| Abstract |
To achieve both network losses reduction and voltage regulation, a reactive power voltage control method is proposed, which is based on the point of common coupling (PCC) voltage and the active power of renewable generators (RGs). The proposed method utilizes the voltage at the PCC and the active power output information, which enables improved voltage regulation capability while reducing network losses. The proposed reactive power control method was simulated using actual solar power output data in a radial feeder model with multiple RGs connected. The simulation results show that the proposed control strategy maintains the grid voltage within the normal operation range and the network losses are less than the conventional control strategies. |
