Optimum Distribution System Architectures For Efficient Operation Of Hybrid Ac/Dc Power Systems Involving Energy Storage And Pulsed Loads, Ahmed T. Elsayed
FIU Electronic Theses and Dissertations
After more than a century of the ultimate dominance of AC in distribution systems, DC distribution is being re-considered. However, the advantages of AC systems cannot be omitted. This is mainly due to the cheap and efficient means of generation provided by the synchronous AC machines and voltage stepping up/down allowed by the AC transformers. As an intermediate solution, hybrid AC/DC distribution systems or microgrids are proposed. This hybridization of distribution systems, incorporation of heterogeneous mix of energy sources, and introducing Pulsed Power Loads (PPL) together add more complications and challenges to the design problem of distribution systems. In this …

Optimal And Miniaturized Strongly Coupled Magnetic Resonant Systems, Hao Hu
FIU Electronic Theses and Dissertations
Wireless power transfer (WPT) technologies for communication and recharging devices have recently attracted significant research attention. Conventional WPT systems based either on far-field or near-field coupling cannot provide simultaneously high efficiency and long transfer range. The Strongly Coupled Magnetic Resonance (SCMR) method was introduced recently, and it offers the possibility of transferring power with high efficiency over longer distances. Previous SCMR research has only focused on how to improve its efficiency and range through different methods. However, the study of optimal and miniaturized designs has been limited. In addition, no multiband and broadband SCMR WPT systems have been developed and …
Hybrid Energy Storage Implementation In Dc And Ac Power System For Efficiency, Power Quality And Reliability Improvements, Mustafa Farhadi
Hybrid Energy Storage Implementation In Dc And Ac Power System For Efficiency, Power Quality And Reliability Improvements, Mustafa Farhadi
FIU Electronic Theses and Dissertations
Battery storage devices have been widely utilized for different applications. However, for high power applications, battery storage systems come with several challenges, such as the thermal issue, low power density, low life span and high cost. Compared with batteries, supercapacitors have a lower energy density but their power density is very high, and they offer higher cyclic life and efficiency even during fast charge and discharge processes. In this dissertation, new techniques for the control and energy management of the hybrid battery-supercapacitor storage system are developed to improve the performance of the system in terms of efficiency, power quality and …
