Optimal Energy Storage Placement and Sizing in Distribution System

Abstract

A method to obtain the optimal placement and sizing of battery energy storage system (BESS) to reduce the voltage fluctuation and total active power losses in the distribution system was suggested in this paper. Harris' Hawks Optimization (HHO) algorithm was used to perform the optimization process. Three different cases with different objective functions were involved in determining BESS optimal placement and sizing. The effects of installing different number of BESS in the distribution system for the purposes of voltage regulation and power losses reduction were investigated in this work. The efficiency of the HHO has been verified by comparing it with the Whale Optimization Algorithm (WOA). The results showed that HHO has excellent results in terms of achieving BESS’ optimal placement and size for all cases. When BESS are placed at multiple buses, preferable results can be obtained.
