A New Approach to Anti-Islanding: Deployment Examples

Abstract

Islanding of Distributed Energy Resources (DER) is a growing concern as penetration increases. In a companion paper entitled “A New Approach to Anti-islanding: Design, Installation and In-Service Experience”, the authors describe a protective concept, DG Permissive (DGP), that reliably detects and removes an island within the 2 second window prescribed by the IEEE-1547 interconnection standard, regardless of penetration level. This paper provides examples of such a DGP system deployed in a wide range of DER applications.
