Abstract: Nowadays, renewable energy sources (RES), especially photovoltaic (PV) systems, are popularly used as distributed generators. This is due to availability of high-power grid-tied inverters (GTIs) used for interconnecting PV systems with grid. The PV based distributed generation (DG), conventionally used for exchange of active power with grid, further can be controlled for added functionalities of reactive power exchange, voltage compensation, and harmonic mitigation. This multi-functional operation is achieved by effectively controlling the grid-tied inverter of DG. Such multi-functional control of grid-tied inverter is analysed in this paper. For control of multi-functional grid-tied inverter (MFGTI), comprehensive power quality evaluation (CPQE) index technique is used. In this paper, effective control of the space vector modulation (SVM)-based hysteresis controlled CPQE-based GTI is presented through simulation studies. Effective performance of the proposed GTI for active power exchange as well as voltage compensation during fault condition is presented.
