So, on possessing continual development the renewable energy is getting employed side by side with the traditional energy system. This paper lays down the working of a three-phase grid-connected solar photovoltaic system. The midway DC-DC boost converter facilitates the solar PV system to achieve the utmost point (MPP) besides raising its output voltage (VPV). Perturb and observe method (P&O) based maximum point tracking (MPPT) algorithm are executed to supply a controlled duty cycle to DC-DC boost converter for the production of maximum power from the solar PV system. Voltage-oriented control (VOC) with decoupled controller scheme is employed for the control of three-phase inverter, which takes on the conversion of stationary abc axis into synchronously rotating dq axis, and another way around. A correct synchronization between grid voltage and inverter current is acquired through a phase-locked loop (PLL) using the input’s quadrature method. The whole system and control schemes employed have been modelled in MATLAB/SIMULINK environment under several conditions of irradiance and temperature [3].
