Aiming at the influence of distributed power supply on the voltage and power distribution of distribution lines

a reactive power and voltage control method of 10 kV distribution network with distributed power supply is proposed. Firstly

the influence of the distributed generation on the voltage characteristics of the distribution network is analyzed. Then

a reactive power control method is proposed to balance the number of operation and optimization of the equipment. The control accuracy of the reactive power compensation equipment is optimized by dynamically adjusting the power factor and the frequent operation of the equipment is avoided. Finally

a decentralized and superior control method is proposed. The reactive power and voltage condition of the point are evaluated by detecting the grid connection of the distributed generation

and the difference is controlled according to the different voltage level. The simulation results show that the double reactive power control method proposed in this paper can significantly reduce the active loss and improve the voltage pass rate.
