Cyber Contingencies Impacts Analysis in Cyber Physical Power System

摘要

In a cyber-physical power system (CPPS), the interaction between the power cyber system and the power physical system becomes more extensive and more in-depth. For the purpose of analyzing the impacts of cyber contingencies on the power physical system concerned, a CPPS dynamic interactive model is proposed. In this model, the physical part of a radial power distribution system with distributed generators integrated is formulated as a typical differential-algebraic equation set, and the cyber part is described utilizing an incident matrix model, with multiple types of cyber contingencies in the information transmission process considered, including data misplacement, data termination, abnormal transmission delay and transmission error. The feasibility and effectiveness of the proposed method are demonstrated by a revised version of the IEEE 33-bus radial power system.
