Abstract
The growth of distributed generation has consequences on Power Quality causing swells, particularly in no load scenarios. The proposed voltage regulator should be installed in the substation in the low voltage side and it consists of two controlled AC/DC and DC/AC converters with an intermediate DC energy storage link. The connection of these two converters to the electrical grid is performed directly through the distribution transformer and a series transformer which allows the voltage regulation on the distribution line. Additionally, the proposed system also allows the Power Factor correction, ensuring almost unity power factor in the Medium Voltage (MV). The obtained results show that the system allows the mitigation of sags and swells of 30%, as well as the MV Power Factor correction.
