HVDC Systems in Smart Grids

Proceedings of the IEEE, 2017
The use of direct current (dc) power networks, either at high voltage or at medium voltage, is being increasingly seen in modern smart grids. This is due to the flexible control possible with dc and its ability to transmit and distribute power under circumstances where alternating current (ac) networks are either unable to, or less economic.

HVDC line protection for the proposed future HVDC systems

2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005
The paper reviews the ability of present protection systems to provide adequate protection for proposed future HVDC systems. This initial study reviews current protection systems used for DC line protection and highlights both the advantages and disadvantages of these systems including the factors that adversely influence their performance.
