This paper proposes the smart integration of Distributed Energy Resources (DERs) in microgrids through the use of Distributed Unified Power Quality Conditioners (D-UPQC). The proposed D-UPQC contains a PV and an Energy Storage System (ESS) and may be operated in grid connected, or in island mode, in case of grid failure. The control strategies are designed to guarantee that in grid connected mode...
Grid connected converters produce current harmonics, which need to be mitigated towards the grid. Passive output filters are the standard solution. Considering the growing count of low-power energy sources, the cost of output filters as well as the energy losses in them must be taken into account during the design phase. Existing design methods for these output filters are tedious in use; optimality...
