MPPT with Fixed voltage control method for single phase Grid connected solar PV system

A maximum power point Tracking(MPPT) technique plays a vital role to extract the maximum power from the solar PV array under variable weather conditions. This paper presents a new maximum power point tracking algorithm based Fixed voltage control method for single phase grid connected solar PV system and Double stage grid connected converters such as DC-DC Boost converter,DC-AC Inverter parameters have been Obseved.In the Inverter circuit output is connected with L,LC and LCL passive filters and grid parameters also studied, observed The main advantage of this algorithm comes from its ability to predict the approximate amplitude with the reference voltage wave forms or power that can be derived from the PV array with the help of constant voltage at variable conditions. In this Fixed voltage control method at different irradiance and temperature conditions the permissible grid parameters such as voltage,current,real,reactive power and THD's have been implemented in Simlink/MATLAB.
