Improving HVRT capability of wind farm with ultracapacitor and SVG cooperative control

Reli fadian
Aiming at the problem of wind turbine off-grid due to lack of high voltage ride through (HVRT) capability of wind power, the internal mechanism of wind turbine off-grid due to voltage increase of junction point caused by DC fault is elaborated.

Non‐linear coordinated control of LPMG‐based direct drive wave energy conversion system with supplementary energy storage system based on feedback linearization

IET Renewable Power Generation, Volume 18, Issue 15, Page 3077-3090, 16 November 2024.
This manuscript proposes a novel non‐linear coordinated control scheme for the direct drive wave energy conversion system (DDWECS) with a supplementary energy storage system (SESS) for grid integration. The control scheme aims to improve the dynamic performance under perpetual fluctuations of ocean waves and coordinate the machine‐side subsystem, the ...

Improving the performance of grid‐connected inverters during asymmetrical faults and unbalanced grid voltages

IET Generation, Transmission &Distribution, Volume 18, Issue 19, Page 3097-3107, October 2024.
Short circuit faults and unbalanced grid voltage are severe transient events that inverters need to be able to pass through without disconnecting from the grid. This article proposes a voltage support control scheme to support grid voltage during asymmetrical voltage drop by utilizing an optimization problem.

A coordination control between energy storage based DVR and wind turbine for continuous fault ride‐through

IET Renewable Power Generation, Volume 18, Issue 14, Page 2560-2574, 26 October 2024.
An innovative adaptive mode switching scheme has been introduced for DVR, primarily focused on minimizing the amplitude of injected voltage. A variable coordination coefficient that takes into account the margin of ESS regulation power and rotor inertia is introduced, which reduces ESS compensation capacity in DVR. Impedance‐based model considering the

Voltage Support Capacity Improvement for Wind Farms with Reactive Power Substitution Control

CSEE Journal of Power and Energy Systems
Generally, voltage support at the point of common coupling (PCC) of a wind farm is achieved through centralized static var generators (SVGs). Since the reactive power requirements occupy their capacity in a steady state, the reactive power support ...

Transient overvoltage suppression of LCC‐HVDC sending‐end system based on DC current control optimisation

IET Energy Systems Integration, Volume 6, Issue 2, Page 182-195, June 2024.
Abstract The receiving‐end system AC fault of the line‐commutated‐converter‐based high voltage direct current (LCC‐HVDC) will lead to commutation failure of the inverter side. During the fault and its recovery, AC transient low voltage and transient overvoltage (TOV) will occur in the sending‐end system.
