Quantitative assessment method of power grid disaster response capability based on fuzzy comprehensive evaluation and comprehensive weight¹

To study the objective assessment of power grid disaster response capacity under extreme natural disasters, a quantitative assessment method of power grid disaster response capacity based on fuzzy comprehensive evaluation and weight is proposed. Firstly, a pre-disaster endurance and post-disaster resilience evaluation index system is established by analyzing the comprehensive data of the power grid system. Then, the analytic hierarchy process and the entropy weight method to obtain the subjective and objective weights of the indicators are used and combined into comprehensive weight determination indicators. Fuzzy comprehensive evaluation to quantitatively evaluate the disaster response capability of the power grid is used. Finally, the proposed evaluation method is verified through a calculation example. The results show that the method is reasonable and effective, and has a certain guiding role for the grid to respond to extreme natural disasters.
