Optimal location of battery energy storage systems in power distribution network for integrating renewable energy sources

The major challenge in integrating the Battery Energy Storage System (BESS) and renewable energy sources with the existing power system network is to determine the capacity and placement of the BESS in the system. The installation of BESS units at non optimal places can result in an increase in cost, including the system losses and larger battery capacity and therefore, having an effect opposite to the desired. For this reason, the use of a methodology capable of analyzing the influence on some system characteristics of BESS allocation and sizing is very useful for system planning. In this paper, a loss sensitivity based algorithm is proposed for optimal placement and size of the BESS in the distribution system to reduce the distribution power loss. IEEE distribution test data has been used to show the performance of the proposed algorithm.
