Sizing and Allocation for Solar Energy Storage System Considering the Cost Optimization

The use of renewable energy sources (RES) for energy has increased rapidly in the last few years. This encourages the use of technologies to be integrated with RES to help in enhancing the power system reliability and reducing the total operation cost. The energy storage system (ESS) is one of these technologies. This paper represents firstly an optimization technique for an ESS power sizing in a power system that integrated with PV cells. Secondly, optimally allocate and distribute the sized ESS. The optimization technique used in this paper is the mixed-integer linear programming (MILP) method. Moreover, this paper discusses also the effects of integrating a storage system on the distributed generators unit commitment and economic dispatch in the power system.
