The transmission and distribution of electric power rely on complex, interconnected systems that can split into subsystems due to faults, maloperation, or targeted switching. This raises critical questions: Are these subsystems survivable? Are their sizes random or predefined? And under what conditions can they operate stably?
With the growth of renewable generation in distribution grids, local intended islands are increasingly feasible, but the likelihood of unintended islanding events also rises, necessitating careful monitoring and control. Despite growing academic discussion, no comprehensive reference has yet addressed the full scope of this topic.
Intended and Unintended Islanding of Distribution Grids fills this gap, offering a practical guide for researchers, industry professionals, and grid operators involved in building, extending, or maintaining electricity networks. Chapters cover power system dynamics and stability, grid connection point behavior, power system restoration, protection and islanding detection, planning for secure islanding, time-domain modeling of distribution grids, insular power systems, droop-based practical examples, bottom-up grid restoration, and management of unintended islanded grids.
