Techno-Economic Analysis of Integration of Battery Energy Storage System in Grid-Connected PV System

Abstract

Grid-connected use of photovoltaic (PV) plants with battery energy storage systems is growing as a means of ensuring grid stability and providing sustainable power supply all over the world. An extensive feasibility assessment of an energy-storage grid-connected solar facility in India is provided here as a case study. In order to minimize the amount of grid and fossil fuel-based backup electricity used during power outages and to limit peak load demand, a unique smart net-zero energy management system is designed. An evaluation of the life cycle costs and benefits as well as the levelized cost of energy (LCoE) is provided for optimized solar power plants with and without integration of battery energy storage system (BESS). The HOMER software is used for the optimization and sizing of the equipment for the grid-connected PV system.
