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

Control of Brushless Doubly-Fed Reluctance Machines under Normal and Faulty Operating Conditions [PDF]
The brushless doubly fed reluctance machine (BDFRM) is an attractive alternative technology to traditional slip-ring doubly fed induction machine (DFIM) for slip-power recovery applications with limited variable speed ranges such as wind turbines or pump-

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 ...

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,

Evaluation of low voltage ride-through capability of synchronous generator connected to a grid [PDF]
The grid compliance of generators has been largely focused on wind power generators in literatures. With the increase in installation of distributed power systems, the dynamic performance of governor controlled prime mover driven generators might be ...

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
