An overview about VSCF and LVRT in wind power generation

2017 29th Chinese Control And Decision Conference (CCDC), 2017
In recent years, wind power has been developing rapidly. As the wind power penetration from large scale wind turbines has been increasing rapidly in the transmission system, there is a higher requirement for the frequency stability and power generation efficiency of the wind power generation system, and the power grid puts forward higher continuous ...

Control Strategies for Augmenting LVRT Capability of DFIGs in Interconnected Power Systems

IEEE Transactions on Industrial Electronics, 2013
This paper presents a new control scheme for the enhancement of the low-voltage ride-through (LVRT) capability of doubly-fed induction generators (DFIGs). The LVRT capability is provided by extending the range of operation of the controlled system to include typical post-fault conditions.

Study on LVRT Decoupling Dual Synchronous Current Controller

Applied Mechanics and Materials, 2014
Under three-phase grid asymmetric fault conditions, use traditional PI controller of PV inverters to inject symmetric current positive sequence into the grid, ignoring the impact of the negative sequence current on LVRT, thus traditional PI controller does not apply to three-phase grid asymmetric faults.

Wind turbine with flywheel for improved power smoothening and LVRT

2013 IEEE Power & Energy Society General Meeting, 2013
In a scenario where renewable energy will be playing a very important role in the way the power system behaves, especially wind energy, the requirement is to make the wind energy conversion systems as flexible and controllable as other conventional generation.

Evaluation of LVRT Control Strategies for Offshore Wind Farms

2020
The penetration of offshore wind farms (OWF) connected to the electric utility grid through voltage source converter-based high-voltage DC (VSC-HVDC) increased year by year in some countries. However, penetration of HVDC-connected OWF affects electric power system voltage and frequency stability during a grid disturbance, which enforces system ...

Coordinating control method to improve LVRT ability of PMSG

2018 13th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2018
The paper firstly models the Permanent Magnet Synchronous Generation System (PMSG) and analyzes the low voltage problem. Based on the traditional vector control strategy, the paper performs combining grid-side reactive power compensation control strategy, the DC voltage reference value correcting controller and the pitch angle control strategy. Finally,

DFIG's virtual resistance demagnetization for crowbar less LVRT

2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS), 2017
Due to the increased renewable power penetration level renewable power plants have to provide low-voltage ride-through (LVRT) capability with simultaneous dynamic voltage support, to ensure the grid stability during grid faults. Concerning doubly fed induction generator (DFIG) based wind energy conversion systems (WECS) large transient electromotive ...

LVRT performance verification of PCS for wind power generation

2013 IEEE ECCE Asia Downunder, 2013
A large capacity PCS (Power Conditioning System) applied to PMSG (permanent magnet synchronous generator) of wind turbine has been developed and the operation characteristics of the PCS were tested with the same conditions in actual field operation.

Wind turbine modeling, LVRT field test and certification

2011 IEEE Power and Energy Society General Meeting, 2011
The need to validate wind turbine models for the use in grid integration studies is addressed in an increasing number of grid codes. In several countries (Spain, Australia, UK, Germany) requirements for simulation models are now required for the grid access of wind turbines.
