Inertia Emulation Control Strategy for VSC-HVDC Transmission Systems [PDF]

open access: yesIEEE 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. Voltage source converters (VSC) used in high voltage direct current (HVDC) transmission applications are often deliberately controlled in order to de-

Inertia emulation control of VSC-HVDC transmission system [PDF]

open access: yes2011 International Conference on Advanced Power System Automation and Protection, 2011
The increasing penetration of power electronics interfaced renewable generation (e.g. offshore wind) has been leading to a reduction in conventional synchronous-machine based generation. Most converter-interfaced energy sources do not contribute to the overall power system inertia; and therefore cannot support the system during system transients and ...
