The study of renewable energy generation is particularly important to the building of smart grids. The optimization problem of generation capacity of renewable energy power supply system is studied, which includes wind turbine, photovoltaic power station and small pumped storage plant. Based on analyzing and building the models of renewable distributed generation and energy storage, considering the annual data of load, wind and solar resource, the optimal sizing model based on the minimum annual economic cost is built. The generic algorithm is applied to solve this model. The simulation results show that the configuration program obtained in this method has strong adaptability and can improve the comprehensive utilization of energy and reduce redundant investment.
