The paper introduces a complete study of a flexible digital control device for a very large number of low voltage power systems with functions of power quality (PQ) and/or distributed generation (DG). The novel aspect of the device is its hardware and software architecture: a modular and object oriented approach allows a high ability in adaptation to different power system topologies. In this work the authors have investigated various DG systems (wind turbine, photovoltaic generators, gas powered generating set) and different functionalities of the grid interface inverter (grid connected or stand alone operation mode). The proposed control strategy allows the definition of the power flows in order to optimize the energy source exploitation.
