摘要：To fully utilize the renewable energy sources and increase the power system reliability with high penetration of renewable energy sources, hybridization with other renewable or nonrenewable sources as well as energy storage systems is highly recommended. This paper studies a hybrid power system consisting of solar panels, a diesel generator, and a pumped water reservoir. In this system, the excess solar energy is used to pump the water into the water storage for later use. When solar energy is not enough to supply the demand, diesel generation and pumped water reservoir help supply the demand. Due to the nonlinear nature of fuel consumption of diesel generator, an optimum amount of power generated by this unit can lead to cost-saving. This leads to an optimization problem, which is solved by an optimization technique proposed in this paper. The optimization used is named manta ray optimization and is based on the improved version of the manta ray foraging technique. The simulation results obtained from the proposed technique, the conventional manta ray foraging technique, and other wellknown techniques are compared to the proposed method to prove better performance and robustness of the proposed method. Three scenarios are analyzed here which are associated with high, normal, and low solar radiation, which are respectively related to maximum, average, and minimum solar irradiance in the studied year. In the case of low solar radiation, optimization is not required as DG is the only auxiliary generation unit. The fuel consumptions using the proposed optimization technique are averagely 6.14% and 5.96% better in scenarios 1 and 2, respectively. Moreover, the robustness achieved by this optimization method is 17.94% and 48.41% higher in scenarios 1 and 2, respectively. (c) 2020 Elsevier Ltd. All rights reserved.
