Abstract：With the intensification of the global energy crisis and environmental issues,risk management of physical grid assets has become a key challenge for ensuring the stable operation of power systems.To address the complex risks faced by these physical assets,this paper proposes a comprehensive evaluation method that integrates the Fuzzy Analytic Hierarchy Process(FAHP),the Entropy Weight Method(EWM),and the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS).The method analyzes risk factors from three dimensions:technical,economic,and environmental,establishing a multi-level and multi-indicator evaluation system.First,the FAHP is used to determine the subjective weights of the risk factors,followed by weight adjustments through the EWM.Finally,TOPSIS ranks and analyzes the impact of each risk factor.The research results show that environmental risks play a dominant role in the risk profile of physical grid assets,and a series of targeted mitigation measures are proposed,providing scientific support for grid enterprises'risk management efforts.
