Multifunctional converter for power quality and power flow control in wind distributed generation systems directly connected to the grid

This paper presents a shunt-connected converter for interfacing a distributed generation system and the grid, with focus on uncontrolled small power wind generators. The objective is to show that the converter, with a suitable control strategy, is able to impose sinusoidal voltage and, in most cases, guarantee the compliance of the grid voltage with the THD standard levels. The strategy allows, simultaneously, the power flow regulation and current harmonic.
