Novel optimal coordinated voltage control for distribution networks using differential evolution technique

Abstract

This paper investigates a Distributed Generators (DG) connected to distribution net-work offering multiple benefits for grids and environments in the case of renewable sources used. Nevertheless, this task requires an appropriate planning and control strategy, if not several drawbacks can issue including voltage rise problems and increased power losses. To overcome such disadvantages, this paper proposes a coordinated voltage control CVC method for distribution networks with multiple distributed generators. This new method is based on a differential evolution DE approach to obtain the optimal setting points for each control component. Furthermore this proposed method considers both of time-varying load demand and production, leading to not only an improvement in the voltage profile but also to optimally minimizing the active power loss.
