Sizing of Battery Energy Storage System for Peak Reduction of Commercial Users using Historical Data

Abstract-Solar plus methods for commercial and industrial customers are needed to reduce carbon emissions and meet the nation’s energy needs. Solar-plus refers to combining a solar PV system with energy storage, wind energy, or load control. Solar plus approaches such as Photovoltaic with battery energy storage seem promising solutions. However, it is vital to examine the economics for major utility customers like commercial and industrial users before introducing solar plus for end consumers because end users’ economics are also highly crucial for adoption. This paper presents a case study of a present academic institution with a connected load of 3 MW and a PV system with 440 kW of power. Using historical smart meter data of one-year duration, this paper investigates the optimal sizing of battery storage systems for peak reduction and minimization of electricity bills.
