Load Flow Method for Distribution Networks with Automatic Power Factor Controller

Inhalt:
The conventional load flow methods for transmission systems could not be utilised 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 will 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 one or multiple power factor controllers to improve the power factor along the feeder. This paper presents a load flow method for distribution networks, which can handle the presence of power factor controllers on the distribution networks, in various operating modes.
