Power load nonlinear harmonic comprehensive prediction method and device and storage medium

Abstract

The invention discloses a power load nonlinear harmonic comprehensive prediction method and device based on an artificial immune algorithm and a storage medium. The method comprises the steps that anAIS-based harmonic average comprehensive prediction model is established, the optimal weight of each single power load prediction model in the power load prediction comprehensive model is used as an antigen, the solution of the weight is used as an antibody, and the working principle of a biological immune system is simulated; obtaining a prediction result by using the following four models: a metering economic model, a stepwise regression model, a gray index smoothing model and a fuzzy clustering model; searching an optimal weight; namely, a globally optimal solution is searched and obtainedthrough the processes of antibody initialization, target function calculation, immune genetic evaluation, immune genetic operation selection, crossover, variation and the like. The method has high androbust information processing capacity, does not require the objective function to have derivable equal-height additional information when solving the problem, and is higher in efficiency in the search process.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a method, device and storage medium for comprehensive prediction of power load nonlinear harmony based on artificial immune algorithm. Background technique [0002] Load forecasting is the basis for power system planning, operation, and demand-side management. The level of power load forecasting has become one of the notable signs of whether a power company's management is moving toward modernization. Especially in today's unprecedented development of my country's electric power industry, power consumption management is coming to the market, and the problem of power load forecasting has become an important and arduous task we are facing. [0003] Although the research results of the forecasting methods in the prior art are relatively mature, various forecasting methods are proposed under certain assumptions, and often contain information independent of the system, ...
