一种应对输配电网中网络-物理异常的新型电网韧性框架

With the advancement of smart grid technologies and the increase in renewable energy resources in bulk transmission and distribution grids, the dependency on measurement-based smart devices and cyber resources has increased significantly. This development has heightened the cyber-physical vulnerabilities of the grid, raising concerns about system resiliency, potentially leading to power interruptions and widespread blackouts. In this paper, a novel integrated transmission & distribution (T&D) resilient grid framework is proposed to enhance grid resiliency during cyber-attacks and abnormal grid events (faults, line outages, generator outages, etc.) that incorporate anomaly detection (grid events/cyber-attacks), islanded resilient operation, fault ride-through conditions, networked microgrid operation, attack mitigation and resynchronization to the main grid. Simulation results show robust and resilient grid operation even with forced islanding of a particular region after the occurrence of grid anomalies.
