Investigation on Fault-ride Through Methods for VSC-HVDC Connected Offshore Wind Farms
Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF). In such a situation, high voltage direct current (HVDC) transmission is a favorable opt...
متن کاملImpact of DFIG Based Offshore Wind Farms Connected Through VSC-HVDC Link on Power System Stability
With the increased levels of offshore wind power penetration into power systems, the impact of offshore wind power on stability of power systems require more investigation. In this paper, the effects of a large scale doubly fed induction generator (DFIG) based offshore wind farm (OWF) on power system stability are examined. The OWF is connected to the main onshore grid through a voltage source ...
متن کاملInput-Output Linearization and Predictive Current Controller for Offshore Wind Farm VSC-HVDC
In this paper, a nonlinear controller for VSC-HVDC transmission system is proposed. The feedback linearization based nonlinear differential-geometric techniques is used to cancel nonlinearities and decouple the input control variables. A predictive current control (PCC) method is also proposed. It can predict the current reference for the next sampling instant rapidly and accurately. Comprehens...
متن کاملA novel control method for a VSC-HVDC system in a grid-connected wind farm
The voltage source converter-high voltage direct current (VSC-HVDC) transmission is the ideal integration technology for grid-connected wind farms. A passivity-based control (PBC) method for VSC-HVDC when the wind farm voltage is unbalanced is proposed in this paper. The mathematical model of a VSC with unbalanced voltage is established. The PBC theory including dissipation inequality and syste...
متن کاملGeneric Models of Wind Turbine Generators for Advanced Applications in a VSC-based Offshore HVDC Network
This paper focuses on generic Type 4 wind turbine generators models, their applicability in modern HVDC connections and their capability to provide advanced ancillary services therefrom. A point-to-point HVDC offshore connection is considered. Issues concerning coordinated HVDC and wind farm control as well as the need of a communication link are discussed. Two possible control configurations a...
