摘要

This paper shows an application of a Back to Back (BtB) converter interfacing a microgrid. The idea is to take advantage of the DC link part of the BtB converter to tap power to feed a remote area through DC cables. General aspects of DC transmission in power systems are properly scaled down to use at distribution levels. Thus voltage and frequency are fixed by power converters interfacing the microgrid and the tap. By using the DC link, aspects like decoupling AC sides and independent control of active and reactive power are shown and highlighted. Although 2km does not represent a long distance for high voltage systems, it is for distribution systems, being actually not possible to do it adequately by conventional AC cables or overhead lines. The performance of the proposal has been verified in simulations. Some constraints in the system involving DC voltage, load and cable length are covered in this work, as well.
