A method for identifying risk status of distribution network

Abstract

The invention relates to a method for recognizing a risk state of a power distribution network. The method is implemented by a serial computing method and a parallel computing method. In the serial computing method, risk state continuous recognition and tracking are performed after the risk state is recognized; in the parallel computing method, risk state continuous recognition and tracking and recognition of risk states of a power grid in various states and in each stage are performed at the same time; the serial computing method and the parallel computing method are different design ideas in the full power distribution network risk state recognition process, and the recognition results of the serial computing method and the parallel computing method are the same. By the method, judgment and evaluation of a risk index computing result are realized by adopting a design of a rule base, a knowledge base, a professional base and a risk base and online generation thereof, so that the risk state of the current power distribution network can be determined; due to the design of the rule base, the knowledge base, the professional base, a single and independent risk index for judgment is avoided and the judgment, the recognition and the evaluation of the risk state of the power distribution network are realized by adopting a comprehensive risk index.

Description

technical field [0001] The invention belongs to the technical field of distribution network analysis and control, and specifically relates to a risk state identification method of a distribution network. Background technique [0002] With the continuous growth of the economy, the society's demand for electricity is at a critical turning point. In the future, the scale of the distribution network will become increasingly large and the structure will become increasingly complex. While the rapid development of the distribution network has achieved great benefits, it has to bear greater potential risks. Especially with the access of distributed power in the power distribution system, the uncertain factors that are difficult for people to control and their impact on the power grid become more complex, which makes the planning and operation of the distribution network face great challenges. [0003] The risks existing in the operation of the distribution network include long-term...

Problems solved by technology

[0004] At present, the existing risk assessment methods are not enough to meet the accurate understanding and evaluation of the risk status in the operation, analysis and control of the distribution network, and the existing risk assessment research results are not enough to support the self-healing control of the distribution network. Accurate identification and tracking of network risk status
