Impacts of Cyber Contingencies on Cyber Physical Power Systems

doi:10.3969/j.issn.1000-7229.2018.06.012

Abstract

Abstract: ABSTRACT： In a cyber-physical power system （CPPS）, the interaction between the power information 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 dynamic interactive model is proposed for CPPS. 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, while the cyber part is described by an incident matrix model, with multiple types of cyber contingencies in the information transmission process considered, including data error, data mismatch and time delay. The feasibility and effectiveness of the proposed method are demonstrated by a revised version of the IEEE 33-bus radial distribution system.

Key words: KEYWORDS： cyber physical power system （CPPS）, cyber contingency, incidence matrix, distributed generator （DG）
