Dual-loop primary frequency regulation controller for VSC-HVDC system [PDF]
2017 IEEE Manchester PowerTech, 2017 This paper presents a frequency control mechanism for an AC system through the active and reactive power loops of a VSC-HVDC system. The proposed scheme makes use of the reactive power loop for inertia support by exploiting the voltage-power sensitivity of loads, and active power droop control has been used to provide governor-like support following ...
