Abstract

Voltage plane disruption is one of the main problems encountered by distribution network operators due to the integration of dispersed generation . In this study, we approached this problem and studied its impact. We set up a nodal topological model for a simple radial feeder. This modelling, associated with a software application that we developed, provides an instantaneous voltage profile of the feeder, performs multi-criteria simulations, and improves this profile. Simulations showed that the integration of dispersed productions, within certain limits of injected power, solves end-of-feeder voltage drop problems. However, an integration rate that exceeds 35% of the installed power of the transformer causes over-voltages at certain injection points and degrades the voltage profile. By adjusting the on-load tap changer and reactive and/or active powers, the profile is improved in most cases. This multi-purpose project aims, among other things, to offer one of the most important elements of voltage regulation on the network in real time.
