Abstract: The constraints on natural resources of small and medium-sized hydropower stations in Hunan Province are characterized by their widespread distribution and inefficient management. To strengthen the unified supervision and enhance regulatory capabilities, a comprehensive evaluation system for energy regulation capacity is constructed. This system takes the reservoir regulation performance and control capabilities as the core criterion, encompassing 14 specific indicators. By combining subjective weighting via the analytic hierarchy process and objective weighting using the critera importance through intercriteria correlation（CRITIC） method, the degree of affiliation for each indicator is calculated to form a comprehensive score for the energy regulation capacity of hydropower stations. An empirical study is conducted on five hydropower stations located in a prefecture-level city within Hunan Province. The evaluation results reveal that two stations reach excellent ratings and three are deemed qualified, which validates the applicability and effectiveness of the evaluation system and can provide quantitative decision support for the refined management of small and medium-sized hydropower stations in Hunan.
