Feasibility Study of Small Scale Battery Storage Systems Integrated with Renewable Generation Technologies for Sri Lankan Domestic Applications

Abstract

The purpose of energy storage technologies is to ultimately increase the efficiency of renewable energy generation methods and systems and decrease the global CO₂ emissions to tackle the Sri Lanka government’s sustainability targets. This research aims to provide a summary of energy storage and to determine the feasibility and optimal battery storage technology for a 3-bedroom house when integrated with renewable generation source such as solar PV. This research was carried out by using a renewable energy system analysis tool called HOMER pro, solar PV were modelled and simulated with each type of battery, lithium ion and lead-acid batteries, in grid-connected mode. To get a better understanding of how battery storage could be utilized, system was simulated in Matara, located at the south coast of Sri Lanka.
