Abstract

The invention discloses an application method for artificial intelligence in seasonal load prediction. The application method comprises the steps of: acquiring meteorological load data based on a method class of eliminating trend loads, acquiring a linear trend load function through least square fitting, and subtracting the trend loads from an original load sequence to serve as meteorological loaddata; then performing clustering analysis on the sample data by applying an FCM clustering algorithm so as to obtain three different types of training samples in total; then establishing a temperature correction model, wherein temperature correction needs to be conducted on the highest temperature of the high-temperature weather in consideration of the air temperature accumulation effect of the high-temperature weather in summer; and establishing a PSO-ELM load prediction model, wherein a particle swarm optimization algorithm (PSO) is combined with an extreme learning machine (ELM) to effectively improve the load prediction precision. Thus, an important practical application value is achieved.

Description

technical field [0001] The present invention relates to the technical field of meteorological load forecasting, in particular to an application method of artificial intelligence in seasonal load forecasting, Background technique: [0002] A large number of studies have shown that the relationship between temperature, humidity, wind and other meteorological factors and short-term load changes of electricity is particularly important. The most critical meteorological factor is temperature change, followed by humidity, wind and other factors. With the development and improvement of my country's social and economic level, more and more refrigeration and heating equipment have entered the lives of residents. The increase in the proportion of these temperature-sensitive loads in the total power load will have a significant impact on the power system. Summer cooling loads, The heating load in winter will be directly affected by meteorological factors. For example, rainfall will dire...
