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

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.
