In recent years, the penetration of distribution generations (DGs) has increased. Also the role of distributed generation has significantly increased not only as power generator, but also as an important factor in power quality improvement. In this paper, a method is proposed for reducing the voltage unbalance while the DG is not connected to the grid. Control loops pertaining to voltage and frequency powers are provided in order to control the voltage and frequency of local load. Besides, the virtual impedance loop and proportional-resonant controller are also utilized in the control loop. The simulation results confirm the functionality of the control strategy and the controllers in eliminating the imbalance.
