Load Area application to radial distribution systems

Abstract

The evolution of the distribution systems involves updated and new control functionalities; along with them, a huge amount of information is made available and has to be handled. Actually, only part of this information is necessary; a remarkable simplification can be obtained by considering only the relevant information. For this scope, a method was recently proposed based on the concept of Load Area, a group of prosumers whose power injection has a similar impact on the distribution grid operating conditions. In this paper, the method previously developed for a generic distribution system is applied to a radial distribution system to obtain its equivalent radial representation; for it, the computational times for the power-flow problem are shown. The results confirm the viability of the method and the reduction of computational time for the ubiquitous power-flow problem.
