DESIGN AND CONSTRUCTION OF THE SOLAR PHOTOVOLTAIC SIMULATION SYSTEM WITH THE IMPLEMENTATION OF MPPT AND BOOST CONVERTER USING MATLAB/SIMULINK

The recent ascendancy in the demand of photovoltaic power generation has become one of the most significant issue due to its many benefits. Solar PV array consists of solar PV modules which exhibit non-linear I-V characteristics. The maximum power point fluctuates throughout the day due to varying climatic conditions .This paper describes a method of modeling and simulation photovoltaic (PV) module that implemented in Simulink/Matlab. In this paper the utilization of boost converter for control of photovoltaic power using Perturb and Observe Maximum Power Point Tracking control mechanism is presented. The MPPT extracts maximum possible power from the photovoltaic and feed it to the load via boost converter which steps up the voltage to the required magnitude. Use of MPPT gives PV system maximum efficiency. The proposed PV system has been evaluated using SIMULINK library of MATLAB. The advantages of using Simulink library is that it models the system physically and the results obtained from it will be considering all the physical effect. In this paper the PV system gives 20.78 volt as output which in turn act as input to the boost converter and the boost converter gives 36.2 volt as output.
