Optimal Placement and Sizing of Various C-Rate Type of BESS for Minimizing the Impact of Intermittent DG Output on Hourly Peak Load Variation in Radial Distribution Network

The motivation of contribution of renewable energy resources for national grid support are increasing by distribution utilities. The intermittent output behavior of these DERs during a day is always been an important concern for power energy engineers which eventually increase the dependency on energy storage units. In this paper optimal BESS placement and sizing is done by Teacher Learner Based Optimization (TLBO), for reduction of intermittent DG output impact on hourly peak load variation. Six different C-Rate types of batteries namely 0.5C, 0.08C, 0.25C, 0.33C, 0.167C and 1C are evaluated for voltage profile improvement with power loss reduction in a day. 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 Modified radial IEEE 33 bus distribution grid network, and results are verified and simulated in MATLAB 2019b software.
