I. Introduction
Electric power industry is an important energy basic industry in China, which relates to the development of national economy. The development and construction of the electric power industry are related to the development of various industries in the country. In recent years, the installed capacity of generators in China is constantly expanding, and the power grid is constantly developing and constructing, especially the development of smart grids has made the changes in electricity load more complicated. Electricity companies are facing greater challenges and need to predict loads more accurately in order to make reasonable power scheduling and resource allocation. Therefore, it is more and more important to study the electricity load prediction. Only by conducting comprehensive and detailed research on the data related to load prediction and formulating efficient and economic power generation plans, the electricity sector can continue to provide users with safe and reliable power energy, ensure the safe and stable operation of the power system, reduce power generation costs and improve economic benefits [1] [2].
