Photo-voltaic based power generation distribution system uses power electronics converters for grid connected interfacing. In this study, a multifunctional (MFIs) grid-tie inverter with harmonics current mitigation/compensation techniques have been proposed as well as examined for the Grid tied (On-grid) Photovoltaics networks. This concept is subjected to modification and improvement of this proposed PV inverter-based control techniques with also modifications in active power filtering control algorithm. Grid -tie Photo-Voltaic inverter have same analysis and control techniques like active power filtering schemes. This study presents, conventional PLL algorithms are implemented to calculate the angular positions of the synchronous references in the system. Generated power from photovoltaic system is accounted and supplied to the control-loop. The evaluated current at the load side are progressed to achieve harmonic currents component. Then, the resultant signals are utilized to drives the grid-tied multifunctional inverter.
