Abstract: In the context of the continuous deepening of energy Internet construction, the degree of coupling between information systems and energy supply systems is deepening. Current assessment of energy supply reliability does not include information system failures, and the impact of information component failures on the operational reliability of the system is not quantified. This paper proposes a new analysis method for energy supply reliability considering multi-information perturbation. Firstly, the cyber physical energy system is taken as the research object, and the typical architecture of the system is 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 are constructed. Thirdly, the evaluation indices and evaluation process of the operational reliability of the cyber physical energy system are proposed. Finally, the validity and practicability of the evaluation method proposed in this paper are verified by constructing practical cases, and the factors affecting reliability are further analyzed.

Key words: cyber physical energy system, information disturbance, reliability, impact analysis
