A Review on Energy Storage Systems Planning in Active Distribution Networks and its Applications

With the restructuring of power systems, increase of renewable energy sources, and as networks become smarter, power systems are facing new challenges such as uncertainty in available energy resources. An appropriate solution to address these challenges are to use energy storage systems. Therefore, sizing, location, and selection of energy storage systems are important to maximize their benefits. This paper is a review of research studies, examines the types of energy storage systems, their applications, methods of formulating objective functions and methods of solution. Another purpose of this paper is to investigate the issue of optimal Energy Storage System (ESS) planning in active distribution networks. It also provides a broad classification of the Storage Expansion Planning (SEP); and by reviewing several papers, it identifies trends and challenges, and suggestions for future work in this area.
