This paper presents an adaptive nonlinear controller for Doubly-Fed Induction Generator (DFIG) in wind power generation. The control objective is to extract the maximum power (Maximum Power Point Tracking) and have a specified reactive power at the generator terminal despite the variable wind speed and the unknown mechanical parameters and mechanical torque. To achieve such a decoupled control,...

This paper proposes a novel optimal current given (OCG) maximum power point tracking (MPPT) control strategy based on the theory of power feedback and hill climb searching (HCS) for a permanent magnet direct drive wind energy conversion system (WECS). The presented strategy not only has the advantages of not needing the wind speed and wind turbine characteristics of the traditional HCS method, ...

This paper proposes an optimized model and control strategy for variable speed wind turbine using permanent magnet synchronous generator (PMSG). Models and equations that describe different components of the wind energy conversion system (WECS) are addressed and their implementations into PSCAD/EMTDC are described. There are different types of synchronous generators, but the PMSG is chosen. It ...

WECS Permanent Magnet Synchronous Generator (PMSG) driven by wind turbine. variable frequency voltage output of PMSG is rectified Diode Bridge Rectifier (DBR) stepped up Super Lift Luo Converter (SLLC 1), finally, ...

Wind energy conversion systems (WECSs) are considered green generators, environmentally friendly, and fully suitable sources to replace fossil sources. WECS’s output power is hugely dependent on the random nature of wind. There many solutions improve for WECSs, such as adjusting profile turbine blades, locating installation places, improving etc. Nevertheless, maximum point tracking (MPPT) algo...

Wind Energy Conversion System (WECS) based on Doubly Fed Induction Generator (DFIG) connected to the grid is subjected to high transient currents at rotor side and rise in DC-link voltage during voltage sag at stator/grid side. To secure power system operation wind turbines have to meet grid requirements through the Low voltage ride through (LVRT) capability and contribute to grid voltage contr...
