摘要：

Communication system provides technical support for observability and controllability of Wide-Area Power System. However, communication faults such as time delay, bit error and interruption may lead to abnormal operations, sometimes even cause cascaded failure in electric power system. Therefore, it has practical value to perform the vulnerability assessment of electric power and communication system in order to provide early warnings and protect the vulnerabilities of system. To evaluate the influence of communication system for electric power system, an incidence matrix was proposed to represent the connection pattern of electric power system and communication system. Firstly, a static vulnerability matrix was established in this paper to evaluate the vulnerability of composite system at a particular time section. In order to do so, various methods were used like electrical dissecting algorithm, vulnerability index of communication system, as well as vulnerability of electric power communication service interaction. Next, the real-time vulnerability of composite system was updated based on the charge of electric power and communication state. Dynamic vulnerability matrix to evaluate the real-time vulnerability of composite system was established as a result at the end. The proposed method was presented and validated in this paper by using an example of a simple composite system. © 2015 Chin. Soc. for Elec. Eng.
