Problems solved by technology

These evaluations are related to a certain aspect or several aspects of the power grid, and most of them are evaluated in qualitative language, lacking a certain theoretical basis, and the evaluation results are too subjective and rough, which makes the evaluation results greatly discounted

Abstract

The invention, which belongs to the power grid field, relates to a risk assessment and assistant decision-making method and system for the regional grid operation. The method comprises: S1, acquiringrelated information of a grid as an input condition; S2, searching for a weak point of the grid and providing a possible accident analysis result and a corresponding processing measure and advice based on quantitative classification of a risk evaluation index; and S3, generating a risk assessment report to assist in the analysis of a grid operation risk, carrying out visual displaying, and carrying out a graphical simulation operation. According to the invention, the weak point of the grid is searched quickly by using the related information of the grid mode as the input condition, the possible accident analysis result as well as the corresponding processing measure and advice is provided, and the risk assessment report is generated to help the dispatcher analyze the grid operation risk. Therefore, quasi-synchronous safety assessment of the grid operation mode is realized; the workload of the operation dispatcher is reduced substantially; the risk assessment integrity and accuracy areimproved; and the power supply reliability of the grid is enhanced.

Description

technical field [0001] The invention belongs to the field of power grids, and relates to a method and system for risk assessment and auxiliary decision-making of regional power grid operation modes. Background technique [0002] In recent years, major power outages at home and abroad have occurred frequently. These major accidents have had a major impact on social development and suffered huge economic losses. The scale of the modern power system is constantly expanding, the structure is becoming more and more complex, and the reform of power marketization is deepening, which puts forward higher requirements for the safety of power grid operation. For this reason, various countries have proposed corresponding operation safety index systems, such as the United States put forward the AMI-SEC system security requirements, and the NERCCIP002-009 standard (network security standard for large power systems); The corresponding basic concepts and guiding principles are put forward;...
