Abstract
Aiming at the influence of distributed power on the voltage of distribution lines and power flow distribution, a method containing reactive voltage control for 10kV distribution network with distributed power supply is proposed. Firstly, the influence of accessing distributed power supply on the voltage characteristics of distribution network is analyzed. Then, a grid reactive power control method for balancing the operation times and optimization effects of equipment is proposed. The control precision of reactive power compensation equipment is optimized by dynamically adjusting the power factor, avoid the frequent operation of the equipment; finally, a decentralized and superior control method is proposed. By detecting the distributed power source's point of integration, the reactive power and voltage situations at the point are evaluated, and the differentiated control is performed according to different voltage levels. The simulation experiment results show that the proposed dual-layer reactive voltage control method can significantly reduce the active loss and improve the voltage pass rate.
