“…Adaptive control, although old, has been of great interest and has contributed to solving many stabilization and robustness problems for HVDC transport systems [15], work has also dealt with adaptive control based on a reference model reference adaptive control (MRAC) [16]- [18] which has demonstrated the effectiveness of this type of control especially when one wishes to improve the dynamic response and take into account the parametric variations of the system. In this work, we realized an adaptive control based on the backstepping approach of this VSC-HVDC system which allows regulating the direct current (DC) voltage also the active and reactive powers under faults conditions [19]- [21].…”

The growing demand for electricity and the increasing integration of clean energies into the electrical grids requires the multiplication and reinforcement of high-voltage direct current (HVDC) projects throughout the world and demonstrates the interest in this electricity transmission technology. The transmitting system of the voltage source converter-high-voltage direct current (VSC-HVDC) consists primarily of two converter stations that are connected by a dc cable. In this paper, a nonlinear control based on the backstepping approach is proposed to improve the dynamic performance of a VSC-HVDC transmission system, these transport systems are characterized by different complexities such as parametric uncertainties, coupled state variables, neglected dynamics, presents a very interesting research topic. Our contribution through adaptive control based on the backstepping approach allows regulating the direct current (DC) bus voltage and the active and reactive powers of the converter stations. Finally, the validity of the proposed control has been verified under various operating conditions by simulation in the MATLAB/Simulink environment.

“…A gain scheduling adaptive control strategy has been tried in [4] where the effect of large disturbances has been taken into account. In [5], the advantages of automatic continuous fine tuning are combined with predetermined gain scheduling in order to achieve robustness during large disturbances. A robust coordinated control scheme for a parallel AC/DC system is proposed in [6].…”

This paper deals with design and stability of a new nonlinear fuzzy state feedback controller for HVDC systems. A novel simplified nonlinear dynamic model is developed for HVDC system that can be used to design the controller. The proposed nonlinear dynamic model decomposes into several linear systems around its important equilibrium points. These local linear models describe the plant dynamical behavior at its different operating points. The proposed controller is used in the control loops of the HVDC system. The simulation is carried out based on the Cigré benchmark model. Simulation results show improvement of overall AC/DC/AC system performance when severe faults occur, compared to the conventional controller. Also, the stable behavior of a very weak AC/DC system (SCR<2) with proposed controller is very significant when a sudden change in current order and/or a switched reduction in ESCR is applied. The same situation with conventional control brings the system into unstable region.
