Power Flow Analysis on AC And DC Transmitting Concurrently Along the Same Feeder Line in Distribution Network

In this paper, the idea that the DC generated by distributed generation (DG) transmits concurrently with AC in the same feeder line in distribution network is presented. The basic concept and the circuit topology are also expressed. For the low capacity DG, it is proposed a concept of “suppositional stack bus” which is useful and convenient for AC and DC power flow computation. After decoupling AC and DC network at the place of “suppositional stack bus”, the computation turns to be simple and rapid. Case study shows that network loss is smaller and voltage is more balanced under this way. So the advantage of the operation as well as the availability of the calculation method is proved.
