Problems solved by technology

[0004] However, among the above-mentioned various systems, a small disturbance of one system will cause the failure of other systems, thereby affecting its own
For example, the 2003 Italian blackout was caused by the failure of a power station, which caused many power nodes to be disconnected from the power network, which in turn caused the failure of the communication network, which eventually caused the system to fail to work properly.
At present, there is no effective method to detect the vulnerability of interdependent network systems

Embodiment Construction

[0024] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0025] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

The invention provides an adjacent matrix based dependent network system and a frangibility detection method thereof. Network structure information of the dependent network system is expressed by an adjacent matrix, and the dependent network system comprises a first network which is a weighted network and a second network which is an un-weighted network; in each of the first and second networks, nodes are connected by connecting sides to express connection relation between the internal nodes; and between the first and second networks, cross-network nodes are connected by dependent sides to express the dependent relation between the network nodes. Thus, the frangibility of the dependent network system can be detected effectively.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to an adjacency matrix-based dependent network system and a vulnerability detection method thereof. Background technique [0002] With the rapid development of science and technology, the coupling and dependence between various infrastructures have become more and more important, such as the inter-city water supply system, power system, and communication An interdependent network system is formed among the infrastructure systems of power system, power system, and communication system. [0003] Taking the dependency relationship between the power system and the communication system as an example, the power system needs the communication and scheduling of the communication system, and the communication system needs the power support of the power system. The similar situation also has the power system and the railway transportation system, and so on. [0004] However, among the a...
