Impact Analysis of Energy Supply Reliability of a New Generation Cyber Physical Energy System Considering Multivariate Information Disturbance

Abstract

In the context of the continuous deepening of energy Internet construction, the coupling degree between information systems and energy supply systems is deepening. In view of the problems that the energy supply reliability of the energy system does not take into account the fault of the information system, and the influence of the fault of the information component on the reliability of the system is not quantitatively analyzed. This paper proposed a cyber physical energy system reliability impact analysis method considering multivariate information disturbance. Firstly, the cyber physical energy system was taken as the research object, and the typical architecture of the cyber physical energy system was introduced. Secondly, the state model of the key equipment in the cyber physical energy system and the static connection and dynamic transmission model of the system were constructed. Besides, the operational characteristics and reliability evaluation indicators were put forward. Finally, the effectiveness and practicability of the proposed evaluation methods were verified by constructing practical cases, and the factors that affecting reliability were further analyzed.
