Urban power grid emergency capacity assessment method

The invention discloses an urban power grid emergency capacity assessment method and belongs to the technical field of electrical power system emergency. The urban power grid emergency capacity assessment method comprises the steps of utilizing an anti-entropy weight method to calculate objective weights of emergency capacity assessment indexes of all levels of urban power grids, utilizing a G1 method to calculate subjective weights of the emergency capacity assessment indexes of all levels of urban power grids on the basis, and linearly combining the subjective weights and the objective weights to obtain combined weights of the emergency capacity assessment indexes of all levels of urban power grids, wherein the disadvantage of the limitation of solely subjective weight calculation or solely objective weight calculation is successfully overcome, and the accuracy of the weight calculation is improved; utilizing fuzzy comprehensive judgment to perform initial judgment on the urban power grid emergency capacity, utilizing a grey relational degree method to correct an initial judgment result, performing final judgment on the urban power grid emergency capacity to confirm the urban power grid emergency capacity level. The urban power grid emergency capacity assessment method well masters the situation of the urban power grid emergency capacity and has important practical significance on perfection of the urban emergency capacity promoting work.
