“…For the wind turbine generator, it is most likely that the wind energy can be converted to electrical energy by using the Doubly Fed Induction Generator (DFIG), the synchronous generator and the permanent magnet synchronous generator that have been applied in [13,14,15]. The voltages generated from the generator are connected to the diode recti er and the dc-dc converter in order to control the maximum power generated by the wind source as has been discussed in [13,16,17,18,19,20].…”

“…Due to this, a converter is needed in order to control the output power ow to the storage element or to transmit it to the electrical grid network. In this case, the dc-dc converter can be used to control the power generated from the source and at the same time enable the maximum power point tracking [16,17,18,39,40]. For wind energy source, the output voltage from the generator contains variable magnitude current, voltage and frequency.…”

Currently, renewable energy sources are the main driver for future electricity generation. This trend is growing faster in the developed countries in order to reduce the green house e ect and also in response to the limited supply of oil, gas and coal which are currently the major sources for electric generation. For example, the main renewable energy sources are from wind energy and solar energy but these energies are only available to those countries that are exposed to these resources. In this thesis an alternative energy source is investigated where it can be generated from the moving objects or in form of kinetic energy. The idea is to convert the kinetic energy during landing aircraft into electrical energy which it can also be stored and transferred to the existing electrical network. To convert this kinetic energy to electrical energy, the linear generator (LG) and uncontrolled recti er have been used for energy conversion. The LG have been modelled in 3-phase model or in dq model and combined with the diode recti er that is used to generate the dc signal outputs. Due to the uncontrolled recti er the electrical outputs will have decaying amplitude along the landing time. This condition also happen to the LG outputs such as the force and the power output. In order to control these outputs the cascaded buck-boost converter has been used. This converter is responsible to control the output current at the recti er and also the LG output power during landing to more controllable power output. Here, the H ∞ current control strategy has been used as it o ers a very good performance for current tracking and to increase the robustness of the controller. During landing huge power is produced at the beginning and when the landing time is increased, the generated input power from LG is reduced to zero. Due to this, the energy storage that consits of ultracapacitor, bidirectional converter and boost converter are usedin order to store and to release the energy depends on the input power source and load grid power. The voltage proportional-integral (PI) control strategy has been used for both the converters. The last part is to transfer the energy from the source and at the ultracapacitor to the load by using the inverter as the processing device. The power controller and current controller are used at the inverter in order to control the power ow between the inverter and the grid. This is when the reference power is determined from the load power in order to generate the reference current by using the voltage oriented controller (VOC), while the H ∞ current controller is used to regulate the inverter current in order to inject the suitable amount of current that refer to the load power. Finally, a complete energy recovery system for landing aircraft with the grid connection have been put together to make the whole system to be as a new renewable energy source for the future electricity generation.

“…When the optimal rotational speed of the rotor for a specific wind speed is reached, the HCS algorithm will have tracked the maximum power point and then will settle at or around this point. In [14] a buck-boost converter circuit is used to achieve the maximum power control of wind turbine driven PMSG WECS. The PMSG is suitably controlled according to the generator speed and thus the power from a wind turbine settles down on the maximum power point using the proposed MPPT control method.…”

Manufacturer-specific models of wind turbines are favored for use in wind power interconnection studies. While they are detailed and accurate, their usages are limited to the terms of the non-disclosure agreement, thus stifling model sharing. The primary objective of the work proposed is to develop universal manufacturer-independent wind power plant models that can be shared, used, and improved without any restrictions by project developers, manufacturers, and engineers. Each of these models includes representations of general turbine aerodynamics, the mechanical drive-train, and the electrical characteristics of the generator and converter, as well as the control systems typically used. To determine how realistic model performance is, the performance of one of the models (doubly-fed induction generator model) has been validated using real-world wind power plant data. This work also documents selected applications of these models.
