Paper Title
Solar Photovoltaic Power Conversion Using Modular Multilevel Converter

Single phase grid connected photovoltaic system using Modular Multilevel Converter (MMC) for power conversion is presented in this paper. Designing efficient Photovoltaic systems heavily emphasizes to track the maximum power operating point makes use of maximum power point tracking (MPPT) technique with MMC as interfacing unit into the grid is used. Perturb & Observe (P&O) technique algorithm is implemented to regulate the DC link voltage of MMC and to synchronize the grid utility voltage with the current to attain unity power factor operation. Operation of proposed MMC topology is verified by the simulation results presented in this paper. The AC output is free from the higher order harmonics and grid voltage and current are in phase. The validity of recommended system is verified by MATLAB simulation. Keywords— Modular multilevel converter (MMC), Photovoltaic (PV) array, MPPT, Grid, Total harmonic distortion(THD).
