Variance‐Empirical Mode Decomposition Method for Fault Detection in MMC‐HVDC Transmission Lines
A variance‐embedded empirical mode decomposition (VEMD) method is proposed for fast and accurate fault detection in MMC‐HVDC transmission lines. By combining variance analysis with EMD, the method reliably detects various faults without communication links and remains robust to noise and non‐fault transients.

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

Application of Deep Learning in Virtual Power Plants—A Review
ABSTRACT The advancement of deep learning (DL) has substantially improved the power grid’s ability to model and optimise diverse and highly complex tasks. Although intelligent transformation is an inevitable trend, traditional approaches increasingly reveal limitations in computational efficiency, nonlinear nonconvex optimisation, and multi‐layer ...

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
