摘要:
      随着能源互联网的发展和能源交互程度的加深,多能源集成耦合系统对供能可靠性提出了更高的要求。因此,量化不同能源之间的耦合逻辑关系,研究综合可靠性评估方法是目前亟待解决的重要问题。针对传统可靠性评估方法难以合理有效评估多能源耦合系统供能可靠性的问题,本文首先以综合能源微网作为研究对象,结合能源集线器模型构建了典型微网系统的物理模型;其次,建立设备元件的状态模型并梳理微网系统可靠性的评价指标;在此基础上,分析微网系统的运行机制与时序模型,并通过FMEA分析与蒙特卡洛模拟相结合的方法,分别建立了并网与电孤岛两种典型运行模式可靠性的评估模型,提出评估流程;最后,通过实际算例,评估综合能源微网年可靠性指标以及典型场景典型时段内预安排停运的可靠性,进一步说明本文所述内容的有效性与实用性。
Abstract:
      With the development of Energy Internet and the deepening of energy interaction, multi-energy coupling system put forward higher requirements for energy supply reliability. Therefore, to quantify the coupling logic relationship among different energy sources, it is an important problem to study the comprehensive reliability evaluation method. Aiming at the problem that traditional reliability evaluation methods were difficult to evaluate the reliability of the multi-energy coupling system effectively, this manuscript took multi-energy microgrid as the research object, and constructed typical physical model based on energy hub model. Secondly, the state model of equipment components and evaluation index of the reliability of multi-energy microgrid were established. On this basis, the operation mechanism and the time sequence models of multi-energy microgrid were analyzed, and the evaluation model of grid-connected and electric-isolated two kinds of typical operating mode were established respectively based on the method of combined the Monte Carlo simulation with FMEA, and put forward the assessment process. Finally, a practical example was given to evaluate annual reliability indexes of multi-energy microgrid and the reliability of the pre-arranged outage in the typical period of the typical scenario and the availability and practicability of the proposed method in this article was verified.
