A Comparative Analysis of Demand Response on Different Operational Strategies of Battery Energy Storage System for Distribution System

This paper investigated the impact of different battery energy storage (BESS) operational strategies with demand response (DR) and wind-based renewable generation to enhance the performance of the distribution network. The optimal coordination of multiple BESSs, DR, and wind generation is used to minimize network energy loss. This coordinated operational problem is subjected to the distribution system constraints such as feeder current limit, voltage range, and power balance. The suggested methodology is tested on the IEEE 33-bus radial distribution network. A genetic algorithm (GA) is used to investigate the different operational strategies. The results show that the optimal coordination problem can reduce the system losses and also maintain the voltage within the specified limits. The implementation of BESS with DR and wind reduces 62.42% of network losses and it helps the distribution system operator for the selection of BESS operation strategy when the demand of the consumers is controllable.
