Optimal Placement and Sizing of Various C-Rate Type of BESS for Radial Distribution Network

Peak demand is the most significant factor for the load operating cost determination. Due to heavy burden on national grids at peak hours of day time, the DISCOM utilities get charged heavily according to heavy peak load demand, during peak hours of a day. In this paper optimal BESS placement and sizing is done by Teacher Learner Based Optimization (TLBO), to reduce the hourly peak load variation burden on grid during peak hours. Six different C-Rate types of batteries i.e., 0.5C, 0.08C, 0.25C, 0.33C, 0.167C and 1C have been examined for voltage profile improvement during peak hours without any significant increment in power loss. With the optimal located and sized BESS in distribution side of grid will leads to have a reliable with efficient grid support and reduced power loss help to grid load power demand diversification. In this paper Reliability test system model is used for the reliability analysis per hour for radial IEEE 33 bus distribution networks, and results are verified and simulated in MATLAB 2019b software.
