This paper aims to propose a comprehensive energy management system (CEMS) to simultaneously enhance the resilience of microgrids (MGs) and distribution network (DN) in a multi-microgrid (MMG) system against unexpected events. It also develops a reliability evaluation framework for the reliability evaluation of MMG distribution systems. In this regard, the proposed CEMS includes two main strategies: (1) networked operation mode (NOM), attributed to the cooperation of independent sub-sections (MGs/DN) in fault-affected portions. Here, each MG must exchange power with the DN and other MGs (may be islanded simultaneously) by participating in peer-to-peer (P2P) energy sharing to enhance resilience and reliability of the whole network, and (2) individual operation mode (IOM), comprising the grid-connected, optional islanding, fully forced islanding, and partial islanding modes for different operational requirements of MGs. Thus, the required information of an outage is identified. A suitable decentralized strategy based on the proposed CEMS and the novel adaptive problem formulation are initially used to operate such systems under different operating conditions. The NOM and IOM together assure the survivability of the whole system during the emergency periods and maintain reliable electric power supply for consumers while guaranteeing system stability indicators and ensuring operating costs of MGs. To substantiate these claims, we use different case studies to demonstrate the efficiency of the proposed CEMS based on a modified reliability test system.

考虑对等能量共享的多微电网配电网可靠性导向运行

本文旨在提出一种综合能源管理系统 (CEMS),以同时增强多微电网 (MMG) 系统中微电网 (MG) 和配电网络 (DN) 对突发事件的恢复能力。它还为 MMG 配电系统的可靠性评估开发了一个可靠性评估框架。在这方面,所提出的 CEMS 包括两个主要策略:(1)网络运行模式(NOM),归因于故障影响部分中独立子部分(MG/DN)的合作。在这里,每个MG必须通过参与点对点(P2P)能量共享与DN和其他MG(可能同时孤岛)交换功率,以增强整个网络的弹性和可靠性,以及(2)单独运行模式( IOM),包括并网、可选孤岛、完全强制孤岛,和部分孤岛模式满足 MG 的不同操作要求。因此,确定了中断所需的信息。基于所提出的 CEMS 和新颖的自适应问题公式的合适的分散策略最初用于在不同的运行条件下运行此类系统。NOM和IOM共同保证了整个系统在紧急情况下的生存能力,在保证系统稳定性指标和保证MG运行成本的同时,为消费者保持可靠的电力供应。为了证实这些说法,我们使用不同的案例研究来证明基于改进的可靠性测试系统的拟议 CEMS 的效率。基于所提出的 CEMS 和新颖的自适应问题公式的合适的分散策略最初用于在不同的运行条件下运行此类系统。NOM和IOM共同保证了整个系统在紧急情况下的生存能力,在保证系统稳定性指标和保证MG运行成本的同时,为消费者保持可靠的电力供应。为了证实这些说法,我们使用不同的案例研究来证明基于改进的可靠性测试系统的拟议 CEMS 的效率。基于所提出的 CEMS 和新颖的自适应问题公式的合适的分散策略最初用于在不同的运行条件下运行此类系统。NOM和IOM共同保证了整个系统在紧急情况下的生存能力,在保证系统稳定性指标和保证MG运行成本的同时,为消费者保持可靠的电力供应。为了证实这些说法,我们使用不同的案例研究来证明基于改进的可靠性测试系统的拟议 CEMS 的效率。NOM 和 IOM 共同保证整个系统在紧急情况下的生存能力,在保证系统稳定性指标和确保 MG 的运行成本的同时,为消费者保持可靠的电力供应。为了证实这些说法,我们使用不同的案例研究来证明基于改进的可靠性测试系统的拟议 CEMS 的效率。NOM和IOM共同保证了整个系统在紧急情况下的生存能力,在保证系统稳定性指标和保证MG运行成本的同时,为消费者保持可靠的电力供应。为了证实这些说法,我们使用不同的案例研究来证明基于改进的可靠性测试系统的拟议 CEMS 的效率。
