“…If the battery is used, this converter is used to control the state of charge with a state control for optimum charging, while the ultracapacitor is used to regulate the dc-link voltage [40,71,79]. Other than these strategies it can also use the inner loop current control, the other voltage loop that been proposed in [67,72,76], the nite state machine in [64], or the dynamic evolution control in which the switching angle was calculated by [69]; these are able to control the power ows from the bidirectional converter. In [80] it has been suggested to use the state of charge for the ultracapacitor for the power ow process.…”

“…For example, energy storage elements such as the ultracapacitor, battery, ywheel etc can be used as storage devices by connecting them to the dc-link [66,44,67,68]. For renewable energy source applications, the battery and the ultracapacitor can be used as storage elements to improve the reliability and the stability of the grid connection [62,44,69,63,70,71,72].…”

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.

“…Energy management of active hybrid power supply has already been studied recently, for example by Thounthong et al [8], [9] who studied the control and regulation of some hybrid system; by Di Napoly et al [10] who worked on a hybrid system (ultracapacitors + batteries) for powered vehicles; by Ayad et al [11] who show the control of a unregulated hybrid system; by Hosseinzadeh et al [12] who studied the performance of a hybrid system consisting of a PEM fuel cell and lead acid battery or by Burke et al [6] who propose different topologies applied in electric, hybrid and fuel cell vehicles, among other authors. In this way the literature reveals that previous efforts have focused on the development, design and modeling of hybrid power subsystems, in order to verify its behaviour in function of the operating conditions and the control strategy.…”

Abstract.The renewable energies together with other technologies in low CO 2 emissions and the efficiency must be the base of the most sustainable new energetic system. Currently the logistics industry has a large number of vehicles (forklifts, horizontal order pickers, automated guided vehicles AGVs, tow vehicles, captive fleets applied to logistic...) intended to transport goods inside the plant. A problem associated with these logistic vehicles (electric or combustion type) is the charging time and balancing time in the batteries. Solution to the problem approached would be a system that requires a power charging times relatively short (similar to filling in the combustion system) and at the same time that have zero emissions (do not forget that they are operating in a closed environment). Typically, automated guided vehicles and forklifts are operated with leadacid batteries. The replacement of the traction battery with active hybrid power supply provide advantages as longer operating time, no recharging batteries, sizing of the fuel cell can be reduced and energy recovery during braking. Thus, energy management of an Active Hybrid Power System based on Li+ batteries, ultracapacitors and PEM fuel cells, is presented in this paper. Original lead-acid battery can be easily replaced by this new system implemented for industrial vehicles.
