This paper investigates an off grid photovoltaic / wind turbine / diesel generator hybrid system. The hybrid system is equipped with a flywheel storage for power quality and reliability. Homer software is used to analyze the proposed system. The analysis is performed in terms of net present cost, annual cost, uniform cost of energy, fuel consumption and the share of the hybrid system elements in energy production. Also, the system is compared to the hybrid system without flywheel storage economically and environmentally.
