Concurrent control of MV and LV networks for ancillary services provision

In many countries, in the last years, there has been a wide spread of Distributed Generation (DG) from renewable sources at MV and LV level. The distribution network is eventually changing from a passive structure to an active protagonist of a dynamic, low carbon and reliable energy market. On the other hand, this change could lead to a power quality depletion and to threats to the safety of the network itself. In this work, a concurrent control strategy is proposed to coordinate the prosumers with the aim of improving the reliability of the distribution network. The control scheme is based on an adaptive-area-based method and a multi-conductor Power Flow. In this way, it is possible to monitor the voltage unbalance among the phases while managing voltage and current magnitudes.
