The invention discloses a micro-grid optimization operation method and system considering electric vehicle load demand response, and relates to the field of micro-grid optimization operation. The method comprises the following steps: predicting the traffic flow of each entrance and exit of a target highway section in an expressway based on historical traffic flow data and a probability model by using a Monte Carlo simulation method, and determining road section traffic flow prediction data of the target highway section; determining an electric vehicle charging demand of the target road section based on the road section traffic flow prediction data and the electric vehicle SOC distribution corresponding to the road section traffic flow prediction data; and in response to the charging demand of the electric vehicle, constructing a micro-grid optimization operation model of the service area and solving the micro-grid optimization operation model to determine an optimal optimization operation scheme meeting the load demand of the electric vehicle. A Monte Carlo simulation method is adopted to predict the traffic flow of each entrance and exit of the expressway based on historical traffic flow data and a probability model, and load demand response is adopted to finely guide the charging behavior of the electric vehicle, so that the optimized operation of the expressway microgrid is realized.
