Inertia Emulation Control Strategy for VSC-HVDC Transmission Systems [PDF]
IEEE Transactions on Power Systems, 2013 There is concern that the levels of inertia in power systems may decrease in the future, due to increased levels of energy being provided from renewable sources, which typically have little or no inertia.

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., 2005The 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.

Research on Power Modulation Strategy for MMC-HVDC and LCC-HVDC in Parallel HVDC System
2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019Due to the difference between MMC-HVDC and LCC-HVDC control characteristics and the mutual influence of parallel connection, its power modulation strategy is different from that of LCC-HVDC. Coordinated control strategy of parallel system of MMC-HVDC and LCC-HVDC is analyzed.
