This paper presents the power management scheme for a power electronics based low voltage microgrid in islanding operation. The proposed real and reactive power control is based on the virtual frequency and voltage frame, which can effectively decouple the real and reactive power flows and improve the system transient and stability performance. Detailed analysis of the virtual frame operation range...
Power electronics technology is becoming an increasingly important aspect of today's power distribution system. It is the key interface to connect distributed energy resource (DER) to the utility and the local loads. With the increased penetration of power electronics based distributed generation (DG) systems, the power quality requirements are becoming more stringent. On the other hand, if controlled...
This paper presents the power management scheme for a power electronics based low voltage microgrid in islanding operation. The proposed real and reactive power control is based on the virtual frequency and voltage (??'-E') frame, which can effectively decouple the real and reactive power flows and improve the system transient and stability performance.
