Reducing the Effect of Lightning on Step and Touch Voltages in a Grounding Grid Using a Nature-Inspired Genetic Algorithm With ATP-EMTP

IEEE Access, 2019
This paper discusses the step and touch voltages, based on body resistance, in a grounding grid after a lightning strike at a 434-/21-kV substation. To ensure grounding grid safety, the maximum step and touch voltage should not exceed the safety criteria

Grid-Impedance-Based Transient Current Control for Offshore Wind Turbines under Low-Voltage Fault

Journal of Marine Science and Engineering
In order to enhance the transient stability of offshore wind turbines (OWTs) in marine energy systems, the grid codes stipulate that OWTs should possess the low-voltage ride-through (LVRT) ability of being grid-tied and injecting reactive current during ...

Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

International Journal of Circuit Theory and Applications, Volume 54, Issue 7, Page 3545-3554, July 2026.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

Robustness and Performance Analysis of a Current‐Controlled Quasi‐Stationary Electrical Model Virtual Synchronous Machine Using a Parameter‐Dependent Operating Point

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper analyzes the robustness of a current‐controlled quasi‐stationary electrical model virtual synchronous machine. Fundamental limitations of structured singular value‐based stability analysis are revealed for nonlinear converter‐dominated power systems when parametric uncertainties significantly affect the operating point.

Consideration of Active Power in the SVC Control System for Flicker Mitigation in Wind Farms

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study integrates active power alongside reactive power inside the control system of static VAr compensator for flicker mitigation. The concurrent forecasting of active power and reactive power is done for 10 ms ahead through adaptive filter techniques, with real‐time updates of the autoregressive moving average model coefficients.
