Security and privacy in smart grid advanced metering infrastructure network.
(2018)a group of consumers are sufficient for data recipients to perform their duties. Unfortunately, this approach usually relies on cryptographic algorithms which increases the overhead on computations and communication for ... -
Energy efficiency and interference management in long term evolution-advanced networks.
(2019)Cellular networks are continuously undergoing fast extraordinary evolution to overcome technological challenges. The fourth generation (4G) or Long Term Evolution-Advanced (LTE-Advanced) networks offer improvements in ... -
Microwave and millimetre radio wave propagation modelling for terrestrial line-of-sight links in Central Africa.
(2018)The rapid expansion of the global telecommunication has led to an exponential growth in the demand of wireless services. This has led to the migration to higher frequency bands in the microwave and millimeter wave spectrum. ... -
The study of the self-damping properties of overhead transmission line conductors subjected to wind-induced oscillations.
(2017)Conductors are flexible, elastic structural components of power lines. The relatively high flexibility of the conductors, coupled with the long spans and the axial tension, makes conductors to be highly prone to dynamic ... -
Power quality enhancement in secondary electric power distr[i]bution networks using dynamic voltage restorer.
(2018)This research study investigates and proposes an effective and efficient method for improving voltage profile and mitigating unbalance voltage, voltage variation disturbances in rural and urban secondary distribution ... -
Survey and assessment of the impact of embedded generation on the eThekwini electricity distribution grid.
(2016)Under frequency load shedding, rising electricity tariffs, environmental concerns, reducing costs of renewable energy technology and delays in constructing new power stations has lead consumers and producers alike to explore ... -
PMSG-based wind power integration-modelling and analysis of impacts on the dynamic performances of a power system and mitigation under stochastic wind disturbances.
(2017)Because of the ever-growing demand for electrical energy and environmental challenges of fossil fuel consumption, a priority has been given to the development of wind energy systems, among which, currently, permanent magnet ... -

Optimal energy control of a grid connected solar-wind based electric power plant.
(2016)In the present context of urge energy demand, renewable energy is considered as an alternative source of clean energy. In view of the increase in the price of fossil fuel due to its rarity and emissions, more integration ... -
DC coronation electroporation.
(2015)Cells are surrounded by a semi-permeable bilayer lipid membrane that acts as a barrier against the entry of foreign molecules. In the fields of molecular biology, biotechnology, and medicine, the ability to breach the cell ... -
Modelling physical asset risk profile using systems thinking augmented by stochastic and probabilistic inferences.
(2015)Current quantitative approaches to power asset management risk modelling have focused on financial aspects such as net present value. These approaches can neither determine nor trend the impact of technologies or renewal ... -
Analysis of the impact of a facts-based power flow controller on subsynchronous resonance.
(2012)Electric power utilities are faced with the challenge of meeting increasing demand for electric power whilst many factors prevent traditional remedies such as the expansion of transmission networks and the construction of ... -
Quantitative feedback design and construction of a two by two system with large disturbances.
(1989)The quantitative feedback theory (QFT) of Horowitz is theoretically well developed for multivariable systems but there is not sufficient knowledge on its application to practical problems. A "flying machine" consisting ... -
Modelling and analysis of turbogenerators in single machine and multi- machine subsynchronous resonance studies.
(1987)Subsynchronous Resonance (SSR) is a condition which occurs when turbogenerators are connected to series capacitively compensated transmission systems and it can cause large scale damage to the turbogenerators. The ... -
Numerical alogrithms for PWM modulators.
(1989)The development of a simple efficient Pulse Width Modulation (PWM) modulator has been a goal for many research workers. In general three techniques have been used, namely; the analogue triangular wave technique; the use ... -
A gridless, variable perveance Pierce electron gun.
(1994)This thesis covers the design and development of a modulated Pierce electron gun used in the construction of experimental travelling wave tube (TWT) amplifiers. The gun incorporated an open aperture switching electrode, ... -
Real-time interactive multiprogramming.
(1978)This thesis describes a new method of constructing a real-time interactive software system for a minicomputer to enable the interactive facilities to be extended and improved in a multitasking environment which supports ... -
Design synthesis of LCC HVDC control systems.
(2011)From the early days of HVDC system applications, the importance of mathematical modelling of the dynamics of Line Commutated Converter (LCC) HVDC systems has been appreciated. There are essentially two methodologies used ...
