摘要
在能源互联网建设不断深入的背景下,信息系统与供能系统的关联耦合程度不断加深,针对目前评估能源系统供能可靠性未计及信息系统故障,且未量化分析信息元件故障对系统运行可靠性影响等问题,提出了考虑多元信息扰动的新一代信息能源系统供能可靠性影响分析方法。首先,以信息能源系统做为研究对象,介绍了信息能源系统的典型架构;其次,构建了信息能源系统内关键设备的状态模型以及系统的静态连接和动态传输模型;再次,提出了信息能源系统运行可靠性的评估指标及评估流程;最后,通过构建实际算例,验证了所提出评估方法的有效性和实用性,并进一步对可靠性的影响因素进行了分析。
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.
