Sharing Model of Electrochemical Energy Storage Based on Cooperative Alliance
With the confirmation of the strategic goal of"reaching the peak of carbon emissions by 2030,and achieving carbon neutrality by 2060",the construction of novel power systems has become a key sector in the country's major strategic layout during the"Fourteenth Five Year Plan"period.Therefore,the construction of energy storage facilities as a flexible resource regulation will constitute an important guarantee for the safe and stable operation of the power systems.This article proposes a"cooperative alliance"shared energy storage solution consisting of new energy stations and energy storage operators to address the difficulties in reducing the cost of energy storage on the power supply side at present.Energy storage utilizes its surplus capacity to participate in the grid auxiliary services while meeting the regulatory needs of new energy stations within the cooperative alliance,solving the basic problem of low energy storage willingness in the construction of new energy stations.At the same time,in the scenario of tracking the planned output and secondary frequency regulation of the power grid,simulation and quantitative analysis are conducted to compare the differences in investment efficiency and resource utilization efficiency between the"cooperative alliance"shared energy storage and the self-built energy storage of new energy.Based on the proposed Shapley value based energy storage capacity pricing method,the commercial feasibility of the"cooperative alliance"shared energy storage model is analyzed.The results indicate that the"collaborative alliance"shared energy storage model enhances the resource utilization efficiency of energy storage and exhibits a higher degree of fairness in profit distribution.
