The invention relates to the technical field of power grid adjustment, and discloses an intelligent power grid adjustment method for electric vehicle charging load prediction analysis, and the method comprises the steps: carrying out the prediction of the charging time period and the charging amount of an electric vehicle for a user through combining the charging information data of the electric vehicle; calculating the charging concentration degree and the charging load of each charging station in different time periods; performing time period overlap ratio analysis on the charging concentration ratios of different time periods; and carrying out charging station charging strategy optimization in combination with the power grid load on the time periods of which the time period overlap ratio is higher than a preset threshold value. According to the method, the charging concentration ratios of different charging stations in different time periods are calculated by using the charging behaviors of the electric vehicle in each time period in each charging process, the time period overlap ratio analysis is performed on the charging concentration ratios of the charging stations in different time periods to obtain the time period with the maximum charging load, and the strategy optimization model is constructed by combining the power grid load to obtain the maximum charging load. The charging strategy of the charging station is optimized, the power grid load in a specific time period is reduced, and the power grid operation efficiency is improved.
