Voltage Cooperative Loss Reduction Strategy of Distribution Network with DG and EV

The uncertainties and randomness of distributed generators and electric vehicles connected to the power grid bring great challenges to voltage regulation and loss reduction in distribution networks. The paper proposed a distributed voltage drop together control algorithm, which without destroying current transformer capacity or for on-load tap-changer is the traditional voltage under the condition of pressure control device, by stimulating the converter between distributed generators and electric vehicles and grid, distributing the surplus reactive power from the distributed generators and electric vehicles, for voltage regulation and the line loss reduction. Under the condition of insufficient reactive power regulation, an active power reduction strategy of distributed generators was proposed to reduce the loss. Finally, the IEEE33 distribution system was taken as an example to verify that the proposed method can effectively carry out loss reduction and voltage regulation in the distribution network.
