Natural disasters, terrorist attacks and blackouts in traditional distribution system lead to power interruptions for longer durations. Intentional islanding with proper coordination and control strategy can be a feasible solution for utilizing alternate power from Distributed Energy Resources (DERs) in the above circumstances. Different DERs such as low power thermal generators, rooftop Photo Voltaic (PV) system and multiple energy supply systems integrating natural gas and hydrogen are proposed in literature for power resilience in aftermath of natural disasters. On the other hand, Low Voltage DC (LVDC) in distribution system network has raised great interests in recent years due to rapid developments in power electronic devices and converters. In this paper, real-time working of intentional islanding algorithm for power resilience during natural disasters in a prototype distribution system with DERs and smart architecture is described. The paper involves smart distribution system realized in LVDC.

传统配电系统中的自然灾害，恐怖袭击和停电导致较长时间的电源中断。在上述情况下，使用适当的协调和控制策略的有意孤岛可能是利用分布式能源（DER）的备用电源的可行解决方案。文献中提出了不同的DER，例如低功率热发生器，屋顶光伏（PV）系统以及将天然气和氢气整合在一起的多个能源供应系统，以提高自然灾害后的电力恢复能力。另一方面，由于电力电子设备和转换器的快速发展，近年来配电系统网络中的低压直流（LVDC）引起了人们的极大兴趣。在本文中，描述了在具有DER和智能体系结构的原型分配系统中，自然灾害期间有意孤岛算法的电源恢复能力的实时工作。本文涉及在LVDC中实现的智能配电系统。
