Study of Low-Voltage Distribution System with Integration of PV-Battery Energy Storage for Urban Area in Developing Country

International audienceThis research work presents a study of Low-Voltage (LV) distribution system integrated with Photovoltaic(PV) and Battery Energy Storage (BES) for an urban area indeveloping country. This work purposes to search an optimaltopology and sizing of PV-BES for supplying the consumers. Amixed integer quadratically constrained programming (MIQCP)is developed at first to find out the optimal topology withminimization of conductor use and phase balancingimprovement. Next, a maximum PV penetration is sized by usingGenetic Algorithm (GA) and Fmincon solver. The sizingstrategies are established to determine a BES capacity accordingto time-varying solar radiation and demand curves. The resultsobtained on an example of LV test system show the validity ofnovel algorithm for optimal topology, PV size and centralizedBES capacity
