Nonlinear Modeling and Transient Stability Analysis of SG–PV Infeed Systems

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
The system stability can be judged by comparing the TEF value with the critical energy at the initial state of early fault recovery, no necessary to wait until late fault recovery. This study provides a system‐level physical picture and a fast transient stability criterion for the transient stability analysis of SG‐PV infeed systems.

Enhanced Low-Voltage Ride-Through Scheme for Grid-Forming Converters Considering Current Limitation and Transient Stability Simultaneously

open access: yesSustainability
Grid-forming (GFM) converters face significant challenges in low-voltage ride-through (LVRT) due to their limited overcurrent capacity. Various transient current-limiting methods have been proposed to address this issue.

An Overcurrent Suppression Strategy for Distributed Photovoltaic Inverters Under Unbalanced Faults Based on Adaptive Linear Active Disturbance Rejection Control

open access: yesIET Smart Grid, Volume 9, Issue 1, January/December 2026.
After distributed photovoltaic (PV) systems are connected to the distribution network, the overcurrent problem caused by transient faults instantaneously threatens the safety of PV inverters and other equipment. This paper proposes a comprehensive control method that combines active‐loop adaptive linear active disturbance rejection control (A‐LADRC ...

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,

Impact of Phase Angle Jump on a Doubly Fed Induction Generator under Low-Voltage Ride-Through Based on Transfer Function Decomposition

open access: yesEnergies
During the fault period, a phase angle jump may occur at the stator or the point of common coupling, which will deteriorate the low-voltage ride-through (LVRT) characteristics of a doubly fed induction generator (DFIG). The existing LVRT studies focus on
