Coordinated control of distributed energy resources and flexible links in active distribution networks

Active distribution networks (DNs) have to integrate a high level of distributed energy resources (DER). Using the classical control strategies, such amount of DER results in overvoltages and lines saturations across the system. To overcome these problems, a new control approach in the DMS is presented in this paper. This approach consists on using the DER reactive power capability and coordinate them with flexible links which can virtually mesh the naturally radial DN. The proposed control relies on an optimization problem which decreases the system losses and improves the voltage profile.
