Electrical power

Electricity demand is increasing, transmission line development can not keep up with it. This puts the power system in a full load state which puts the power system operating near the boundary of stability. This paper applies deep neural networks to predict power system dynamic stability.

This study aims to contribute to the development of a GaN/Ga2O3 diode that can be utilized in high-power device applications. The simulated device is calibrated against experimental GaN and Ga2O3 diodes, considering the effect of thickness of GaN layer and its doping concentration on the performance of GaN/Ga2O3 diodes. The band structures of devices are investigated to revial which factors that affect the properties of GaN/Ga2O3 diode.

The C-EPS steering system's performance is affected by a range of technical parameters, including steering column inertia, steering column stiffness, column damping, rack stiffness, rack damping, and steering column pinion radius. The simulation results in both the frequency domain and the time domain indicate the influence of structural parameters on the system characteristics.

The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

This thesis is dedicated to study how the charging behaviours of plug-in hybrid vehicles affect the local distribution network. This study focuses on two issues: the power loss and charging cost optimization. The multi-objective particle swarm optimization technique is applied to achieve the optimal charging schedule, resulting in acceptable additional power loss ratio and charging cost.

This research explores whether Environmental Management Accounting can be applied to assist an Australian cogeneration company in improving both its financial performance as well as its environmental performance. Cogeneration or 'combined heat and power', in this particular case, involves the simultaneous production of heat and electricity using a single fuel, that is, natural gas. The heat generated is then used to produce steam to meet the customers' requirements as well as boost the production of electricity.

This thesis approaches from the perspective of state management agencies in policy making to attract private investors to PPP projects in the power generation sector. There is an approach from the theoretical basis system to attract private investment in the form of PPP in the power generation sector in Vietnam. A practical approach is through surveys to assess the impact of these factors on the willingness of private investors to invest in PPP projects in Vietnam as well as assessment of the current situation.

Complex industrial systems often contain various uncertainties. Hence sophisticated fuzzy optimization (metaheuristics) techniques have become commonplace; and are currently indispensable for e ective design, maintenance and operations of such systems. Unfortunately, such state-of-the-art techniques suffer several drawbacks when applied to largescale problems.
