T h i s p a p e r s t u d i e s p e r f o r m a n c e s o f w i n d e n e r g y conversion system (WECS) using Permanent Magnet Synchronous Generator (PMSG). The big interest and requirements to high efficiency imposes the wind turbine to operate in variable speed mode, which inevitably requires power electronic converters to maximize the extracted power from the wind as well as decoupling generator dynamics from the grid or lo ad. The a im o f this paper is to presen t an an aly sis o f the suitable topology among the most popular rectifier systems for the generator-side converter those are: the passive diode bridge rectifier and the active six-switch two level rectifier, another rectifier system considered in this study include combinations of a diode bridge rectifier and DC-DC converter, the half controlled r e c t i f i e r t o p o l o g y i s a l s o d i s c u s s e d . T h i s w o r k p r o v i d e s a comparison study between performances of different rectifier systems to examine their performances in (WECSs) starting bymodeling of the used converters in the rectifier system, then a comparison is made between the association of (PMSG-diode rectifier) and (PMSG-diode rectifier with DC-DC buck converter), then with fully controlled rectifier, in order to discover their influences on the performances of the PMSG and the wind turbine system. Simulation results using Matlab Similink are presented to support the conclusion.

“…The power coefficient C P is a nonlinear function of β and the tip-speed ratio λ. If the swept area of the blade and the air density are constant, the value of C P is a function of λ and it's maximum at the particular λ opt [10]. For this reason, in order to fully utilize the wind energy, λ should be maintained at λ opt , which is determined from the blade design.…”

“…They consist of two back-to-back PWM converters with a common DC-link. On the other hand, control algorithm based on the Vector Control (VC) strategy has been investigated for both converters with PI control, where decoupling control of active current and reactive current is fundamental [8][9][10]. Then, the direct torque control (DTC) strategy is an alternative to VC for PMSG used in WECS.…”

This paper presents a Variable Structure Sliding Mode Control (VS-SMC) scheme and Direct Torque Control (DTC) for Wind Farm (WF) based on the Permanent Magnet Synchronous Generator (PMSG). The WF consists of a 3 PMSGs which are connected to a common dc bus system with rectifier. The dc-bus is connected to the electrical network using only one inverter system, a grid-side filter as well as the transformer. The efficiency of the WF can be greatly improved using an appropriate control approach. So, the control strategy uses the technique of DTC to regulate the speeds of PMSGs for Maximum Power Point Tracking (MPPT) mode. Besides, by employing VS-SMC the grid-side inverter is controlled to inject the generated power into the electrical network, to regulate DC-link voltage and to achieve Unity Power Factor. The used control strategies provide an optimal control solution for WF systems based on the PMSG.

“…Then, power limitation can be realized either by pitch control, stall control or active stall system. Diverse power conversion interfaces were presented in the literature for WECS based PMSG [15][16][17][18][19][20][21][22][23]. Figure 1 depicts the typical structure of WECS.…”

As the penetration of the Wind Energy Generation System (WEGS) into the modern power systems is extensively increased, an efficient control strategy of a WEGS plays an essential role in wind power utilization. This study presents Sliding Mode Control (SMC) design for the Variable Speed Wind Farm Systems (VS-WFS) based on Permanent Magnet Synchronous Generator (PMSG) and interconnected to the electric network. The proposed control laws are used to regulate both grid-side and generator converters. The generator side converters are used to track the maximum wind power. The function of the grid side inverter is to transfer the total extracted wind power from DC-link to the electric network and regulate the DC-link voltage. A SMC scheme is developed in the sense of Lyapunov stability theorem for the VS-WFS. Besides, the effectiveness of the proposed SMC scheme is demonstrated by comparison with a traditional Proportional Integral (PI) control strategy for fault conditions as well as for normal working conditions. Simulation results with Matlab/Simulink environment are presented to support the theoretical considerations demonstrating the potential contributions of both control strategies. The proposed SMC scheme can provide excellent control performance than the traditional PI strategy.
