“…The provision of appropriate supplementary damping control of the classical HVDC system provides modulation of power flow through the HVDC link and effectively mitigates inter-area oscillations of interconnected power systems [8]. Recently, extensive research has been carried out to propose Power Oscillation Damping (POD) controllers applying classical control theory, optimal control schemes, robust control methods and the feedback linearization technique [9][10][11][12][13][14][15][16]. Classical control theory-based POD controllers are designed with a first-order approximation of the system dynamics at a certain operating condition.…”

Abstract:The existing literature predominantly concentrates on the utilization of the gradient descent algorithm for control systems' design in power systems for stability enhancement. In this paper, various flavors of the Conjugate Gradient (CG) algorithm have been employed to design the online neuro-fuzzy linearization-based adaptive control strategy for Line Commutated Converters' (LCC) High Voltage Direct Current (HVDC) links embedded in a multi-machine test power system. The conjugate gradient algorithms are evaluated based on the damping of electro-mechanical oscillatory modes using MATLAB/Simulink. The results validate that all of the conjugate gradient algorithms have outperformed the gradient descent optimization scheme and other conventional and non-conventional control schemes.

“…Although use of VSC-HVDC links for damping support has been extensively covered in the literature, it is often assumed that the converter is operating de-loaded [7], [8] (which can be economically expensive) or that some overload is available without addressing the converter physical limitations [9], [10]. In order to explicitly account for the converter overload constraints in the controller design in this work we use model predictive control (MPC) theory [11].…”

Abstract-Damping service provision through VSC-based HVDC links has been extensively covered in the literature. However, little or no attention has been paid to the available range of active and reactive power modulation when the HVDC link is already operating at rated capacity. In these conditions some overload capability is usually assumed, ignoring the physical constraints imposed by the safe operating area of the IGBT modules in the converter. This paper presents, in a unified framework, the provision of damping support from VSC-based HVDC links equipped with additional control for short-term overload capability. The performance of a Model Predictive Control (MPC) damping controller that accounts for the extended P/Q operating area of the converter is analysed. Case studies are presented to show that the extracted short-term overload capability can significantly improve the damping support from VSC-HVDC links. Simulation results also include the impact of damping control action on the junction temperatures of the IGBT modules of the converters, quantifying the effect of this service on the semiconductor temperature dynamics.

“…VSC-HVDC can respond more quickly to power unbalance than conventional synchronous generators because of the fastacting control possible with power electronics. Using VSC-HVDC controllers to support AC transmission system following frequency disturbances has been the subject of much recent research [1][2][3][4]. In spite of this there is no standard frequency support methodology at present.…”
