Load flow method for distribution networks with multiple source nodes

The conventional load flow methods for transmission systems could not be utilized for distribution systems, due to their especial characteristics. If methods like Newton-Raphson and Fast-Decoupled are used for distribution systems, the probability of their convergence would be low. Therefore, due to inherent characteristics of distribution systems, it is essential to develop the distribution version of the load flow methods. The distribution networks usually have single source node and they have a radial configuration, but sometimes there are more than one source node that supplying the distribution network. This paper presents a load flow method for distribution networks, which can handle one or more sources on the distribution networks.
