Research on Cost Allocation of Ramp Services Using Independent Energy Storage Dynamic Shapley Value

Since the “double carbon target” was proposed, independent energy storage, as the backbone of the future provision of ancillary services, and the price theory and mechanism that corresponds to it also need to break through. In order to stimulate the enthusiasm of energy storage to provide auxiliary services, we need a reasonable cost-sharing mechanism for auxiliary services. In this paper, after obtaining the auxiliary service cost calculation of independent energy storage based on the life cycle theory, we constructed a two-stage dynamic Shapley value cost sharing method, and calculated the dynamic Shapley value and the dynamic sharing consistency test. In this paper, by taking the data of a province in Northwest China as an example, the dynamic Shapley value method of climbing auxiliary service cost apportionment and apportionment ratio of wind power, photovoltaic and users are obtained, and the results show that: the apportionment amount of the cost of climbing auxiliary service that the users need to bear and the apportionment ratio are much larger than that of wind power and photovoltaic, and the apportionment ratio of wind power and photovoltaic is related to the volatility of its power output. It provides a reference for the construction of the cost-sharing mechanism of climbing auxiliary service for energy storage in China.
