to control the reactive power output of the BESS is found to provide very little damping.
