Prevention of Unintentional Islands in Power Systems with Distributed Resources
Publicly accessible
License
This resource examines the phenomenon of unintentional islanding when a portion of the grid continues to be energized by distributed energy resources during a larger outage. It describes potential risks to safety and equipment, reviews existing standards and detection methods, and presents strategies for prevention, such as anti-islanding protections, relay settings, and inverter functionalities. The resource aims to inform utilities, regulators, and DER owners about best practices to ensure safe and reliable grid operation.
