Voltage unbalance compensation in an islanded Microgrid system by using negative sequence current feedback

Voltage quality problem has been raised a high concern of academic and engineering field. The voltage quality problem not only affect the performance of the equipment, but they also affect the normal operation of entire power system. In this paper, voltage unbalance compensation in an islanded micro...

Description
Summary:Voltage quality problem has been raised a high concern of academic and engineering field. The voltage quality problem not only affect the performance of the equipment, but they also affect the normal operation of entire power system. In this paper, voltage unbalance compensation in an islanded microgrid is considered. The Sensitive Load Bus (SLB) is located at the Point of Common Connection (PCC) of the Distributed Generators (DGs), where they are connected in parallel. To achieve more sharing accuracy, the negative sequence current feedback is needed in this circuit.
