【Abstract】 Traditionally, the design of energy storage capacity configuration in power system is not reasonable, resulting in unsatisfactory effect. Therefore, an optimal configuration method of energy storage capacity in AC-DC hybrid power system based on variable life model was proposed. Firstly, AC-DC hybrid power system model was built. Secondly, the power capacity and energy storage capacity of energy storage capacity of AC/DC hybrid power system were analyzed. And then, the optimization configuration method of energy storage capacity based on variable life model was adopted to set the highest net profit as the optimization goal. Energy saving profit, environmental protection profit and capacity profit were optimized under the constraints of operation of system and power plant, system reserve capacity and battery energy storage. Finally, the optimal configuration of energy storage capacity in AC-DC hybrid power system was achieved. Simulation results show that the proposed method needs short configuration time and high efficiency. The user satisfaction is up to 99%. This method can provide an important reference for the optimal allocation of energy storage capacity of AC-DC hybrid power system.更多还原
