The invention provides a regional power grid management method containing an electric vehicle charging load model, and the method comprises the steps: carrying out the partitioning and simplification processing of a regional power grid, and obtaining a plurality of regional power grid partitions; based on historical data of the regional power grid, a multi-stage fixed load demand curve is obtained through a system grading load model; based on the weather-daily mileage probability density function of the electric vehicle in the regional power grid, an elastic load demand curve is obtained according to an electric vehicle charging load model; determining a load demand horizontal curve of the regional power grid according to the multi-stage fixed load demand curve and the elastic load demand curve; performing partition simulation analysis on the plurality of regional power grids to obtain a failure load horizontal curve of the regional power grids; and obtaining the load expectation of the regional power grid according to the failure load level curve and the load demand level curve. According to the invention, the accuracy of regional power grid evaluation management is improved by considering the electric vehicle load level change influenced by weather.
