Study on Energy Storage System Applications, Allocation and Challenges

In recent one decade, application of battery energy storage system (BESS) increased not only for integration of renewable energy sources to grid but also it plays a vital role for energy storage at user end side. Energy storage system application not only limited to renewable energy integration with grid but also its vital application in rural micro-grid & electric mobility. A new era of energy transformation through battery energy storage begins, recently crude oil demand decreased that result results price plummets into negative zone for the first time in history during COVID-19. World's most countries utilize energy storage system to reduce CO
₂
emission and achieve their decarbonization target up to 2030. It is predicted that in near term worlds mobality market and other sector would dependent either BESS or other Energy storage system (ESS) with integration of PV generation as a cost-effective means of reducing pollution and greenhouse effect. The paper presents a comprehensive review of energy storage system techniques, comparison, benefits and brief tabulated summary of research done on ESS allocation in distribution system.
