| Abstract |
A new maximum power point tracking algorithm for single-stage converters connecting
photovoltaic panels to a single-phase grid is presented. The algorithm is based on the analysis of the
current and voltage low-frequency oscillations introduced in the PV panels by the single-phase utility
grid. The proposed control technique allows the generation of sinusoidal grid currents with unity
power factor. The proposed algorithm has been developed to allow an array of PV modules to be connected
to the grid by using a single-stage converter. This simple structure yields higher efficiency and
reliability when compared with standard solutions based on a two-stage converters configuration.
The proposed maximum power point tracking algorithm has been numerically simulated and experimentally
implemented by means of a converter prototype connected to a single-phase grid. Numerical
and experimental results are presented in the paper, showing the effectiveness of the proposed system. |
