Research on stability issues of a grid-connected PV inverter in power hardware in the loop (PHIL) architecture
(2020-09-10)
This thesis presents an in-detail stability analysis of a Power Hardware in the Loop (PHIL) network formed through an Ideal Transformer Method (ITM) interface. The ever-growing demand for PHIL testing necessitates thorough ...
Floating gate MOS based olfactory sensor system
(2021-01)
An artificial olfactory system, capable of detecting and discriminating different volatile organic compounds, has a vast potential to solve several sensing challenges. This work demonstrates an electronic olfaction system ...
Metasurface design using electromagnetic inversion
(2020-12)
This thesis presents the theory and development of a framework for the design of electromagnetic metasurfaces. These metasurfaces can be used to systematically transform an incident electromagnetic field into a different ...
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 ...
Vascular plaque detection from optical coherence tomography images
(2021-03)
It is difficult to detect atherosclerotic plaque from optical coherence tomography (OCT) images via visual inspection. In this work, we developed three algorithms to allow us to detect atherosclerotic plaque more effectively: ...
A network synthesis based approach for frequency dependent network equivalents
(2021-02-19)
Transient simulation of large electric power systems is resource-intensive and it is often prohibitive to model the entire network in the simulator. To save computational resources, only a part of the network is modelled ...
Novel grid-forming control for black start restoration using MMC-HVdc systems
(2021-03-03)
System-wide power outages are fortunately very rare. However, when they do occur, they can catastrophically affect tens or even hundreds of millions of customers. To minimize this impact, a “black start” power restoration, ...
Probabilistic evaluation of distribution network reliability in the presence of renewable energy sources, energy storage and electric vehicles
(2021-03)
Increased penetration of electric vehicles (EVs) and renewable energy sources (RESs) in power systems can directly affect the system reliability and impose additional complexities to planning and operation due to their ...
Dynamic system equivalents using integrated PSS/E and Python for transient stability studies
(2021-03)
Transient stability studies are required to be carried out for an efficient and secure operation of power systems. However, due to the limitations of computer memory and processing speed, handling a complete set of DAEs ...
Spectral unmixing and anomaly detection for hyperspectral images
(2020-08-27)
Least Angle Regression (LARS) solves the basis pursuit optimization problem, as a sparse signal recovery algorithm, for all relevant regularization parameter values simultaneously. However, despite this efficiency of LARS, ...
