A local real-time controller to face the problem of power imbalance in a VED consisting of several DC Microgrids

The paper aims to face the problem of real time power imbalance within a Virtual Energy District, including several DC Microgrids, using a local real-time control based on DC Bus Signaling approach. The attention on DC distribution is increased, in the last years, according to the increase of DC loads and DC output type energy sources such as Photovoltaic and energy storage systems. The control strategy is realized in a distributed and decentralized way. Several numerical tests have been provided considering a Virtual Energy District consisting of three Microgrids representative of three municipality buildings in South Italy. The entire system has been modeled in Ansys Simplorer environment and the simulation results demonstrate the efficacy of the proposed control approach.
