Abstract

The invention provides a power grid state prediction method and prediction system based on edge calculation, which belong to the field of electrical engineering science. Accurate prediction of a powergrid state is realized by establishing a multi-source data-driven power grid state prediction model. The method specifically comprises the steps of through effective utilization of edge nodes, realizing on-site management and control and analysis of power grid data; optimizing a BP neural network model through a genetic algorithm established on an edge layer; and training historical data of the power grid to realize prediction and evaluation of the state of the power grid. An edge calculation module is introduced into an electrical system, and the physical distance between a data source and aprocessing source is shortened, so that the data volume and time delay in the transmission process are reduced, and data analysis and processing are completed quickly.

Description

technical field [0001] The present invention relates to the field of electrical engineering science, in particular to a grid state prediction method and system based on edge computing. Background technique [0002] In the work report, the State Grid Corporation put forward the requirements for establishing the ubiquitous power Internet of Things, pointing out that the ubiquitous IoT sensing technology can endow the power system with the capabilities of dynamic flexible perception, real-time communication, intelligent control and reliable information security. Systematic monitoring and management offers new opportunities. On the one hand, the application of Internet of Things technology realizes the connection between people and things, and between things and things, and realizes the panoramic monitoring of power grid status and the effective transmission of information [1]. On the other hand, the access of a large number of terminal devices causes massive redundant data to ...
