Abstract

The invention belongs to the field of big data, and particularly relates to an electric power system stability evaluation method and system based on big data analysis. The method comprises the following steps: S1, firstly, mutually connecting a plurality of power devices, carrying out power-on inspection, obtaining the state and data of a power system by using the power devices, carrying out matrix conversion on the state and data of the power system, and converting the state and data into a power system state data matrix; a plurality of power devices are connected to build a power system foundation, a power system state data matrix is obtained, the power system state data matrix is converted into a network model, weak load nodes in a power system are calculated, dimensionality reduction is carried out on the matrix, and physical attribute values are measured. The stability evaluation of the power system is realized by using the neural network model, the data transmission pressure is reduced, the evaluation efficiency is improved, and technicians can effectively analyze the system operation data.

Description

technical field [0001] The invention relates to the field of big data, in particular to a power system stability evaluation method and system based on big data analysis. Background technique [0002] With the large-scale access of flexible loads such as microgrids, non-industrial air conditioners, and interruptible loads, the power system has also been upgraded. [0003] The power system is an electric energy production and consumption system composed of power plants, power supply and distribution stations and other links. It performs stable transmission and control of electric power to ensure that users can safely use high-quality electric energy. [0004] With the advent of the era of big data, the intensity of power system operation has increased. Since the existing power system does not have a clear stability evaluation method and system for power system analysis based on big data, a method based on big data analysis is proposed to solve the above problems. Power system...
