Experimental Verification of the Performance of a Nonlinear Regulator Based on Genetic Algorithms in Improving the Power Quality of DFIG

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This experimental work investigates the energy control of the doubly fed induction generator. The energy control is performed using a direct power control based on a fractional‐order proportional‐integral (FOPI) regulator. The PI regulator parameters are calculated using a genetic algorithm. The use of this strategy ensures stable operation of the DFIG,

Enhancement of Passive Sliding Mode Control Model for LVRT Capability in DFIG Based Wind Turbines

open access: yesWind Energy, Volume 28, Issue 6, June 2025.
ABSTRACT Doubly fed induction generator (DFIG) is vulnerable to transient stability situations occurring on the grid side. First of all, with the models to be developed in the wind turbines, LVRT capability must be provided depending on the grid code requirement for various problems that may occur, such as overcurrent, voltage, and uncertainty in ...
