Self-optimizing Droop Control and Quasi-Synchronization Strategy Based on Emergency Power Source

Aiming at the emergency power supplying measures in the case of large-scale power outage, this paper proposes a Self-optimizing Droop Control (SDC) method for Emergency Power Source (EPS) with self-adjusting time constant. Based on SDC method, an automatic quasi-synchronization strategy for EPS is designed. It can realize decentralized control and smooth networking of multiple EPSs, ensure reliable and uninterrupted power supplying for important loads, and reduce losses caused by disasters.
