Abstract
This project in focusing on the research of MPPT control in Photovoltaic (PV) Grid Power Generation. The Photovoltaic (PV) Grid Power is very useful and environment-friendly power. Comparing with gas or coal, which are limited in the earth, photovoltaic power is almost unlimited. Therefore, the maximum power in photovoltaic power is became a hot research field now. The maximum power tracking technology has three main methods, which are perturb and observe method, incremental conductance method and constant voltage tracking method. Those three methods will be analyzed and the fittest one will be simulated by the MATLAB/ Simulink. The data and waveform which are got from simulation will be explained and analyzed that how the MPPT works.
