Power Electronic Converters Enabling the Power Sharing Solution in LVDC Smart Grids for the new Energy Communities

Power electronic converters represent the core of LVDC smart microgrids. They realize the backbone of the power sharing among the end-users, from the renewable energy generation to the load clusters. A typical application of LVDC smart grids is a residential building, where multiple end-users can gather in an energy community. In this building, a renewable energy source provides the required power to the loads, according to power splitting algorithms. The power sharing among the end-users is made possible through a double stage control system: a general control enables the power allocation among the end-users, while the local control on each converter realizes the interconnection between the smart microgrid and the low voltage distribution grid. In this paper, all the power electronic converters enabling the power sharing solution in a LVDC smart microgrid for the new energy communities are described. The stability of the control system is also tested under several stressing scenarios.
