Problems solved by technology

However, due to the excessive neglect of the physical characteristics of the power system by the complex network theory, it is still difficult to specifically guide the operation and control of the power system
[0005] At present, for the interactive influence of power communication, the problem of power system vulnerability detection method is that there is no mature power system vulnerability detection method that considers the influence of communication factors
The existing power system vulnerability detection methods lack the detection of the impact of communication faults such as delay, bit error and interruption in the power communication system on the power system, and cannot characterize the impact of communication on the power system

Abstract

The invention discloses a power system vulnerability detecting method based on power communication interaction. The method includes the following steps: step 10) building a power-communication composition system correlation matrix; step 20) measuring and calculating the power system vulnerability to obtain a power grid node vulnerability index and a power network branch vulnerability index; step 30) measuring and calculating communication business vulnerability, including a communication network node vulnerability index and a communication network branch vulnerability index; step 40) calculating power communication information interaction channel vulnerability; step 50) substituting the vulnerability indexes obtain from the step 20), the step 30) and the step 40) into the power-communication composite system correlation matrix to obtain the power-communication composite system vulnerability matrix, and sequencing the composite system vulnerability values from large to small. By means of the detecting method, the power system vulnerability can be accurately detected by combining the effect of the communication system on the power system.

Description

technical field [0001] The invention relates to the technical field of power grid security detection, in particular to a method for detecting the vulnerability of a power system based on the interactive influence of power communication. Background technique [0002] Vulnerability, also known as weakness or loophole, is a description of a system and its components that are easily affected and destroyed, and lack the ability to resist interference and restore the initial state. The vulnerability of the power system refers to the dangerous state of the power system where large-scale blackouts are latent due to factors such as human intervention, information, computing, communication, internal components, and protection and control systems. Power system vulnerability assessment mainly includes four aspects: event identification, risk calculation, network analysis and decision analysis. [0003] As China builds a strong smart grid with the UHV grid as the backbone grid and the c...
