Modeling of Buck Converter Models in MPPT using PID and FLC
Abstract: PV has become
universal for power utility applications in comparison to conventional
technologies when it comes to economic competitiveness. As the efficiency of
solar PV panel is low, it becomes mandatory to extract maximum power from the
PV panel at any given period of time. Maximum Power and efficiency in
Photovoltaics can be improved by Maximum Power Point tracking even under
distributed temperature and irradiance functions. The paper attempts to compare
two different Buck converter models based on predictive control. The two
converter models using State space differential equation and direct component
in MATLAB/SIMULINK are optimized through PID and FLC to obtain increased gain
and desired converter output. A PV system connected with Buck converter using
an intelligent controller (FLC) for extracting maximum power at different
environmental conditions is proposed and the results are compared with
conventional PID controller.
