Review on Optimal sizing of Battery energy storage for grid-tied Residential PV system

Abstract

Grid connected PV systems are proving to be worth considering in the adoption of renewable energy technologies. Among other renewable energies, grid connected PV systems continue to attract investors and electricity customers all over the world. Due to interconnection with the utility grid, the system can glean some benefits such as selling PV electricity surplus to the utility grid or purchasing electricity from grid for battery system charging at off peak hours either for self-consumption or selling back to the grid during peak hours. Significant research and development of various optimization methods have been conducted to improve cost, efficiency and system reliability of ES storage to reach a certain maturity in relation to their rise in electric grid. This paper review some of the pertaining works in the area and identifies relevant gaps. Keywords——Battery, electricity surplus, Grid connected PV, Residential, sizing.
