Abstract: Because of the unstable balancing control of the ac side voltage by traditional methods, the power supply effect of the new energy distribution network is not ideal. Therefore, a new energy distribution net-work ac side voltage balance control method is proposed. The distributed data is used to mark the balance control target of the voltage on the ac side, and the range of control target is defined. With the help of the balance control algorithm, the ac side voltage in the new energy distribution network is balanced and controlled to realize the balance control of ac side voltage. The simulation results show that the distributed balance control method can enhance the stability of ac side voltage, guarantee the quality of power supply and be effective. The simulation results show that the distributed balance control method can enhance the stability of ac side voltage, guarantee the quality of power supply and be effective.
