Under frequency load shedding technique considering event-based for an islanded distribution network / Erma Noraini Abdul Razak

One of the biggest challenges in an islanding operation is to reduce the power imbalance between dispatched power of Distributed Generation (DG) and load demand. A large power imbalance following islanding would cause under-frequency. Hence, an appropriate control is required to shed certain amount...
