Abstract |
The first part of this paper intends to give an
overview of the Maximum Power Point Tracking methods
for Photovoltaic (PV) inverters presently reported in the
literature. The most well-known and popular methods, like
the Perturb and Observe (P&O), the Incremental
Conductance (INC) and the Constant Voltage (CV), are
presented. These methods, especially the P&O, have been
treated by many works, which aim to overcome their
shortcomings, either by optimizing the methods, or by
combining them. In the second part of the paper an
improvement for the P&O and INC method is proposed,
which prevents these algorithms to get confused during
rapidly changing irradiation conditions, and it considerably
increases the efficiency of the MPPT. |
