This paper proposes a high-order sliding mode control (HO-SMC) with the super-twisting (ST) algorithm for maximum power point tracking (MPPT) and grid-connected wind energy conversion system (WECS), based on squirrel-cage induction generator (SCIG). The main features of this strategy are attenuation chattering phenomenon inherent in first-order its robustness against external internal disturban...

At the present time Doubly Fed Induction Generator (DFIG) based wind energy conversion systems are widely used for large wind power plants. DFIG offers many advantages for instance reduced rating power converter, low cost and reduced losses with the better efficiency, easy in realization of power factor correction schemes, variable speed operation and four quadrants active and reactive power co...

In this paper the Space Vector Control Scheme is implemented for a Wind Energy System using Three Level Impedance Source Inverter (ZSI). The wind energy system uses a Self Excited Induction generator (SEIG) which is the most emerging application in the field of Wind Energy Conversion System (WECS). The proposed system is modelled with a generator-side Diode Bridge Rectifier and a Stand-Alone si...

Wind energy is one of the most promising renewable energy resources. Due to instantaneous variations of the wind speed, an appropriate Maximum Power Point Tracking (MPPT) method is necessary for maximizing the captured energy from the wind at different speeds. The most commonly used MPPT algorithms are Tip Speed Ratio (TSR), Power Signal Feedback (PSF), Optimal Torque Control (OTC) and Hill Cli...

More than one hundred countries are using wind energy due to their easy implementation, cheap energy, and high energy efficiency. Implementation of FACTS devices in Wind Energy Conversion Systems (WECS) has been dramatically improved due to cooperative and accurate performance of FACTS devices. However, dealing with wind turbine faults promptly is crucial. Short-term and long-term faults may ha...

Ocean energy is an underutilized renewable source compared with hydropower and wind power. Therefore, the development of economical efficient wave converters (WECs) important crucial for offshore power generation. The mooring tensioner a critical device that can be used in point-absorber-type WECs, semisubmersible floats oil gas drilling, floating turbines. A system to create, reduce, or mainta...

In this article, the type of roller slip behavior that may result in formation white-etching cracks (WECs) wind turbine gearbox bearings is identified. A new hypothesis based on inner raceway normal contact load magnitude at time proposed as probable cause WECs. For purpose, maximum loads are identified when occurs high-speed shaft different mean speeds. Subsequently, annual probability occurre...

This paper aims to increase the power production of gearless permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) in strong (greater than 25 m/s) speed regions. In general, most turbines cut off when is over cut-out rate; as a result, generation farm decreases. study introduces look-up table pitch angle and rotational control generate extra region.

INTRODUCTION Accurately assessing potential far-field environmental impacts due to wave energy converter (WEC) arrays is needed for commercialization of wave energy. One of the barriers to development is how to assess environmental concerns related to the potential effects these arrays will have on the nearand farfield wave climate. In order for projects in the United States to be approved, reg...
