Load Flow Method for Distribution Network Design by Considering Committed Loads

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 the 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. One of the applications of distribution load flow methods is in the design process, at either MV or LV level. There are two types of loads in the design process, current committed and demand committed loads that both must be considered by load flow for design purpose. This paper presents a load flow method for distribution network design, which can handle both current and demand committed loads
