Multichoice Control Strategy for VSC-HVdc
Multichoice control strategy -MCS-consists in the selection of the correct input signals that will allow the VSC-HVDC to enhance the transient stability of the system, increase the level of damping, provide voltage support at specific nodes or change the power flow in the system, as it is required by the system when disturbances occur or ordered by the

Transient stability analysis in multi-terminal VSC-HVDC grids [PDF]
A novel approach to transient stability analysis in multi-terminal high voltage direct current (MTDC) grids is presented in this paper. A symmetrical three-phase fault in an ac grid connected to a rectifier terminal of the MTDC grid causes the power injected into the dc grid to decrease, which in turn leads to a lower dc voltage in the MTDC grid. If dc

In this work, we investigate a lightweight HVDC converter topology that combines the strengths of line‐commutated converters (LCC) and full‐bridge modular multilevel converters (MMC) to address the high cost and large footprint of conventional HVDC stations.

Nonlinear control design for a multi-terminal VSC-HVDC system [PDF]
This paper presents a nonlinear control strategy based on dynamic feedback linearization control theory and a backstepping-like procedure for a multi-terminal voltage-source converter based high-voltage direct current (multi-terminal VSC-HVDC) system. The controller is able to provide asymptotic stability for the power transmission system with multiple

This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Research on Voltage Regulation Methods for Flexible On‐Load Tap‐Changing Transformers
The control system determines whether the output voltage magnitude of the voltage source converter (VSC) is high, low or constant and generates the corresponding pulse signals. Each pulse is generated at the valve‐triggering instant, with its width corresponding to the commutation angle.
