Abstract(s)
The number of grid-connected inverters is
growing due to the expansion of the use of renewable energies
(RE) systems and this may affect grid power quality and
stability. Some control algorithms reduce injected current
harmonics and add new possibilities to the converter. This paper
implements and analyses the proportional integral (PI)
controller in the synchronous frame and the proportional
resonant (PR) controller with and without the harmonics
compensators (HC). All these control strategies have proven to
be effective and robust. However, the PR+HC controller
presents better output current quality. The PI and PR
controllers have similar performances. This work also compares
the harmonic content of the current with the IEEE 1547
reference and with three commercial inverters from different
manufacturers.
