For a grid connected Photo voltaic system Maximum Power Point Tracking algorithm which place a major role.A most suitable MPPT P&O technique is opted which is based upon the cost of implementation & no. of sensors requirement, complexity.Input to the PV module is solar insolation & temperature.From the solar panel voltage & current are extracted in order to find the power output.The simulation model is design for MPPT,PV module & Boost DC-DC,DC-AC converters.The various results simulated shows the improvement in P&O algorithm for MPP . Also the proposed simulated PV system requires less battery as the capacitor (feedback control) does reduce this requirement. In voltage source inverter (VSI) are generally output voltage is lower than the supplied voltage.Hence, the traditional solar power generators require minimum two power conversion stages for getting desired voltage & frequency to synchonize with ac loads. In order to overcome these limitations of the traditional controllers, the proposed controller VSI has been used to give regulated output voltage of the boost dc-ac inverter in a uni-stage for variable loads.In order to design a grid connected PV system first of all PV module is modelled in MATLAB/Simulink based on the equivalent circuit in order to find best MPPT technique.In this work we have taken 6- module PV array. These PV array operates at MPP:P pv=6*85W =510 W & AC grid RMS voltage : 120 V.
