[0047] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0048] The gist of the present invention is that, through the analysis of the current short-term load forecasting method and actual demand, it is found that the existing short-term load forecasting methods have the problems of single forecasting method and low forecasting accuracy. The present invention provides a frequency domain based Decomposition and short-term load forecasting method of artificial intelligence algorithm to solve the above problems.
[0049] see figure 1 , the load sequence is inherently unstable, and after frequency domain decomposition, part of the load sequence shows certain regularity. In order to improve the prediction accuracy, different prediction methods are used according to different characteristics. The core part of ...
