| Simulation on the control system of photovoltaic generation is presented in the thesis. Firstly, introducing the presently application and development situation of photovoltaic technology at home and abroad. Secondly, analyzing the principle of the solar panel and building the simulation. The simulation results confirm the output of the solar cell. Thirdly, the thesis analyzes and compares with several traditional maximum power point track algorithms, puts forward improved Incremental Conductance Method. The results show that it not only meets the changeable light intensity, but also can accurately trace the maximum power point. Researching three DC-DC converters'principle, presenting that using Boost DC-DC converter to realize conversion and building the simulation model after analyze the parameters. Finally, simulating and analyzing the Inverter and all the control system of photovoltaic by MATLAB, the results show that the control method and strategy is practical. |
