Technical and economical design of solar-wind distributed generation power plant with battery storage for a zone far from the national electricity grid in Ahvaz

In this paper, a designate of a small scale solar-wind power plant, integrated with battery storage was performed in order to supply the energy demand of a suburb region of Ahvaz, Iran. The aim of this work was to minimize the expenses by help of Homer software with consideration of the amount of the consumed electricity, solar irradiation and wind velocity for the considered region. To optimize the system, Particle Swarm Optimization (PSO) method was used. The simulation results indicates that in the proposed plan, almost 45% of the costs are spent for purchasing, maintaining and replacing the batteries, while, the portion of solar and wind equipment are 15% and 20%, respectively.
