Modern control algorithms in the emerging power systems process information delivered mainly by distributed, synchronized measurement systems, and available in data streams with different reporting rates. Beyond existing measurement approaches currently embedded in SCADA framework, smart meters and high-resolution waveform-based monitoring devices like phasor measurement units (PMUs) which can include fault-recorder functionality, a new paradigm is on the way to be largely deployed, based on synchronized measurement information conveyed by point-on-wave and sampled-values delivered by new instrument transformers. However, it is expected that on short time horizon the two approaches will co-exist and this requires special attention to be paid to the different information compression rate offered by each measurement chain: for example, the lossless compression in case of sampled-data standard has to be correlated with the lossy information model used by the phasor measurement systems.

Mihaela Albu, Ph.D.
In addition, there are several applications where synchronized data received with high reporting rate has to be used together with aggregated data from measurement equipment having a lower reporting rate (complying with power quality data aggregation standards) and the accompanying question is how adequate the energy transfer models in such variety of cases are. For example, the emerging active distribution grids operation is impacted by high variability of the energy transfer and consequently a new model approximation for its characteristic quantities (voltages, currents) is needed. Such a model is required not only in order to be able to correctly design future measurement systems but also for better assessing the quality of existing “classical” measurements, still in use for power quality improvement, voltage control, frequency control, network parameter’ estimation etc. The state-of-art in power quality measurements and associated signal processing is applied in emerging control algorithms dedicated to microgrids (including DC and hybrid) and energy communities, new systems with low inertia and therefore unprecedent operational constraints. Some of those constraints are linked to measurement processes with operational features and therefore they might fail to meet the needs of the user, unless a careful analysis of the model uncertainties is performed. The talk will address:
o Measurement paradigm in power systems
o Phasor Measurement Units and WAMSC
o Model uncertainty and measurement sources of errors
o Information compression, lossy algorithms used in existing measurement systems
o Applications and challenges
o Data Analytics for Power Profiles
This presentation provides an overview of these techniques, with examples from worldwide measurement solutions enabling modern control deployment.

Title: Artificial Intelligence (AI) Based Fin-Tech Applications using Blockchain Security

Dr. Muhammad Manshad Satti
- CEO IT Butler, Smart Solutions & EduServ
Over the last two decades, there have been several digital technologies, which have been transforming businesses and society at large. Blockchain is one of the most promising developments in the information technology domain and offers numerous benefits for not just industry but also government in providing better governance and public service. In brief, Blockchain is a technology which enables a ledger that can be accessed by all parties involved in the transaction and can act as the universal refutable depository of all transactions between involved parties It is essentially a global public ledger capable of automatically recording and verifying a high volume of digital transactions, regardless of location.

Dr. Manshad Satti
Alhough the word Blockchain became synonymous with cryptocurrencies over the last few years, the benefits involved in Blockchain have already attracted immense traction, and subsequently investments, from the financial sector as well as many other technological giants over the world. The technology holds the ability to change the way the financial sector works and would result in favorably impacting many other industries including technology, healthcare, supply chain, public-sector applications, consumer goods, media, telecom, law enforcement, ride hailing, and many other areas.

Title: Alternative Substrate Technologies for III-Nitride LEDs

Ian Ferguson
- Prof. and Dean,
  Southern Polytechnic College of Engineering and Engineering Technology
  Kennesaw State University
  Georgia, USA
Light emitting diodes (LEDs) have proven themselves as the next-generation lighting technology. However, obtaining high-performance green and longer wavelength LEDs, requiring InGaN alloys with higher indium content has still proved difficult. One major problem is that the lattice mismatch between InGaN active quantum wells and the surrounding GaN layers worsens with increasing indium content. In addition, the localization mechanism associated with compositional fluctuations that allow bright LEDs in the blue is no longer valid. In this work, ZnO substrates are used for GaN and InGaN growth by metalorganic chemical vapor deposition (MOCVD). ZnO offers many advantages for GaN and InGaN due to its closely matched lattice constant, similar thermal expansion coefficients, and its ability to also be easily chemically etched, which results in improved light extraction.

Ian Ferguson, Ph.D.
However, H2 etching of the ZnO substrate at high temperatures, Zn diffusion out of the substrate, and the stability of an oxide substrate in a highly reducing atmosphere still cause many issues during MOCVD growth. The direct nucleation of GaInN on ZnO is considered in this work and the use of some native and non-native III-Nitride transition layers. The transition layer was grown on the substrates before or during the MOCVD growth to prevent Zn diffusion, protect the ZnO substrate from H2 back etching, and promote high-quality nitride growth on the ZnO substrates. It was found that Al2O3 grown by Atomic Layer Deposition (ALD) on ZnO was a particularly effective transition layer. High-resolution x-ray diffraction (HRXRD) measurements revealed that the thin Al2O3 layers after optimal annealing showed distinct wurtzite GaN and InGaN films grown epitaxially on ZnO with a mirror-like surface, no etched pits, and no peeling off. This work was extended to LEDs grown on Si with an ALD Al2O3 transition layer and these devices had a turn on voltage of less than 5V.

Title: Advanced Materials for Sustainable Energy Applications

Any material's optical, thermal, mechanical, electrical, and magnetic characteristics are all affected by its grain size especially at nanoscale and this is vital for applications of such advanced materials in the field of energy harvesting, energy storage, and production of green hydrogen from water. Our group has recently developed a green, cost-effective technique called pulsed laser ablation in liquids, or PLAL, for the creation of innovative functional nanocomposite materials. The nanoparticle size and structural alteration during laser irradiation are the distinctive features of our PLAL technique. In PLAL, the aqueous medium containing the targeted materials was exposed to a pulsed laser beam (with a certain wavelength, pulse repletion rate, pulse duration, and pulse energy) for a predetermined amount of time.

M. Ashraf Gondal, Ph.D.
The three primary processes—photo-induced particle fragmentation, photo-induced chemical reactions, and photo-induced defect engineering—all entail intricate chemical kinetics and physical mechanisms and are crucial to the PLAL-based synthesis. We have successfully synthesized the improved and desired material characteristics needed for the development of energy-harvesting devices such as thermoelectric devices, third-generation dye-sensitized and perovskite solar cells, and energy storage devices like light-sensitive supercapacitors, nano catalysts for electrocatalysis of water for green hydrogen production and photodetectors. Some recent results achieved at our laboratory regarding these developments will be discussed.
