Role of western HVDC link in stability of future Great Britain (GB) transmission system

Supplementary control of active power through the HVDC converter station to improve the damping of power oscillations in the GB network is demonstrated. Measurement-based system identification approach is applied to accurately estimate linear state-space models of the GB system. The linearized models are used to design controllers to improve the dynamic stability of the system using both local and remote feedback signals. The impact of possible latency in communicating the remote feedback signals is also investigated.
