Abstract:

This thesis investigates the economic viability of a grid connected PV system integrated with battery storage in a multifamily home in Sweden. In addition, a fleet of electric cars is added to the system and its economic feasibility is analyzed. The analysis is further classified based on the roof area available for PV installation, wherein system 1 considers nearly the entire roof area of 908 m2 and system 2 is assumed to have less than half the roof area of 360 m2 for PV installation. To help with the assessment, five scenarios are created; where scenario one represents a baseline Swedish co

Abstract:

This study sets out to examine the premises of differential validity, or the use of score differences and patterns as predictors. This presupposes a view of ability or intellect as multidimensional, and therefore regards multidimensional patterns or profiles of scores, in addition to or irrespective of the actual levels of single test scores or weighted composites, as having predictive or classificatory uses. The advantages of taking a multidimensional view of intellect as assessed by differential testing are contrasted with the advantages of a unitary approach to intelligent performance, whic

Abstract:

The modern grid system or the smart grid is likely to be populated with multiple distributed energy sources, e.g. wind power, PV power, Plug-in Electric Vehicle (PEV). It will also include a variety of linear and nonlinear loads. The intermittent nature of renewable energies like PV, wind turbine and increased penetration of Electric Vehicle (EV) makes the stable operation of utility grid system challenging. In order to ensure a stable operation of the utility grid system and to support smart grid functionalities such as, fault ride-through, frequency response, reactive power support, and miti

Abstract:

Battery electric vehicles (BEVs) could reduce CO2 emissions from the transport sector but their limited electric driving range diminishes their utility to users. The effect of the limited driving range can be reduced in multi-car households where users could choose between a BEV and a conventional car for long-distance travel. However, to what extent the driving patterns of different cars in a multi-car household’s suit the characteristics of a BEV needs further analysis. In this paper we analyse the probability of daily driving above a fixed threshold for conventional cars in current Swedish

However, a key problem prohibiting it from large scale commercialization is its severe capacity fading during cycling. The improvement of its electrochemical cycling stability is greatly attributed to the suppression of Jahn-Teller distortion at the surface of the Li

碩士<br>國立臺北科技大學<br>電機工程研究所<br>105<br>Recently, there is a global trend of developing green energy related product, and the application of secondary battery is among the mainstream study. Because there are different voltage requirements for electrical appliances, the battery needs to be connected in series for the required voltage. Therefore, a safe balance of batteries becomes an important topic, and that can be achieved by effective battery management system (BMS). A battery management system can be either active or passive balance. The passive-balance system occupies smaller space and is more

碩士<br>國立臺灣大學<br>電機工程學研究所<br>105<br>Lithium batteries have recently become popular energy-storage devices for many portable products. There are a variety of control schemes for the charging of such a battery. In this thesis, a specific charging configuration composed of a buck converter with a peak current-loop control and multiple outer feedback-loops control is the focus. In addition, only one feedback compensator network can be used. In the thesis, a detailed analysis of the circuit operating modes throughout a complete charging cycle is given. This analysis leads to eight different feedback

Over-charging (over-discharging) phenomenon will not occur as long as the terminal voltage of battery is strictly controlled. Therefore, LiFePO4 battery pack is suitable to apply for power sources of electric vehicles. This thesis proposes a battery charge equalization circuit with multi-winding transformer. Full-bridge converter with soft-switching is applied in primary-side o

A lead acid battery tank is used as the energy storage of the power system. The developed isolated multi-input converter is derived from the flyback dc converter for low number of active switches and isolation between each power sources. A multi-windings transformer is adopted in the converter. The renewable energy, grid and lead acid battery tank are connected to the three primary side windings respectively. The only one seco

This system consists of five major parts: a PC-based system monitoring program, a DSP control board, a power stage, the battery, and a resistive load network. The core of this battery experimental system is a DSP controlled programmable power source for programmed voltage or current waveform generation. We have developed DSP control algorithms for voltage and current regulation, in combination with a power stage developed by the laboratory, we
