能量集线器是多载波能量系统中最重要的概念之一，它通过各种能量转换器和/或存储元件来接收、转换、存储和传递不同的能量载体。在多载波能源系统中，为了经济高效、可靠地向负荷供电，轮毂组成部件的选择（称为轮毂设计）及其运行问题具有重要意义。本文提出了考虑可靠性约束的能源枢纽优化设计与运行的综合线性化模型。检查了单一偶然性下的充分性指标和最大允许负荷损失概率（LOLP），并在优化过程中引入了不同的可靠性约束，以满足不同负荷类型的可靠性要求。最后，将该方法应用于考虑电负荷和热负荷的测试用例。仿真结果表明，该方法在满足能源需求的同时，能够满足可靠性约束。
An energy hub, which receives, converts, stores, and delivers different energy carriers by means of a variety of energy converters and/or storage elements, is one of the most important concepts in multicarrier energy systems. For cost-effective and reliable supply of energy to loads in multicarrier energy systems, the problem of selecting different components forming the hub (referred to as hub design) and their operation is of great importance. In this paper, a comprehensive linearized model for optimal design and operation of energy hubs considering reliability constraints is proposed. Adequacy indices and maximum-allowable loss of load probability (LOLP) in case of single contingency are checked and different reliability constraints are introduced in the optimization process to satisfy the required level of reliability for different load types. Finally, the proposed method is applied on a test case considering electrical and thermal loads. The obtained results show the ability of the proposed method in meeting energy demand while respecting reliability constraints.
