Abstract
This paper proposes an impact strategy to curtail the reactive power imbalance in islanded microgrid which results in the maintenance of voltage balance. The reactive power imbalance compensation is achieved by injection of an accurate synchronous voltage supply into the microgrid through the power electronics based converters. This task is done by advanced Flexible a.c transmission system (FACTS) device connected with Unified power flow controller (UPFC) to the microgrid. This compensation reference is obtained through a synchronous voltage management, avoiding the load frequency control loop. This strategy does not need any hardware modification. This management strategy is simulated in Matlab/Simulink to prove its effectiveness.
