IEEE transactions on industry applications, 2023
With the increasing penetration of renewable energy, power system inertia is reduced; thus, frequency stability faces tremendous challenges. Offshore wind farms (WFs) are often integrated to the grid through a voltage-source-converter-based high-voltage ...

IEEE Transactions on Power Systems, 2022
The existing research on voltage-source converter HVDC (VSC-HVDC) system stability mostly focuses on small-signal stability analysis methods. However, when large-signal disturbances occur, the intrinsic nonlinearity of the VSC-HVDC system becomes ...

International Journal of Electrical Power & Energy Systems, 2022
This paper presents three intelligent approaches for fault detection, classification and location in a three-terminal VSC-HVDC system. The proposed approaches are all based on ANNs, although each one has a specific pre-processing step to process the DC ...

Variable-Inertia Emulation Control Scheme for VSC-HVDC Transmission Systems
IEEE Transactions on Power Systems, 2021This paper proposes a novel variable-inertia emulation control (VIEC) scheme that enables voltage-source-converter based high-voltage DC (VSC-HVDC) transmission systems to flexibly support AC grid frequency stability like synchronous generators. The VIEC

VSC-HVDC Station With SSSC Characteristics
IEEE Transactions on Power Electronics, 2004Commercial installations of voltage-source converter-high voltage direct current (VSC-HVDC) are now in service as asynchronous link and as underwater/underground DC transmission. The research reported in his paper is directed to providing VSC-HVDC with synchronizing power and damping power so that after a transient the steady-state is reached in ...

In the case of VSC-based HVDC transmission systems, the transfer of power is controlled in the same way as in the case of a classic HVDC transmission. The inverter side controls the active power, while the rectifier side controls the DC voltage [33, 56]. With classic HVDC, the reactive power cannot be controlled independently of the active power.

Towards interoperability in VSC-HVDC Networks
2022High voltage direct current (HVDC) transmission infrastructure plays a key role in enabling the integration of renewable energy sources (RES). Moreover, the grid of the future is expected to have a high penetration of power electronics interfaced devices (PEIDs), which play a fundamental part in the energy transition towards carbon neutrality.
