Problems solved by technology

[0006] (2) Insufficient consideration of risk factors affecting the assessment results, resulting in inaccurate risk assessment
Consequences and probabilities in risk assessment are required to be as accurate as possible. Factors that affect these two aspects include line status, equipment conditions, and weather. Although the degree of influence is different, ignoring any possible factors will affect the assessment. The result makes an impact

Abstract

The invention discloses a multi-dimensional power distribution network system operation risk level assessment system and method. The system comprises an establishment module, an analysis module and anassessment module. The establishment module is used for inputting all historical data according to dimensions to establish a risk assessment database; The analysis module is used for carrying out correlation analysis on all historical data with different dimensions in the risk assessment database to generate a correlation coefficient table; And the evaluation module is used for evaluating the risk level according to the risk evaluation database and the correlation coefficient table. The method is executed through the system, a risk assessment database is established according to all historical data of dimensions, correlation analysis is conducted on all the historical data of different dimensions to generate a correlation coefficient table, and finally the risk level is assessed accordingto the risk assessment database and the correlation coefficient table. According to the system and the method, factors in multiple aspects are integrated, the risk assessment of the operation of thepower distribution network is realized, and the assessment result is more accurate.

Description

technical field [0001] The invention relates to the technical field of analyzing characteristics of safe and stable operation of a distribution network, in particular to a multi-dimensional distribution network system operation risk level evaluation system and a method thereof. Background technique [0002] The safe and stable operation of the power grid has always been the ultimate goal of power construction. As an important link connecting the transmission network and users, the operation security of the distribution network is crucial to the safe and stable operation of the entire power grid. Therefore, evaluating the security of the distribution network is conducive to improving the weak links of the power grid to improve the reliability of power supply. Among them, the risk assessment of the distribution network is an important branch of the power system risk assessment, which is aimed at various uncertain factors in the operation of the power grid, and classifies and e...
