Abstract

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 utilized in the case of distribution networks, probability of their convergence would be low. Therefore, due to inherent characteristics of distribution networks, it is essential to develop distribution version of load flow methods. Distribution networks usually have single source node and they have a radial configuration, but sometimes there are one or multiple Dispersed Generation (DG) units supplying a fraction of the distribution feeder loads. Unlike transmission systems, there might be some unbalanced loads along distribution networks. This paper presents a load flow method for unbalanced distribution networks, which can handle the presence of DG units on the distribution networks, in various operating modes.
