Shared Energy Storage Trading Mode of New Energy Station Group Considering Energy Storage Performance Difference

Abstract

To clarify the complex coupling relationship between the technical and economic characteristics of energy storage batteries participating in sharing and the price mechanism and income distribution of shared energy storage, a shared energy storage trading mode of the new energy field and station group considering the difference of energy storage performance was proposed. Firstly, the operation mode of the new energy field group shared energy storage based on self-assigned energy storage was proposed to break the constraints of new energy field stations participating in energy storage resource shared interaction. Secondly, considering the health status of batteries in different energy storage resources and the interests of multi-participants in shared energy storage, the price mechanism and income distribution method of shared energy storage on the power generation side considering the different technical and economic characteristics of energy storage units were constructed. Finally, a numerical example was used to verify the feasibility of the proposed generation side shared energy storage trading mode considering the health status of energy storage batteries. The research results provide theoretical and decision support for the economic sustainable development of shared energy storage on the power generation side.
