PV system is widely adapted to the forefront in electrical power applications such as grid connected and stand-alone systems in recent years for efficient operation of photovoltaic system. It is necessary to use a maximum power point tracking (MPPT) system to extract maximum power from a PV panel, irrespective of the temperature, irradiation conditions and electrical characteristics of the load. This project has presented the mathematical modeling of photovoltaic module and development of power converter using MATLAB/SIMULINK to simulate the basic operation of MPPT based DC-DC converter. The algorithm chosen for simulation was incremental conductance algorithm among the various MPPT algorithms studied. The algorithm would ensure maximum power point tracking by controlling the mosfet of buck-boost converter by varying its duty ratio. The TMDSSOLAR (P/C) EXPKIT is programmed as per the requirement based on different working conditions and by using graphical user interface in the software tool overall operations and performance are monitored and tabulated. To compare the various characteristics obtained from simulation model study, a solar cell & solar RELAB hardware model which is a scaled down model of solar system, is used. Solar RELAB hardware model is controlled using LABVIEW graphical user interface. This validate that the work done on solar RELAB and TMDSSOLAR(P/C)EXPKIT can be scaled to a higher rating solar system which further is an answer to a sustainable energy.
