Energy cost analysis by hybrid power generation system

Abstract

The article presents an analysis of unit cost of electricity generation in hybrid power generation system (HPGS). The analyzed hybrid system consists of a wind power, photovoltaic panels and energy storage electrolyzer - fuel cell. There have been shown the balance sheet equations describing the power flow in the analyzed hybrid system. The analysis was carried out for the six variants. Variant I - the source of electricity in the hybrid system is wind, variants II, III, IV, V - electricity is generated by wind turbines and solar panels, variant VI - the source of electricity in the hybrid system is only photovoltaic installation. The unit cost of electricity generation has been designated for: adopted customer profile, the values of intensity of solar radiation and wind speed for the above mentioned variants.
