Abstract:Operational reliability of integrated energy systems pays more attention to the time-varying reliability under real-time operating conditions. The operational reliability assessment of integrated energy systems can not only realize the real-time reflection of operational status, but also predict the operational risks in a short period of time in the future under the premise of considering multiple operational uncertainties. The integrated energy systems involve various energy links, and there are problems of coupling between different energy sources. The factors affecting operational reliability are extremely complex and diverse. In order to avoid short-term operational risks and improve the safety and reliability of integrated energy systems, the modeling and assessment of operational reliability are of great significance. In this paper, firstly, the research status of model-driven equipment operational reliability modeling methods of the integrated energy systems was summarized. Then, the current research status of model-driven integrated energy systems operational reliability assessment was introduced in detail from three aspects such as system state generation and selection, system state analysis and assessment, and reliability indices establishment and calculation. In addition, the shortcomings of existing research were systematically summarized for reference and improvement in follow-up research.
