Modeling, Measurement, and Risk Assessment of Nuisance Distributed Energy Resource Islanding

Anti-islanding protection or islanding detection for distributed energy resources have been extensively investigated and discussed in the past two decades. However, the following limitations in anti-islanding schemes still exits: 1) a gap still exists for synchronous generators, 2) degraded performance for inverter-based generators. Many proposed anti-islanding methods are not practical, as seen by utilities. This panel is intended to introduce these gaps, propose methods to manage risks inherent to methods, and present real case studies, which cover recent findings on distributed energy resource islanding detection performance from the field operation of photovoltaic power stations, farm biogas generators and other distributed generation units. The panel will bridge an industry knowledge gap in theory and application.
