This paper give an introduction about the Active Network concept that can be managed by a multi-agent system (MAS). Voltage regulation, one of Active Network's services, is then presented. The autonomous voltage control within each feeder (Cell) can be deployed by a combination of active and reactive power supports of distributed generators (DG). The coordination voltage control defines the optimal...
Due to gradually increasing loads, medium voltage distribution feeders come closer to their voltage and current limits. Furthermore the introduction of distributed generation (DG) causes larger voltage variations. In this paper a control concept is proposed for so called intelligent nodes (INs) applied at medium voltage level. The IN has the potential to extend the power limits of feeders and to improve...
The increase of distributed power generation can result in equilibrium of local produced and consumed electrical energy. Power electronics and storage can transform networks in which such equilibrium exists into autonomously controlled networks. These networks remain part of the rest of the power grid. An example of such a network contains several MV feeders and their LV networks. One of the main...
The increase of dispersed generation (DG) has a strong impact on power system operation. A distribution network, where most of dispersed generators are connected, cannot be considered as passive anymore. Active character of the distribution networks brings problems and uncertainties, but at the same time offers more possibilities for control. Control of distribution networks with DG can be performed...
