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 ...

The global electrical energy consumption is rising and there is steady increase of the demand on power generation. In addition to conventional power generation units a large number of renewable energy units are being integrated into the power system. The Wind Energy Conversion system (WECS) is the most cost competitive of all the environmentally clean and safe renewable energy sources in world....

-Doubly Fed Induction Generators (DFIGs)find a great deal of application among variable speed wind turbines because of their advantages like operation at variable speed, ability to produce active and reactive power in all the four quadrants, higher efficiency, and extracting maximum electric power at different velocities of wind with the help of speed variation of the rotor and the usage of con...

Abstract—This paper presents a power control for a Doubly Fed Induction Generator (DFIG) using in Wind Energy Conversion System (WECS) connected to the grid. The proposed control strategy employs two nonlinear controllers, Backstipping (BSC) and slidingmode controller (SMC) scheme to directly calculate the required rotor control voltage so as to eliminate the instantaneous errors of active and ...

The wind energy conversion system (WECS) differs from other power systems. It is clean and pollution free. But the output of wind power plant is fluctuated in nature. It depends on the wind speed. The nature of wind is variable. The variable wind generates fluctuated power. Fluctuated output is the major problem of wind power plant. This problem can be solved by using convertor units. The secon...
