| Summary: | Photovoltaic (PV) system has been widely used as one of the
renewable energy resources. Due to the non-linear I-V
characteristic and changes of the external environment and
load, the output power of the PV array varies according to
different situation. Hence, the maximum power point (MPP)
tracking technology is necessary to be implemented in order
to track for the only MPP on the P-V curve to increase the
energy harness from the PV array. In this study, two commonly used MPPT algorithm, perturb and observe and
incremental conductance were developed in Matlab Simulink
with a boost DC-DC converter to study the accuracy, speed
and tracking efficiency under STC, slow changing irradiance
condition and step changing irradiance condition.
Comparative studies shows that modified incremental
conductance is able to track MPP faster and more efficiently
under fast changing of irradiance. |
