The invention provides a method for analyzing and evaluating electricity utilization safety risk evolution of a user in a severe weather. The method comprises the following steps that power distribution network connection relation data and reliability parameters of a power distribution network power device are input; a fuzzy set model of the power distribution network power device is established; a state transition matrix and a Markov chain equation are established and an initial value of the Markov chain equation is given; a time evolution rule of electricity utilization safety risks of the user in the severe weather is obtained. According to the method for analyzing and evaluating electricity utilization safety risk evolution of the user in the severe weather, the fuzzy set model, related to the user, of the device failure rate and the device repair rate in the severe weather is established, the method is applied to the fuzzy Markov process for evaluating time evolution characteristics of the electricity utilization safety risks of the user, the time evolution rule of the electricity utilization safety risks of the user in the severe weather is obtained, and therefore the load point power failure risk is researched in a dynamic aspect.
