Techno-Economic Evaluation of On-Grid Battery Energy Storage System at Peshawar using Homer Pro

Abstract

The shortfall of electrical energy has been a major concern of developing countries like Pakistan which has been addressed mostly by means of temporary solutions like rental power plants and independent power producing plants most of which are expensive solutions along with a lot of emission of harmful gasses and pollute the atmosphere. Grid connected renewable energy based power generation near the load centers can resolve the above issues but at the same time these RE based generation plants are considered to be unpredictable as the renewable energy is variable in nature. Therefore, introduction of battery energy storage systems in these RE based systems can be a possible solution to the problem. In this research work a grid connected hybrid RE generation system comprising of wind turbines and PV panels with BESS to generate and store electricity is proposed. The rating of all the components has been optimized using HOMER Pro software to enable optimal renewable penetration in the grid at Levelized Cost of Energy (LCOE). Technical and Economic analysis of system with various battery technologies has been performed and the most feasible solution for the selected site has been proposed.
