The invention provides a method for modeling the risk assessment of electric power operation, which comprises the following steps: S1, risk consequence C modeling; S2: risk probability P modeling; S3:modeling the scoring system according to the risk consequence C and the risk probability P, and obtaining the electric power operation risk evaluation. In accordance with the prior art, the inventionmodels the risk consequence by using the analytic hierarchy process and the fuzzy comprehensive evaluation method, models the risk probability by using the function fitting algorithm based on the sample characteristics, and finally obtains the scoring system by the way of the nonlinear function assignment, thereby obtaining the electric power operation risk to be more comprehensive and reliable,and the accuracy is greatly improved.
