Electric power material demand prediction system and construction method of electric power material demand model

Abstract

The invention provides a construction method of an electric power material demand model. The construction method comprises the steps of S1, obtaining electric power material whole-process data; s2, constructing and forming a multi-level comprehensive electric power material demand prediction model by utilizing the electric power material whole process data obtained in the step S1 and adopting a mode of combining a least square support vector machine, an echo state network and a regularization extreme learning machine, and the method comprises the following steps: S21, establishing a sample database; s22, adopting a least square support vector machine to predict the electric power material demand; s23, adopting an echo state network to predict the electric power material demand; s24, adopting a regularization extreme learning machine to predict the electric power material demand; and S25, integrating and weighing the prediction results to obtain a final prediction result of the electricpower material demand. Meanwhile, the invention provides an electric power material demand prediction system. The system comprises the electric power material demand model constructed by the method.The method effectively improves the perspectiveness of material management of a power grid company, creates favorable conditions for an enterprise to extract overall resources, guarantees the operation reliability support of a power grid, and reduces the operation cost of a power grid enterprise.

Description

technical field [0001] The invention relates to the technical field of power system material management, in particular to a power material demand forecasting system and a method for constructing a power material demand model. Background technique [0002] Electric power is the basic pillar industry of the national economy. The development of various industries and the growth of my country's economy are closely related to electric power. Once an accident occurs in a substation or a power transmission and distribution line, it will affect the stability of the power grid and cause a large-scale power outage, which will affect the reliability of power supply and cause users serious damage. Therefore, the normal construction and operation of the power grid is the basis for ensuring the normal life of the people and the normal activities of the country. [0003] Power materials are the basic guarantee in the process of power grid construction. The quality of their materials is not ...
