Abstract

The invention discloses a power system load fluctuation analysis method, a device and a readable storage medium. The method discloses in the invention comprises the steps of firstly, establishing a load prediction model of a power system according to the historical load data of the power system and the historical data of a plurality of related factors; sequentially determining the corresponding data of the plurality of related factors in two selected dates through a control variable method, and inputting the data into the load prediction model, so as to obtain prediction load data corresponding to each related factor of the power system; according to the difference value of each prediction load data relative to an obtained actual load data, obtaining a load prediction variation quantity corresponding to each related factor; finally, carrying out load fluctuation analysis on all obtained load prediction variation quantities, so as to obtain the influence of each related factor on the load fluctuation of the power system. According to the method, the load fluctuation reason of the power system can be accurately analyzed.

Description

technical field [0001] The present invention relates to the technical field of power system load analysis, in particular to a power system load fluctuation analysis method, device and readable storage medium. Background technique [0002] Accurate power system load forecasting is an important prerequisite for the power system to reasonably arrange power generation, transmission, distribution, and use. The load forecasting technology of the power system is directly used in scenarios such as arranging power dispatching plans and conducting grid safety checks. The accuracy of forecasting It directly affects the safety and economy of the power system. Therefore, improving the load forecasting accuracy of the power system is the basis for realizing the refined management of power system economic dispatch. [0003] A comprehensive grasp of the load change law of the power system can improve the load forecasting accuracy of the power system, and by analyzing the reasons for the lo...
