This session concerns potential often hidden benefits from using AC OPF in support of reliable, resilient and efficient decarbonization. We discuss its use for enabling system operators and planners to identify the main constraints which cause AC power flow to fail, and to suggest the most effective on-line adjustments and/or longer term system enhancements. This is needed when typically used DC tools (DC power flow, DC OPF) lead to failures to balance reactive power and/or to maintain voltages within the acceptable limits. In other words, AC OPF can be used to extend power transfers without experiencing voltage collapse. As such, it support utilization of existing thermal transmission system capacity more efficiently. Instead of simulating effects of adjustments made by system operators and/or off-line worst-case studies, an AC OPF can be used to identify the best adjustments. We further present how a computationally robust AC OPF can be used for many planning, operation and market purposes.
Presentations in this panel session:
- AC OPF-enabled decarbonization for reliable and resilient service (23PESGM3888)
- The role of AC OPF in ensuring deliverable reserves (23PESGM3890)
- Use of AC-OPF for Meeting MOD033 Regulatory Requirements (23PESGM3891)
- Implementation Aware Tool for Reliable and Resilient Power Systems (ITROOPS) (23PESGM3892)

Renormalization, running couplings and decoupling for the Yukawa model in curved spacetime

description: The decoupling of heavy fields as required by the Appelquist-Carazzone theorem plays a fundamental role in the construction of any effective field theory. However, it is not a trivial task to implement a renormalization prescription that produces the expected decoupling of massive fields, and it is even more difficult in curved spacetime. Focused on this idea, we consider the renormalization of the one-loop effective action for the Yukawa interaction with a background scalar field in curved space. We compute the beta functions within a generalized DeWitt-Schwinger subtraction procedure and discuss the decoupling in the running of the coupling constants. For the case of a quantized scalar field, all the beta function exhibit decoupling, including also the gravitational ones. For a quantized Dirac field, decoupling appears almost for all the beta functions. We obtain the anomalous result that the mass of the background scalar field does not decouple.

Presently, many utility-scale inverter-based resources (IBRs)  are in remote areas of the system where often there is sparse transmission and few synchronous generating resources. This interconnection scenario invariably leads to a low short-circuit current availability at the point of common coupling (PCC) of the IBR. Additionally, most new IBRs are connected to the grid through converter interfaces (e.g., Type 3 and 4 wind generators, photovoltaic solar generators, battery energy storage systems, etc.). Thus, the stability of an increased percentage of inverter-based IBRs in large power systems is an emerging research topic for the reliable operation of the grid. Since IBRs have controls and dynamic behavior that can be quite different from traditional synchronous machines, the mechanisms of instability in low short circuit systems need to be investigated using improved and appropriate mathematical models. This report looks at the availability, applicability, usability, and reliability of present state of the art computer simulation models for representation of IBRs. Further, limitations of the above alternative methods are discussed.

description: We report a combined experimental and theoretical study of the PdSe2-xTex system. With increasing Te fraction, structural evolutions, first from an orthorhombic phase (space group Pbca) to a monoclinic phase (space group C2/c) and then to a trigonal phase (space group P-3m1), are observed accompanied with clearly distinct electrical transport behavior. The monoclinic phase (C2/c) is a completely new polymorphic phase and is discovered within a narrow range of Te composition (0.3 \leq x \leq 0.8). This phase has a different packing sequence from all known transition metal dichalcogenides to date. Electronic calculations and detailed transport analysis of the new polymorphic PdSe1.3Te0.7 phase are presented. In the trigonal phase region, superconductivity with enhanced critical temperature is also observed within a narrow range of Te content (1.0 \leq x \leq 1.2). The rich phase diagram, new polymorphic structure as well as abnormally enhanced superconductivity could further stimulate more interest to explore new types of polymorphs and investigate their transport and electronic properties in the transition metal dichalcogenides family that are of significant interest.

description: The plasma dry reforming reaction of methane with carbon dioxide is investigated in a nanosecond repetitively pulsed discharge, a type of plasma that offers one of the highest non-equilibrium and performance characteristics. The experiment's purpose was to examine the effect of varying the sequence of high-voltage pulses for the same plasma energy. We find that when successive pulses are closer than 500 $\rm μ$s, a memory-dominated regime gradually develops, which influences subsequent breakdown events. As a result, both a higher reactant conversion and more efficient use of the energy injected into the discharge plasma are achieved.

For $n$ dimensional spaces this new flow takes into account all the components of the intrinsic curvature. For four dimensional Lorentzian manifolds it is found that the solutions of the Einstein equations associated to a "detonant" sphere of matter, as well, as a Friedman-Roberson-Walker cosmological model are examples of Riemann-Christoffel flows. Possible generalizations are mentioned.

description: We develop a comprehensive, elegant theory to explain terahertz (THz) emission from a superlattice over a wide range of applied electric field,which shows excellent agreement between theory andexperiment for a GaAs/Al{0.3}Ga{0.7As superlattice. Specifically we show that increasing electric field increases THz emission for low fields, then reduces emission for medium fields due to field-induced wave function localization, and then increases emission in the high field due to delocalization and Zener tunneling between minibands. Our theory shows that Zener tunneling resonances yield high THz emission intensities and points to superlattice design improvements.

TEG - 83 Reforming the Federal Fiscal Stabilization Program
Creators: name: Dahlby, Bev
Publisher: name: The School of Public Policy Publications
Year: 2019

description: The federal Fiscal Stabilization Program is meant to provide financial support for provinces that suffer extraordinary declines in revenues. However, the program only provided $248 million payment to Alberta in 2015-16 in the face of a $8.8 billion decline in revenues, and no support for Saskatchewan and Newfoundland and Labrador that have also suffered significant revenue reductions in recent years. We discuss the rationale for a Fiscal Stabilization Program, and three principles that should be adopted in re-designing it:


· Payments should be based on declines in a province’s own-source revenues from an average of its past years’ own-source revenues


· The program should preserve incentives for provinces to maintain prudent fiscal policies by only covering losses that exceed some percentage of “normal” own-source revenues (a deductible) and then only covering a fraction of eligible losses (co-insurance).


· Formulas determining payments should be simple and transparent with no adjustment for changes in provincial tax policies that may affect own-source revenues.


We propose some alternative formulas, consistent with these principles, for calculating the fiscal insurance payments and show the support levels that they would have provided to the provinces since the mid-1980s.

description: Recent works show that the graph structure of sentences, generated from dependency parsers, has potential for improving event detection. However, they often only leverage the edges (dependencies) between words, and discard the dependency labels (e.g., nominal-subject), treating the underlying graph edges as homogeneous. In this work, we propose a novel framework for incorporating both dependencies and their labels using a recently proposed technique called Graph Transformer Networks (GTN). We integrate GTNs to leverage dependency relations on two existing homogeneous-graph-based models, and demonstrate an improvement in the F1 score on the ACE dataset.
Protection of VSC-based HVDC Transmission Systems, Requirements, Challenges and Recent Advancements

Publisher: name: IEEE
Year: 2023

The recent technological advancements related to the power-electronic converters and DC circuit breaker have led to significant opportunities for development of Voltage-Sourced Converter (VSC)-based HVDC transmission systems and specifically HVDC grids. However, protection of the highly advantageous VSC-based HVDC transmission systems is a major challenge that is still constraining the proliferation of these emerging power systems. The impacts of DC-side faults on the VSC-based HVDC system and the host AC grid highly depend on the utilized VSC technologies (e.g.: various MMC topologies) and the system characteristics. This panel will focus on the requirements and challenges associated with protection of VSC-based HVDC transmission systems, considering the state-of-the-art converter, DC circuit breaker, and relay technologies as well as the AC and DC system grounding strategies.

description: The nuclear stellar disc (NSD) is, together with the nuclear star cluster (NSC) and the central massive black hole, one of the main components in the central parts of our Milky Way. However, until recently, only few studies of the stellar content of the NSD have been obtained due to extreme extinction and stellar crowding. With a dedicated KMOS (VLT, ESO) spectroscopic survey, we study the kinematics and global metallicities of the NSD based on the observations of K/M giant stars. We trace radial velocities and metallicities which were derived based on spectral indices (Na I and CO) along the NSD and compare those with a Galactic Bulge sample of APOGEE (DR16) and data from the NSC. We find that the metallicity distribution function and the fraction of metal-rich and metal-poor stars in the NSD are different from the corresponding distributions and ratios of the NSC and the Galactic Bulge. By tracing the velocity dispersion as a function of metallicity, we clearly see that the NSD is kinematically cool and that the velocity dispersion decreases with increasing metallicity contrary to the inner Bulge sample of APOGEE ($\rm |b| < 4^{o}$). Using molecular gas tracers ($\rm H_{2}CO$, CO(4-3)) of the Central Molecular Zone (CMZ) we find an astonishing agreement between the gas rotation and the rotation of the metal-rich population indicating that the metal-rich stars could have formed from gas in the CMZ. On the other hand, the metal-poor stars show a much slower rotation profile with signs of counter-rotation indicating a different origin of these stars. Coupling kinematics with global metallicities, our results demonstrate that the NSD is chemically and kinematically distinct with respect to the inner Bulge indicating a different formation scenario.

description: We consider a single ion confined in a trap under radiation of two traveling waves of lasers. In the strong-excitation regime and without the restriction of Lamb-Dicke limit, the Hamiltonian of the system is similar to a driving Jaynes-Cummings model without rotating wave approximation (RWA). The approach we developed enables us to present a complete eigensolutions, which makes it available to compare with the solutions under the RWA. We find that, the ground state in our non-RWA solution is energically lower than the counterpart under the RWA. If we have the ion in the ground state, it is equivalent to a spin dependent force on the trapped ion. Discussion is made for the difference between the solutions with and without the RWA, and for the relevant experimental test, as well as for the possible application in quantum information processing.

description: In a geographically distributed population, assortative clustering plays an important role in evolution by modifying local environments. To examine its effects in a linear habitat, we consider a one-dimensional grid of cells, where each cell is either empty or occupied by an organism whose replication strategy is genetically inherited to offspring. The strategy determines whether to have offspring in surrounding cells, as a function of the neighborhood configuration. If more than one offspring compete for a cell, then they can be all exterminated due to the cost of conflict depending on environmental conditions. We find that the system is more densely populated in an unfavorable environment than in a favorable one because only the latter has to pay the cost of conflict. This observation agrees reasonably well with a mean-field analysis which takes assortative clustering of strategies into consideration. Our finding suggests a possibility of intrinsic nonlinearity between environmental conditions and population density when an evolutionary process is involved.

description: We report on the layer-by-layer growth of single-crystal Al2O3 thin-films on Nb (110). Single-crystal Nb films are first prepared on A-plane sapphire, followed by the evaporation of Al in an O2 background. The first stages of Al2O3 growth are layer-by-layer with hexagonal symmetry. Electron and x-ray diffraction measurements indicate the Al2O3 initially grows clamped to the Nb lattice with a tensile strain near 10%. This strain relaxes with further deposition, and beyond about 5 nm we observe the onset of island growth. Despite the asymmetric misfit between the Al2O3 film and the Nb under-layer, the observed strain is surprisingly isotropic.

description: We consider a tight-binding model on the honeycomb lattice in a magnetic field. For special values of the hopping integrals, the dispersion relation is linear in one direction and quadratic in the other. We find that, in this case, the energy of the Landau levels varies with the field B as E_n(B) ~ [(n+γ)B]^{2/3}. This result is obtained from the low-field study of the tight-binding spectrum on the honeycomb lattice in a magnetic field (Hofstadter spectrum) as well as from a calculation in the continuum approximation at low field. The latter links the new spectrum to the one of a modified quartic oscillator. The obtained value $γ=1/2$ is found to result from the cancellation of a Berry phase.

description: We have successfully grown the single crystals of CeAg$_2$Ge$_2$, for the first time, by flux method and studied the anisotropic physical properties by measuring the electrical resistivity, magnetic susceptibility and specific heat. We found that CeAg$_2$Ge$_2$ undergoes an antiferromagnetic transition at $T_{\rm N}$ = 4.6 K. The electrical resistivity and susceptibility data reveal strong anisotropic magnetic properties. The magnetization measured at $T$ = 2 K exhibited two metamagnetic transitions at $H_{\rm m1}$ = 31 kOe and $H_{\rm m2}$ = 44.7 kOe, for $H \parallel$ [100] with a saturation magnetization of 1.6 $μ_{\rm B}$/Ce. The crystalline electric field (CEF) analysis of the inverse susceptibility data reveals that the ground state and the first excited states of CeAg$_2$Ge$_2$ are closely spaced indicating a quasi-quartet ground state. The specific heat data lend further support to the presence of closely spaced energy levels.

description: In the image fusion field, the design of deep learning-based fusion methods is far from routine. It is invariably fusion-task specific and requires a careful consideration. The most difficult part of the design is to choose an appropriate strategy to generate the fused image for a specific task in hand. Thus, devising learnable fusion strategy is a very challenging problem in the community of image fusion. To address this problem, a novel end-to-end fusion network architecture (RFN-Nest) is developed for infrared and visible image fusion. We propose a residual fusion network (RFN) which is based on a residual architecture to replace the traditional fusion approach. A novel detail-preserving loss function, and a feature enhancing loss function are proposed to train RFN. The fusion model learning is accomplished by a novel two-stage training strategy. In the first stage, we train an auto-encoder based on an innovative nest connection (Nest) concept. Next, the RFN is trained using the proposed loss functions. The experimental results on public domain data sets show that, compared with the existing methods, our end-to-end fusion network delivers a better performance than the state-of-the-art methods in both subjective and objective evaluation. The code of our fusion method is available at https://github.com/hli1221/imagefusion-rfn-nest

Concept of resiliency needs to be integrated into distribution grid planning and operation for minimizing the impact of extreme events on the grid services. Metrics are necessary to select best possible planning or operational decision among multiple options, specially with distributed energy resources (DERs). At the same time, metrics and integration into practice needs to be practical considering all the planning and operational constraints. This panel will focus on the mathematical and data-driven solutions for existing resilience practice in distribution grid operators, measuring resilience and enabling resiliency during extreme adverse events. Panel will also discuss state-of-the-art and future needs for resiliency tool for the DER-rich distribution grid.
Presentations in this panel session:
- Resilience and Reliability tradeoff in planning and operation practices (23PESGM3863)
- How FPL is building a more resilient grid (23PESGM3865)
- Measuring the Effectiveness of Utility Resilience Programs (23PESGM3866)

description: Die vorliegende Bachelorarbeit fokussiert sich auf die Transformation eines bestehenden Softwareprototyps in eine Microservices-Architektur, implementiert auf der Google Cloud Platform (GCP). Als Fallbeispiel dient die Applikation Nachrichtenmanagement, die Machine-Learning-Dienstleistungen für den Finanzsektor anbietet. Vier zentrale Forschungsfragen leiten die Arbeit: die konzeptionelle Aufteilung der Software in Microservices, die Bewältigung der Herausforderungen einer verteilten Architektur, die Umsetzung einer skalierbaren und erweiterbaren Architektur auf der GCP und die Auswirkungen der Verwendung von Serverless-Technologien. In der Arbeit wird ein systematisches Dekompositionsverfahren angewendet, unterstützt durch Domain-Driven Design, um die Software in unabhängige Microservices aufzuteilen. Die speziellen Herausforderungen und erhöhte Komplexität, die mit Microservices-Architekturen einhergehen, werden durch Ansätze wie das Saga-Pattern und Infrastructure-as-Code adressiert. Durch die Fokussierung auf Serverless-Technologien und die Auswahl geeigneter GCP-Dienste wird eine Architektur geschaffen, die minimale operationale Tätigkeiten erfordert und hoch skalierbar ist. Dabei arbeitet sie in allen Belastungsszenarien kosteneffizient - von komplett ausbleibendem Nutzerverkehr bis hin zu hunderttausenden täglichen Anfragen. Die Arbeit identifiziert zudem Herausforderungen bei der Anwendung des Saga-Patterns in Serverless-Architekturen und diskutiert alternative Ansätze für zukünftige Forschungen. Das Nachrichtenmanagement wird zum gegenwärtigen Zeitpunkt aktiv beim Partnerunternehmen weiterentwickelt. Als zukünftige Schritte stehen eine geschlossene Testphase und die darauffolgende Produktivschaltung der Applikation an.

description: A second-order Taylor series expansion of the free energy functional provides analytical expressions for the magnetic field dependence of the free energy and of the magnetization of ferrofluids, here modelled by dipolar Yukawa interaction potentials. The corresponding hard core dipolar Yukawa reference fluid is studied within the framework of the mean spherical approximation. Our findings for the magnetic and phase equilibrium properties are in quantitative agreement with previously published and new Monte Carlo simulation data.

description: Most recently, both BaBar and Belle experiments found evidences of neutral $D$ mixing. In this paper, we discuss the constraints on the strong phase difference in $D^0 \to Kπ$ decay from the measurements of the mixing parameters, $y^\prime$, $y_{CP}$ and $x$ at the $B$ factories. The sensitivity of the measurement of the mixing parameter $y$ is estimated in BES-III experiment at $ψ(3770)$ peak. We also make an estimate on the measurements of the mixing rate $R_M$. Finally, the sensitivity of the strong phase difference at BES-III are obtained by using data near the $D\bar{D}$ threshold with CP tag technique at BES-III experiment.
