“…Hence, using PMSG without a gearbox could be very useful and efficient exclusively for offshore applications, where less maintenance is required. 5,6 Generally, PMSG is used in small-scale wind power generation systems, 7 and because grid codes all over the world are stepped up, directdrive PMSG-based wind-turbine systems might be preferred in future over wind-turbine systems using doubly fed induction generators (DFIG). 3,8,9 On other hand, applications of power electronics converters (PECs) in the field of power systems are making a great impact on power conditioning especially in renewable energy systems integrated into the electrical grid.…”

This paper shows a new manner to exploit the STM32F407 board in order to perform the processor in the loop (PIL) testing by reducing significantly the co-simulation time. This method requires an FT232RL USB-UART converter board as an external serial communication interface. The main advantage of this external device lies in the setting of its baud-rate using the aliasing technique. This technique provides an efficient solution to transfer data between embedded board and computer at high baud-rate. It allows speeding up the PIL testing and, therefore, makes it more flexible. The studied grid connected wind-turbine system is based on permanent magnetic synchronous generator (PMSG) followed by back-to-back bidirectional converters. The grid side converter (GSC) ensures the DC bus voltage control as well as the unity power factor, while the machine side converter (MSC) ensures the PMSG speed control. The method of the decoupled current control is presented for the GSC. The optimum tip speed ratio (OTSR) algorithm-based maximum power point tracking (MPPT) technique is developed for MSC. Both power and control parts are initially designed and simulated in the same MATLAB/Simulink

“…By adjusting the generator speed at different working points according to speed-power characteristics of wind turbines, the maximum power point is obtained. In variable speed wind turbines systems, PMSG and induction generator (IG) are commonly used [7]- [11]. PMSG is used in small turbine systems due to its high-power density, high efficiency and reliable design.…”

The main aim of this paper is to provide electric power generation using a renewable and portable method in rural and geographically problematic areas where energy transmission is not possible. Electric power generation from wind with low-cost, efficient and portable smallscale wind turbine during natural disasters (earthquake, fire, flood, etc.) leading to catastrophic consequences (long electrical blackouts) and for individual low power applications is targeted. The control of gearless Permanent Magnet Synchronous Generator (PMSG) along with load side inverter control in this project are performed using a fullrating, bi-directional, two-level, back-to-back voltage source rectifier/inverter with total of eight switches for the variable speed wind turbine. Additionally, one of the major advantages and novelty of using MRAS rotor flux linkage and stator resistance estimator in this system is to correct changes in the flux and stator resistance values in the control system. Due to its simplicity and effectiveness, the load side control is achieved by using four switch grid side inverter. To observe the total system performance, a three-phase passive load is used at the inverter output. The low-pass LCL filter is designed and used in the load side to reduce current and voltage harmonics and increase stability and efficiency of the power network. The results of the overall system are validated with the real-time DSP system. It is proved with this paper that the inclusion of a simple, effective and economical position sensorless control in the generator side show that renewable wind energy system can be a viable distributed green energy solution for rural areas.

“…Since 1996, PMSG has become more attractive than WRSG due to a decrease in the costs of permanent magnets and power converters [40]. At present, PMSG is known to be the prominent solution in directdrive, small-scale standalone WTs [22], [41]- [49]. Therefore, its possible configurations will be discussed in detail in chapter 2 (subsection 2.1.1).…”

Small-scale standalone wind turbines provide a very attractive renewable energy source for off-grid remote communities. Taking advantage of variable-speed turbine technology, which requires a partial-or full-scale power converter, and through integrating an energy storage system, smooth and fast power flow control, maximum power point tracking, and a highquality power is ensured.Due to high reliability and efficiency, permanent magnet synchronous generator seems to be the dominating generator type in gearless wind turbines, employed for off-grid applications.However, wind turbines using geared squirrel-cage induction generator (SCIG) are still widely accepted due to their robustness, simplicity, light weight and low cost. Permanent magnet induction generator, a relatively new induction-based machine, has recently been recognized in the wind energy market as an alternative for permanent magnet synchronous generator. A thorough comparative study, among these three generator types, is conducted in this research in order to enable selection of the most appropriate generator for off-grid wind energy conversion system (WECS), subject to a set of given conditions. The system based on geared SCIG has been shown to be the most appropriate scheme for a small-scale standalone WECS, supplying a remote area.Different topologies of power electronic converters, employed in WECSs, are overviewed.Among the converters considered, current source converter is identified to have a great potential for off-grid wind turbines.Three current-source inverter-based topologies, validated in the literature for on-grid WECS, are compared for off-grid WECS application. Feasibility study and performance evaluation are conducted through analysis and simulation. Among all, the topology composed of three-phase diode bridge rectifier, DC/DC buck converter, and pulse-width-modulated current-source inverter (PWM-CSI) is identified as a simple and low-cost configuration, offering satisfactory performance for a low-power off-grid WECS.A small-scale standalone wind energy conversion system featuring SCIG, CSI and a novel energy storage integration scheme is proposed and a systematic approach for the dc-link inductor design is presented. iv In developing the overall dynamic model of the proposed wind turbine system, detailed models of the system components are derived. A reduced-order generic load model, that is suitable for both balanced and unbalanced load conditions, is developed and combined with the system components in order to enable steady-state and transient simulations of the overall system. A linear small-signal model of the system is developed around three operating points to investigate stability, controllability, and observability of the system. The eigenvalue analysis of the small-signal model shows that the open-loop system is locally stable around operating points 1 and 3, but not 2. Gramian matrices of the linearized system show that the system is completely controllable at the three operating points and completely observable at...
