Inertia emulation control strategy for VSC-HVDC transmission systems [PDF]
, 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.

A Survey on HVDC Power Transmission Systems
Bilecik Şeyh Edebali Üniversitesi Fen Bilimleri Dergisi, 2020 Electric power is generated and transported globally by the means of an “Alternating Current” (AC) process. However, there are some applications in which “Direct Current” (DC) power transmission is superior to AC. Problems due to the lack of technology that provides good control and regulation for conversions of DC-to-AC and AC-to-DC hampered ...
