Prediction method and system based on power grid load

The invention discloses a power grid load-based prediction method and system, and relates to the technical field of power grid load prediction, and the method comprises the steps: carrying out the statistical analysis of load data of a target region, evaluating a power grid load prediction situation value of the target region, carrying out the statistics of meteorological data of the target region in an estimated power demand period, and carrying out the analysis, therefore, the meteorological interference index of the target area in the estimated power demand period is evaluated, the power supply fit index of the target area is obtained through data integration processing analysis, and power supply alarm prompt is carried out. According to the method, the power supply fit index of the target area is obtained by analyzing the load data of the power grid and the meteorological data, the accuracy and adaptability of power grid load prediction can be improved, the requirements of a power system are met, the avai
