Islanding phenomenon is undesirable because it leads to a safety hazard to utility service personnel and may cause damage to power generation and power supply facilities as a result of unsynchronized re-closure. …
Photovoltaic (PV) systems are semiconductor devices that use renewable solar energy to create electricity (see Photovoltaic (PV) systems). Most grid-tied PV systems connect to the traditional centralized grid or macrogrid and loose power whenever the large-scale electric power system goes down. [2]
Anti-islanding protection plays a major role in grid-connected inverters which are based either on solar PV or other renewable energy resources when they are connected to the utility. In this study, six grid-connected string inverters were characterized based on the Indian standard IS 16169:2019. This paper presents the real-time simulation …

On the one hand, it will enable you to continue to power your home with locally-produced solar generation even in the event of a grid outage. On the other hand, an islanded system has no risk of pushing excess electricity onto the grid, making it safe for utility workers to work to restore regular service.
