Coordination of voltage regulation in Active Networks

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 tap setting of the on-load tap changer (OLTC) while comparing amounts of control actions in each Cell. The test results show that the voltage regulation in Active Network can help to integrate more DGs and mitigate voltage violation effectively. The optimal solution can be reached within a small number of calculation iterations.
