摘要: 为最大化利用退役动力电池的全生命周期价值、解决共享储能在电力系统扩展规划方面需兼顾多方利益的经济性难题,计及逐渐增加的新能源装机容量与负荷需求,提出考虑退役动力电池衰减特性的发电侧共享储能长期规划模型。首先,设计基于退役动力电池的发电侧共享储能运营模式以打破能量共享壁垒,使其既能服务于自身新能源场站又可实现多个新能源场站间的能量互济、必要时还能参与电网的动态调频。其次,考虑退役动力电池衰减特性构建多个新能源场站自配并共享储能的长期规划模型,模型基于合作博弈以应对多方利益诉求冲突给资源优化配置带来的经济性挑战。最后以算例仿真验证所提发电侧共享储能运营模式及长期规划模型的可行性。

Abstract: To maximize the life cycle value of retired batteries and solve the economic problem of taking into account the interests of multiple parties in the allocation of shared energy storage. Considering the impact of the gradually increasing installed capacity of new energy on the expansion planning of power systems, a long-term planning model of shared energy storage on the generation side considering the attenuation characteristics of retired batteries is proposed. Firstly, the operation mode of shared energy storage the generation is designed to break the energy sharing barrier so that it can not only serve its new energy stations but also serve others, and participate in the dynamic frequency modulation of the power grid. Secondly, considering the attenuation characteristics of decommissioned batteries, a long-term planning model of self-distribution and shared energy storage is constructed. The model is based on a cooperative game to deal with the economic challenges brought by the conflict of multi-interest demands to the optimal allocation of resources. Finally, the case studies are given to verify the feasibility of the proposed generation side shared energy storage operation mode and long-term planning model.
