Allocation Method of Pumped Storage Capacity Revenues Based on FAHP-EWM-TOPSIS Method

Under the context of the "dual carbon goals" strategy, the installed capacity and proportion of clean energy in regional power grids have been increasing year by year. Pumped storage, as high-quality and flexible grid regulation resources, have played an increasingly prominent role in improving the optimization of resource allocation, maximizing the consumption of clean energy, and ensuring the safe and stable operation of the power grid on a larger scale. In order to promote the healthy development of pumped storage, it is stipulated that the capacity electricity revenues of pumped storage shall be included in the transmission and distribution price recovery. However, the document does not specify the specific allocation method, and how to improve the allocation method of capacity electricity revenues in multiple provincial power grids based on functions and services of pumped storage. This paper first establishes a comprehensive evaluation index of "safety-environment-economy" for pumped storage based on the functions and services conditions. Secondly, a comprehensive evaluation method for the capacity demand of pumped storage based on fuzzy analytic hierarchy process(abbr. FAHP)-entropy weight method(abbr. EWM)-technique for order preference by similarity to an ideal solution method(abbr. TOPSIS) method is constructed to analyze the capacity demand of pumped storage in various provinces and regions, and sensitivity analysis is performed. Finally, based on actual data from a certain regional power grid, the comprehensive demand for pumped storage capacity in various provinces and regions is determined through case analysis, providing reference for the allocation of capacity of pumped storage.
