Optimal Configuration of a Wind/PV/Battery Hybrid Energy System Using HOMER Software

Abstract

A hybrid energy system was put forward according to the renewable resources in a certain area and in order to obtain the optimal configuration of the system, HOMER software was employed to realize the optimization and to implement the economic analysis. The optimal system is consisted of 80 kW PV20 sets of 10 kW wind turbine, 300 kW batteries and 30 kW inventor, and the total investment is $ 709,471, when the capacity shortage is 0 %. The capacity shortage effect was considered and the results showed that the capacity of the battery changed most when the reality of the system declined, in addition the economic performance improved significantly with the Cost Over Electricity (COE) varying from 1.001 $/kWh in 0 % capacity shortage to 0.619 $/kWh in 5 % capacity shortage.
