【摘要】 由于动力电池大量淘汰，为提高退役动力电池的再利用率，增加系统的经济效益与环保性，提出将退役电池作为微电网储能。将风光氢储系统与退役的动力电池结合，考虑退役电池的使用次数和寿命，建立退役动力电池容量配置模型，以最小系统年均总成本为目标函数，负荷缺电率、可再生能源浪费率及过装率为评价指标进行容量优化配置。利用改进的粒子群算法对模型进行优化求解，研究表明，合理退役动力电池容量后，整个系统的年均成本明显下降，系统弃电量也明显降低，系统的经济性、环保性和可靠性得到提高。更多还原

【Abstract】 A large number of power batteries are eliminated, in order to improve the reuse rate of retired batteries, increase the economic benefits and environmental protection of the system, the decommissioned batteries are used as microgrid energy storage. By combining wind, solar, hydrogen storage systems with retired power batteries, taking into account the number of times retired batteries are used and their lifespan, a model for configuring the capacity of retired power batteries is established. The retired power battery capacity is rationally allocated, with the objective of minimizing the annual average total system cost, and evaluation metrics including load shedding rate, renewable energy waste rate, and over-installation rate are used for capacity optimization configuration. An improved particle swarm algorithm is employed to optimize and solve the model. Research shows that with a reasonable capacity of retired power batteries, the annual cost of the entire system significantly decreases, and system wasted energy is also reduced. This approach can enhance the economic, environmental, and reliable aspects of the system.更多还原
