Solar energy is considered as fastest growing renewable energy source after wind energy for electricity generation. And it is considered environmentally friendly. to effectively implements intelligent systems that feed household generated surplus power to distribution feeder network, modeling and simulation of the grid tied solar system is of high importance. The paper models the 1KW roof solar grid mooring system for the home connected to a 230-240 V single phase grid. The study proposes a converter topology with an efficient output voltage control system that synchronizes the phase, the frequency and voltage of the inverter with the network. The MPPT DC-DC converter, controlled by Perturb and Observe (P&O), generates the maximum power when it is detected that the mains voltage provides a control signal for the synchronous operation of the converter and the drive with the mains voltage. The developed model has been implemented and simulated using MATLAB/SIMULINK. Dynamic changes in the network voltage have been applied to evaluate the performance of the voltage controller and the DC-DC converter. The results show that the power output to the network depends not only on the level of power quality, but also on a rapid dynamic response to changes in voltage, phase and frequency, and the output of this system is low, simple, profitable and efficient. For photovoltaic solar applications.
