Optimal sizing of Battery Energy Storage System for household microgrid

Abstract

Aiming at the peak shaving and poor power quality issues resulted from the intermittent power sources, battery energy storage system (BESS) is generally a key distributed generation unit in microgrid.Therefore this paper presents a sizing optimization method for battery energy storage system in the typical household microgrid based on solar PV and BESS.The mathematic models and the optimization solution algorithm are proposed respectively as to achieve the optimization goal of maximum economic benefit of BESS.The purpose of the proposed method here is to make full use of BESS to improve the system load peak shaving and power quality, as well as take the maximum advantage of the renewable energy resources available.
