This paper presents the design of small scale three-phase grid connected system for rural location . The proposed hybrid system includes a 3.5 kW PV panel with a DC-DC boost converter with controller for Maximum Power Point Tracking (MPPT), DC-AC inverter with decoupled power controller supplying the load and connected to the grid. The MPPT controller is used to harvest maximum power from the solar panel and decoupled power controller is used for tracking the real and reactive powers and also improves the system stability. MATLAB simulation of the proposed model is carried out to show the effectiveness of grid-connected photovoltaic systems.
