“…For instance, Venkataraman et al [51] use H ∞ optimal control with the aim of increasing the damping of the power systems using uncertainty representations to cover the dynamic changes associated with different operating points. In [52], exact linearisation is used with similar objectives. Hazra et al [53] analyse the selection of several measures and control signals in order to achieve the maximum effect on the transient response of the AC grids.…”

More interconnections among countries and synchronous areas are foreseen in order to fulfil the EU 2050 Target on the renewable generation share. One proposal to accomplish this challenging objective is the development of the socalled European SuperGrid. Multi-terminal HVDC networks are emerging as the most promising technologies to develop such a concept. Moreover, multiterminal HVDC grids are based on highly controllable devices, which may allow not only transmitting power, but also supporting the AC grids to ensure a secure and stable operation. This article aims to present an overview of different control schemes for multi-terminal HVDC grids, including the control of the power converters and the controls for power sharing and the provision of ancillary services. The article also analyses the proposed modifications of the existing control schemes to manage high participation shares of wind power generation in multi-terminal grids.

“…The problem investigated in this paper is inspired by the work of Eriksson et al [5], on utilization of HVDC links to enhance system stability and dampen system oscillations. A major difference is that here the backstepping method will be applied in designing the nonlinear controller, instead of input-output exact linearization.…”

Abstract-This article regards a power system containing multiple High Voltage Direct Current (HVDC) links. The topic is to exploit the HVDC lines' ability to control the power supplied by them to increase the stability of the system. The nonlinear controller-design method backstepping is applied to design a controller for the direct current (DC) through each HVDC link.The simulation results show that the controller increases both transient stability and damping when some non-permanent errors are imposed on the system.

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.
