“…Wind turbines should supply power (active and reactive) for voltage and frequency recovery, immediately after the occurrence of a fault [17]. The fault-ride standard stipulates that during fault occurrence, a WTG should remain steady and connected when the voltage at the point of connection drops to 15% of the nominal value for a period of 150ms [18]. In addition, when the voltage is within the shaded area, as shown in Fig.…”

“…The electrical rotor frequency of the DFIG can be varied when the power electronic converter supplies the rotor winding with the stator winding directly linked to the electric power grid, making variable-speed operation possible. The converter size is noticeably smaller than the rated capacity of the turbine generator utilised, which prevents full range operation, although the speed range is fairly adequate and losses are minimised [18]. In contrast, the generator is wholly decoupled from the electric grid in the full-scale converter configuration as shown in Fig.…”

The rising demands for a sustainable energy system have stimulated global interests in renewable energy sources. Wind is the fastest growing and promising source of renewable power generation globally. The inclusion of wind power into the electric grid can severely impact the monetary cost, stability and quality of the grid network due to the erratic nature of wind. Power electronics technology can enable optimum performance of the wind power generation system, transferring suitable and applicable energy to the electricity grid. Power electronics can be used for smooth transfer of wind energy to electricity grid but the technology for wind turbines is influenced by the type of generator employed, the energy demand and the grid requirements. This paper investigates the constraints and standards of wind energy conversion technology and the enabling power electronic technology for integration to electricity grid.

“…The power converter is usually made of two-level voltage source converters connected in a back to back configuration. The machine-side converter, also called a rotor-side converter (RSC), controls the generator torque/speed or active/reactive power, whereas the grid side converter (GSC) controls the net DC-bus voltage [3] [4] . The advantages of the DFIG are that rotor power allows variable speed, high starting torque capability, and flexible reactive power control.…”

Over the last years, there has been a strong penetration of renewable energy resources into the power supply network. Wind energy generation has played and will continue to play a very important role in this area for the coming years. Currently, the wind using a doubly-fed induction generator « DFIG» are the more used for the production of the electric energy. Our work consists of modelling of a chain of conversion of the wind energy where the doubly-fed induction generator operates at variable speed. thereafter, we consider the regulating of the active and reactive powers in order to ensure optimum operation. To this effect, we have established a vectorial control to ensure a decoupling between the electromechanical variables. The command is developed and validated using Matlab/Simulink in order to analyze by simulation the behavior of the chain in the fields of possible function.

“…Several electrical generator topologies have been analyzed in the past years [12,13]. When compared with the induction generator, doubly-fed induction generator, synchronous generator, and permanent magnet synchronous generator, the permanent magnet linear generator used in wave energy conversion seems to have a higher reliability and efficiency because the driving force of the linear motor is in a straight-line reciprocating direction [14,15]. In addition, the primary core of the permanent magnet linear generator can be sealed by epoxy resin and other materials after being embedded, which can be applied in the marine environment.…”

The emerging global wave energy industry has great potential to contribute to the world’s energy needs. However, one of the key challenges in designing a wave energy converter (WEC) is the wave energy generator. Thus, this paper focuses on the optimal design of a cylindrical permanent magnet linear generator (CPMLG), which is used for the wave energy conversion system. To reduce the end effect and enhance the magnetic field performance of the CPMLG, the level-set method is applied to the design of the topology and size for the generator. In the paper, the objective air gap magnetic field is given by the mathematical analysis method and appropriate measuring points are predetermined. The measuring points can fully reflect the distribution characteristics of the air gap magnetic field. Then, topology evolution on the permanent magnet (PM) and yoke based on the level-set method are performed. The level set function corresponding to the initial shape of the PM is constructed. The algorithm is programmed and computed iteratively using the discrete time and space variables. Finally, the performances of the CPMLG with the updated PM and width of yoke are analyzed by ANSYS Maxwell. Results show that the magnetic field distortion and the unbalance of three-phase electromotive force (EMF) of the CPMLG is reduced by the optimization of the level-set method. It has also been verified that the designed CPMLG with the level-set method could be used for WEC at different wave conditions.
