Reactive power compensation for parallel inverters without control interconnections in microgrid

In this paper, a control technique is developed for parallel inverters with no control interconnections in microgrid. The proposed control technique, based on droop control method and virtual impedance method, uses only locally measurable feedback signals to make some of the parallel inverters supply only reactive power equally for loads while the others share only active power. Simulation results are provided to prove the validity of this approach.
