This paper proposes a novel topology for grid connected photovoltaic (PV)\nsystem based on modular multilevel converter (MMC). In this topology, a PV\narray is connected to capacitors of each submodule (SM) of the MMC through a\nDC-DC boost converter with maximum power point tracking (MPPT) control. This\ntopology will maximize the efficiency of the system in the case of partial\nshading conditions, as it can regulate the SM capacitor voltages independently\nfrom each other to realize distributed MPPT. A model predictive control is used\nto track the AC output current, balance the SMs capacitor voltages, and to\nmitigate the circulating current. The proposed PV generation topology with 7\nlevel MMC system validity has been verified by simulations via MATLAB/Simulink\ntoolbox under normal operation, partial shading and PV array failure.\n
