Design of Grid connected Photovoltaic Inverter with Resonant Harmonic Compensator

N. Kalaiarasi | K Charishma

Abstract: The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedure for selecting the gains and parameters of these harmonic compensator's. Some Other factors considered in the design process include frequency deviation, grid synchronization, and harmonic profile. A design of grid connected photovoltaic inverter meeting the requirements of grid interconnection using MATLAB Simulink and selected experimental results are also reported.
