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

Optimal control design for VSC-HVDC systems [PDF]
2013 International Conference on Electrical Engineering and Software Applications, 2013 This paper deals with modeling and optimal control design of VSC-HVDC transmission system in order to enhance system stability. The steady of the state mathematical model for GL (Generator-Load) VSC-HVDC system is developed and the decoupled relationship between the controlling variables is proposed.

Nonlinear control design for a multi-terminal VSC-HVDC system [PDF]
2013 European Control Conference (ECC), 2013 This paper presents a nonlinear control strategy based on dynamic feedback linearization control theory and a backstepping-like procedure for a multi-terminal voltage-source converter based high-voltage direct current (multi-terminal VSC-HVDC) system. The controller is able to provide asymptotic stability for the power transmission system with multiple

A Novel Method for Starting of VSC-HVDC System
International Journal of Recent Technology and Engineering (IJRTE), 2021 The voltage source converters (VSCs) are the circuits, which convert the power from one form to the other. The application of voltage source converter is vital in HVDC systems. The voltage source converter technology is employed for the smooth operation of any HVDC system.
