Abstract: DC transmission is important when there are problems of instability in AC systems, i.e. when energy is transported through long distance. This issue requires research centers and multinational companies' investments to solve it. One solution is the high voltage DC transmission or HVDC (high voltage direct current). Worldwide HVDC interconnections have helped to solve problems of instability and moreover to easily interconnect systems where voltage and frequency are not compatible. According to that, the aim of this paper is first to analyze the advantages and disadvantages of DC systems compared to AC systems, and then to show future trends in DC systems, as well as present the possible interaction with renewable energies and the convenience of considering the implementation of that technology in Colombia.
