This paper addresses the problem of controlling wind energy conversion systems (WECS) which involve permanent magnet synchronous generator (PMSG) fed by IGBT-based buck-to-buck rectifier-inverter. The goal of the control is to maximize wind energy extraction and this necessitates letting the wind turbine rotor operate in variable-speed mode. The control strategy involves: (i) a nonlinear regula...

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...

A feasible control strategy is proposed to control a doubly fed induction generator based on the wind energy converter system (DFIG-WECS). The main aim is to enhance the steady state and dynamic performance under the condition of the parameter perturbations and external disturbances and to satisfy the stator power response of the system. Within the proposed control method, the control scheme fo...

Renewable-based sources can be interconnected through power electronic converters and connected with local loads energy storage devices to form a microgrid. Nowadays, DC microgrids are gaining more popularity due their higher efficiency reliability as compared AC microgrid systems. The Microgrid has electronics between the renewable-based sources. controlled an efficient control algorithm for m...

This paper proposes a new technique of using Axial Flux Induction Machines (AFIMs) for wind energy conversion systems. The Power Generation by wind is found to be enhanced by using a Twin Rotor Axial Flux Induction Machine (TRAFIM). By using Axial Flux Induction Machines, the gear box ratio can be reduced. The Single air gap and TRAFIM have been mathematically modeled in the environment of MATL...

In this paper, a wind energy conversion system (WECS) is presented for the electrification of rural areas with availability. A three-phase AC-DC converter based on bridgeless Cuk used power extraction from permanent magnet synchronous generator (PMSG). The topology enables elimination front-end diode bridge rectifier (DBR). Moreover, has fewer components, simple control, and high efficiency, ma...

<span lang="EN-US">Wind energy conversion system (WECS) is composed of many non-linear power electronic sub systems, which contribute significantly in harmonic emissions that a threat for the quality electrical power. Hence, better integration WECS grid and order to satisfy IEEE 519 standards, must inject with rate total harmonics distortion (THD) less than 5%. Multilevel Inverters are an...

This paper examines optimum selection of wind turbines between site and wind turbine generators. An analysis methodology is done at the planning and development stages of installation of wind power stations will enable the wind power developer or the power utilities to make a judicious and rapid choice of suitable wind energy conversion system from the available potential sites. The methodology...
