Battery energy storage systems for primary frequency regulation in power systems
(2023-03-29)
Due to the increasing deployment of renewable energy resources, the proportion of conventional
power plants is declining. As a result, reduction of frequency-regulation capability
has become a significant challenge to ...
Methods for acceleration, and stability assessment of single-rate and multi-rate electromagnetic transient simulations
(2023-03-29)
This thesis aims to investigate methods for speeding single-rate EMT simulations of large power networks as well as develop a rigorous analytical approach for assessing the stability of multi-rate EMT simulations.
Firstly, ...
Extending the frequency bandwidth of transient stability simulation using dynamic phasors
(2023-02-14)
Transient stability is an important measure in assessing a system's overall stability. It characterizes the ability of a power system to maintain stability following major disturbances. Modern power systems whose dynamics ...
Analysis of an enclosure for a MEMS DC electric field sensor
(2023-03-20)
MEMS DC electric field sensors are successful candidates in the field of monitoring power utility infrastructure. Their delicate size and nature require them to be placed in a protective enclosure when used in an outdoor ...
Towards predicting student learning outcomes from learning management system interactions using machine learning
(2023-04-13)
Advancements in classroom technology have resulted in new types of data collection in educational settings. Along with improvements in the fields of artificial intelligence and machine learning, this educational data can ...
Toward an end-to-end design procedure for electromagnetic Huygens' metasurfaces
(2023-04-21)
This thesis presents a systematic end-to-end design procedure for electromagnetic metasurfaces. Metasurfaces are electrically thin (and often planar) transformers for electromagnetic fields. A designer aims to construct a ...
Wideband microstrip antennas using electromagnetic bandgap structures
(2020)
In this thesis, I performed a study on the electromagnetic behaviors of an Electromagnetic Bandgap (EBG) structure with a specific set of parameters, and explored the effects of the geometrical parameters ...
Enhancing performance of conventional image codecs using CNN based image sub-sampling and super resolution
(2020-10)
The goal of image compression is to reduce the number of bits required to represent
an image with a minimum loss of visual quality. However, conventional image compression algorithms, such as JPEG, produce unpleasant ...
Cooperative resource allocation schemes for multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) systems
(2020-10-08)
Currently, multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) technology has been considered as a promising multiple access technology for the fifth generation (5G) networks to improve system capacity ...
Interfacing a transient stability model to a real-time electromagnetic transient simulation using dynamic phasors
(2020-02)
This thesis presents a method to perform real-time Electromagnetic Transient (EMT) simulations for a large power system. The real-time EMT simulation can become prohibitively expensive for large power systems. A solution ...
