Abstract
Faced with the problem of high wind power curtailment, it is necessary to allocate a certain amount of energy storage power to promote wind power accommodation and stabilize grid operation. A pumped storage power station capacity planning method based on the full life cycle cost is proposed. The method comprehensively considers the life cycle cost of the pumped storage power station, the benefit of additional wind power generation, the coal-saving and etc. Based on the life cycle cost theory, the pumped storage power station capacity planning model aims to maximize the comprehensive benefit of the whole life cycle of pumped storage power station. Using the adaptive hybrid particle swarm optimization algorithm to solve the comprehensive benefit model, the operation strategy and the optimal planning capacity of pumped storage power station in each period are obtained. The influence of the pumped storage power station life cycle costs on comprehensive benefits is analyzed quantitative, and case analysis validates the effectiveness of the proposed method.
