Power Flow Calculation of Distribution Network with DG Based on Advanced Forward and Backward Substitution Algorithm

Compared with the traditional power system, there are some differences in the aspect of distribution network structure, line parameters and load parameters in the power system with distributed generations. Therefore, the conventional power flow algorithm can not be applied to this kind of networks. Considering that the distributed generations have special influence on the operation of distributed network, a novel power flow calculation method for this kind of distribution network is studied in this paper. Several equivalent circuit models of distributed generations and the corresponding approaches have been researched. The feasibility of this proposed power flow algorithms can be verified through the program designed in Matlab software.
