The utilization of the wind to generate electrical energy is increasing rapidly throughout the world. By the end of 2009, the worldwide installed wind capacity reached 159,213 MW (World Wind Energy Report 2009). Wind turbine generators can be added and are being added in large grid connected electric power systems. Wind power, however, behaves quite differently than conventional electric power ...

Electrical power production is the main target required from wind turbines. This paper describes an approach for wind turbine controller as a vital part of the turbine, where this controller is based on Artificial Neural Network technique and a control scheme has been applied and validated by detailed simulation in MATLAB 6.5/Simulink. The proposed controller enhances the reactive power affecte...

C ONDITION MONITORING, DIAGNOSIS, PROGNOSIS, AND INTELLIGENT HEALTH MANAGEMENT are effective means to reducing the downtime and maintenance cost and improving the reliability, capacity factor, and lifespan of wind energy conversion systems. These benefits will make wind energy a more cost-effective, reliable source for green electricity generation. These important issues have drawn more and mor...

This paper presents a wind energy conversion system (WECS) for grid-isolated areas. The includes squirrel-cage induction generator (SCIG) and battery-assisted quasi-Z source inverter (qZSI). batteries ensure reliable stable operation of the WECS in spite power oscillations. maximum is captured from both turbine (WT) SCIG through adjustment WT speed operating flux, respectively. utilized point t...

Wavelet transform is proposed in this paper for detection of islanding and fault disturbances distributed generation (DG) based power system. An IEEE 14-bus system with DG penetration is considered for the detection of disturbances under different operating conditions. The power system is a hybrid combination of photovoltaic, and wind energy system connected to different buses with different le...
