A Control Architecture To Coordinate Distributed Generators And Active Power Filters Coexisting In A Microgrid

This paper proposes a control architecture of distributed generators (DGs) inverters and shunt active power filters (APFs) in microgrids to compensate voltage harmonics in a coordinated way. For this, a hierarchical control structure is proposed that includes two control levels. The primary (local) control consists of power controllers, selective virtual impedance loops, and proportional resonant ...
