The application discloses a method and device for evaluating a routing scheme of a power communication network. The application firstly constructs an information flow routing matrix based on the set routing scheme, and secondly sets a communication network failure matrix; and judges that each information flow is under the influence of a failure. reachability; calculate the routing vulnerability score of the information system under the failure of the communication network, so as to use the obtained routing vulnerability score to evaluate the pros and cons of the routing scheme, and realize the quantitative evaluation of the vulnerability of the routing scheme, which solves the current The evaluation work of the power communication network routing scheme is based on the dispatcher's judgment based on experience, and the evaluation result is easily affected by the dispatcher's subjective cognition, which leads to the technical problem that the accuracy of the evaluation result of the existing power communication network routing scheme is unstable.
Description
technical field [0001] The present application relates to the technical field of power communication, and in particular to a method and device for evaluating a routing scheme of a power communication network. Background technique [0002] The rapid development of the smart grid makes the current power system highly dependent on the optimal scheduling and control of various advanced information systems such as energy management systems and wide-area measurement systems, thus forming a power cyber-physical coupling system. As the coupling degree increases, the disturbance on the information side will have a non-negligible impact on the power system. Under different routing schemes, information flow is affected differently by communication network failures. Considering the characteristics of information-physical coupling, different routing schemes are affected by communication network failures on physical power grids differently. [0003] The current power communication networ...
