In this paper, a converter control strategy able to provide ancillary services implemented for the Italian MV distribution Networks has been presented. A three stage system composed by several boost converters, a VSI Active Front End and a transformer has been considered as interface between distribution grid and DERs. The proposed control strategy operates jointly to the DMS. Simulations have been...
The effects of interharmonic distortion on static converters whose control is based on the use of PLL systems are analyzed. After some brief recalls on amplitude and phase angle modulation produced by interharmonic distortion and on basic PLL techniques, a sensitivity analysis aimed to show the performance of the presented PLL systems in presence of interharmonic voltages superimposed to the fundamental...
