Power Generation from Renewable energy sources like wind, solar, geothermal, biomass, and hydro is predominant now days and among the renewable energy sources, small hydro and wind energy have the ability to complement each other. For Power generation by small or micro hydro as well as wind systems, the use of squirrel-cage induction generators (SCIGs) is mostly adopted. As regards in recent ye...

In this work, a second-order sliding mode control algorithm is proposed for variable speed laboratory size DC generator wind turbine experiment system in order to track a speed profile and operate the wind turbine at maximum power extraction. The turbine torque, which varies with the wind speed, is considered as an unknown disturbance and rejected by the sliding mode strategy. The sliding mode ...

The variable and non-dispatchable output of wind farms brings great difficulty to the quantitative analysis of the economic operation for peak shaving of power system integrated with high penetration of wind power. For the random nature of wind power, the paper establishes a peak shaving capacity requirement model for wind power. Based on the peak shaving capacity requirement model for wind pow...

This paper presents automatic reactive power control of the isolated wind-diesel hybrid power systems. The synchronous generator (SG) is used for power generation from diesel and the induction generator (IG) is used for electric power generation from wind turbine. To minimize the gap between reactive power generation and demand, the variable sources of reactive power is used such as static sync...

This project deals with a grid connected wind-PV hybrid distributed generation system employing permanent magnet synchronous generator(PMSG) driven by a variable speed wind turbine and PV array connected to a load and the grid. PMSG wind turbine connected to a dc-dc converter via three phase diode rectifier and PV array along with a dc-dc converter connected to the DC link which operates under ...

Doubly Fed Induction Generators DFIG are nowadays widely used in variable speed wind power plants. The dynamic interaction between variable speed DFIG wind turbines and the power system which is subjected to disturbances, such as short circuit faults, is an important issue. The ability of the wind power plant to stay connected to the grid during disturbances is important to avoid a cascading ef...

Optimal operation of a wind power generating system is featured by the variable-speed constant-frequency mode in which maximum-power-capturing from the wind turbine and constantfrequency-interfacing with the power system are the primary concerns. A slip power recovery system with a doubly excited wound rotor induction machine is attractive in this situation. In this paper, field orientation con...

The present hydraulic variable-pitch mechanism of wind turbine uses three hydraulic cylinders to drive three crank and connecting rod mechanisms respectively; the blades are moved with the cranks. The hydraulic variable-pitch mechanism has complex structure, occupies a lot of space and its maintenance is trouble. In order to make up for the shortcomings of hydraulic cylinder variable-pitch syst...
