Sizing of Energy Storage Systems for Microgrids

Energy storage sizing is an important aspect of the cost effective functioning of microgrids. In this chapter, different energy storage system (ESS) sizing technologies are evaluated. Cost-benefit analysis is a very common method to determine optimal storage sizing. This chapter includes the implementation of an expansion planning problem method for optimal storage sizing. The objective of this method is to minimize the operating cost, maintenance cost and investment cost of the entire microgrid system. In the case study, an optimization problem for determining both the optimal power rating and energy rating of ESS in a microgrid is formulated and solved with mixed integer linear programming ...
