On September 17, 2020, the Federal Energy Regulatory Commission (FERC) released Order 2222 which aims to enable participation of distributed energy resources (DERs) aggregations in wholesale electricity markets. EPRI initiated the FERC Order 2222 Collaborative Forum at the end of 2020 to bring stakeholder together to discuss the key challenges associated with the order, recognize any remaining gaps across the different focus areas of the order, and establish a roadmap for the pragmatic implementation of the order. Participation in this Collaborative Forum has included 900+ individual participants across 30+ utility companies. This panel session summarizes those activities, makes the case for continued and increased collaboration between stakeholders, and highlights the remaining technical challenges that must be addressed by the power and energy systems community prior to full implementation of Order 2222. Key topics include wholesale market design, operation, and DER Aggregation participation models, transmission and distribution system operation and planning with active DERs, communication and coordination across multiple entities, data exchange, cyber security, and metering and telemetry, and issues related to dual participation and double counting prevention.

In the past decade, hydropower plants have successfully balanced the variability of renewable generation, minimizing the impact on power system stability.  Advanced Pumped Storage Hydropower (A-PSH) enables the integration of high penetration of renewables.  The power electronics converter allows an instantaneous and independent control of real and reactive power at the grid interface. Thus, we can accomplish the frequency and voltage regulation simultaneously, ensuring the reliable operation of power systems.   The power converter also optimizes the turbine-generator; therefore, various control objectives are programmable at the Machine Side Converter to ensure optimal turbine operations.  This panel invites a variety of presenters representing utility, manufacturer, national laboratory, university, state, and federal agencies.  We expect that the dialogs between the presenters and the audience generate new ideas, concepts, and collaborations among various engineering and business entities to ensure a successful implementation of A-PSH in many years to come.

description: Urban green infrastructure, especially trees, are widely regarded as one of the most effective ways to reduce urban temperatures in heatwaves and alleviate the adverse impacts of extreme heat events on human health and well-being. Nevertheless, urban planners and decision-makers are still lacking methods and tools to spatially evaluate the cooling effects of urban green spaces and exploit them to assess greening strategies at the urban agglomeration scale. This article introduces a novel spatially explicit approach to simulate urban greening scenarios by increasing the tree canopy cover in the existing urban fabric and evaluating their heat mitigation potential. The latter is achieved by applying the InVEST urban cooling model to the synthetic land use/land cover maps generated for the greening scenarios. A case study in the urban agglomeration of Lausanne, Switzerland, illustrates the development of tree canopy scenarios following distinct spatial distribution strategies. The spatial pattern of the tree canopy strongly influences the human exposure to the highest temperatures, and small increases in the abundance of tree canopy cover with the appropriate spatial configuration can have major impacts on human health and well-being. The proposed approach supports urban planning and the design of nature-based solutions to enhance climate resilience.

description: The measurement of large scale patterns or anisotropies in the arrival direction of high energy cosmic rays is an important step towards the understanding of their origin. Such measurements rely on an accurate estimation of the detector relative exposure in each direction on the sky : the coverage map. To reach an accuracy on the determination of this map below the one percent level one must properly identify and correct for all the environmental effects that may induce variations in the detector exposure as a function of time. In an approach, similar to the one used in anti-sidereal time analysis, we propose a method to empirically estimate and correct for those effects under the hypothesis that seasonal and diurnal variations can be factorized. We tested this method using a model ground detector of cosmic ray air showers, whose aperture varies due to the dependence of the air shower development on the atmospheric conditions.

By applying Noether symmetry the possible functions for the potential density of the fermion field and for the coupling are determined. Cosmological solutions are found showing that the non-minimally coupled fermion field behaves as an inflaton describing an accelerated inflationary scenario, whereas the minimally coupled fermion field describes a decelerated period being identified as dark matter.

In this panel, Robust Optimization (RO) which means optimization methods under uncertainty is overviewed and discussed to find new directions with Modern Heuristics in Smart Grid. Recently, the emergence of renewable energy, demand response and EVs has brought about uncertainties to smart grid. As a result, deterministic optimization methods have the limitations to handle the uncertainties. Simple stochastic programming is popular as an optimization method with uncertain variables, but it is time-consuming because of setting up the additional conditions to the formulations. To overcome that, alternative methods are required to deal with the optimization problems. As a candidate, RO is expected to aim at evaluating the optimal solution in the worst case to minimize risks. Most of the RO formulations are based on the linear programming (LP) with continuous variables so that there are limitations to what LP can solve in nonlinear Smart Grid. This panel covers new methods that introduce Modern Heuristics for the nonlinear optimization into the RO problems to overcome drawbacks of the conventional methods.  So, it is expected that the use of Modern Heuristics allows Smart Grid decision makers to provide risk free solutions to the worst case in smart grid efficiently.

A dancing of attitudes : Burke’s rhetoric on Shakespeare
Creators: name: Rowan, Stephen Charles
Publisher: name: University of British Columbia
Year: 2010

description: Since F.S. Boas coined the term in 1896, All's Well That Ends Well, Troilus and Cressida, and Measure For Measure have been generally accepted as "problem plays," and many critics have offered biographical, thematic, and formal explanations of why these plays are so "dark." In this thesis, I accept that these plays are "problems" and I propose a rhetorical explanation for dissatisfaction with them, especially with their endings. Drawing on Kenneth Burke's philosophy of literary form and his anthropology of man as the symbol-using animal, I show that in these plays Shakespeare frustrates the expectations of an audience for a definite ending through death or marriage which would define the "terms" characterized in each play; secondly, he provides no scapegoat whose victimage would allow the audience to recognize an order clearly proposed for its acceptance; finally, he supplies no symbol of order which credibly demonstrates its power to establish a renewed society. As rhetoric, these plays show an intense "dancing of attitudes" toward symbols of order and toward conventional forms which would provide a clear sense of an ending. As such, they show what Burke calls "self-interference" on the part of the playwright — a deliberate balancing of arguments for the sake of "quizzicality" toward language as symbolic action. According to this analysis, the problem plays remain problems for an audience which seeks identification with symbols of order; they are, however, a tribute to the agile mind of a master rhetorician.
Integration of Inverter-Based Resources into the Bulk Power System

Publisher: name: IEEE
Year: 2022

Achieving carbon neutrality to reduce the threat of climate change requires substantial decarbonization of all sectors of the economy. The most cost-effective, carbon-free generation sources, solar photovoltaics and wind interconnected with transmission and sub-transmission systems, will have to contribute the lion's share of the energy supply across many hours of the day and most of the annual energy needed to serve grid demand to decarbonize the electric sector. With the dominance of intermittent solar and wind coupled with battery storage and the projected retirement of fossil fuel plants that provide significant amounts of steady, controllable energy, grid operators and power system planners will need to evolve their operations and planning studies to manage inverter-based resources (IBR) to maintain grid stability.  The panel will address how to reliably integrate IBR into the bulk power system to operate a decarbonized grid. Complementary perspectives from grid operators, research organizations, and international regulatory authorities will provide lessons learned from issues faced by the industry, on-going development of reliability guidelines, standards, minimum technical requirements, and IBR modeling, performance, and analysis.

Increasing penetrations of DERs bring new challenges for distribution system state estimation mainly because the static estimation techniques which were primarily developed for passive networks can no longer be applied to active distribution networks. The dynamics introduced by inverter-based resources/DERs are spatially uneven and vary vastly in timescales, causing it difficult to apply purely static or dynamic state estimation methods to monitor the entire network. In addition, the uncertainties in DER dynamics further complicate the state estimation task. To address these challenges, combined dynamical and static state estimation methods need to be developed which include a distribution system model consisting of differential and algebraic equations to fully capture the dynamics at different timescales. This panel seeks to elaborate the urgent needs for new estimation methods and discuss potential solutions, including new extended Kalman filter algorithms, relaxation methods to reduce DAE systems to ODE systems, or steady-state and dynamics decoupling methods.

Takada et al., Nature 422, 53 (2003)) has caused a tremendous upsurge of scientific interest due to its similarities and its differences to the copper based high-temperature superconductors. Two years after the discovery, we report the fabrication of single-phase superconducting epitaxial thin films of Na0.3CoO2 x 1.3 D2O grown by pulsed laser deposition technique. This opens additional roads for experimental research exploring the superconducting state and the phase diagram of this unconventional material.

description: We investigate the long-time properties of a dynamic, out-of-equilibrium network of individuals holding one of two opinions in a population consisting of two communities of different sizes. Here, while the agents' opinions are fixed, they have a preferred degree which leads them to endlessly create and delete links. Our evolving network is shaped by homophily/heterophily, which is a form of social interaction by which individuals tend to establish links with others having similar/dissimilar opinions. Using Monte Carlo simulations and a detailed mean-field analysis, we study in detail how the sizes of the communities and the degree of homophily/heterophily affects the network structure. In particular, we show that when the network is subject to enough heterophily, an "overwhelming transition" occurs: individuals of the smaller community are overwhelmed by links from agents of the larger group, and their mean degree greatly exceeds the preferred degree. This and related phenomena are characterized by obtaining the network's total and joint degree distributions, as well as the fraction of links across both communities and that of agents having fewer edges than the preferred degree. We use our mean-field theory to discuss the network's polarization when the group sizes and level of homophily vary.

description: The alpha-beta magneto-structural phase transition in MnAs/GaAs(111) epilayers is investigated by elastic neutron scattering. The in-plane parameter of MnAs remains almost constant with temperature from 100 K to 420 K, following the thermal evolution of the GaAs substrate. This induces a temperature dependent biaxial strain that is responsible for an alpha-beta phase coexistence and, more important, for the stabilization of the ferromagnetic alpha-phase at higher temperature than in bulk. We explain the premature appearance of the beta-phase at 275 K and the persistence of the ferromagnetic alpha-phase up to 350 K with thermodynamical arguments based on the MnAs phase diagram. It results that the biaxial strain in the hexagonal plane is the key parameter to extend the ferromagnetic phase well over room temperature.

Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: In this study, we build upon a previously proposed neuroevolution framework to evolve deep convolutional models. Specifically, the genome encoding and the crossover operator are extended to make them applicable to layered networks. We also propose a convolutional layer layout which allows kernels of different shapes and sizes to coexist within the same layer, and present an argument as to why this may be beneficial. The proposed layout enables the size and shape of individual kernels within a convolutional layer to be evolved with a corresponding new mutation operator. The proposed framework employs a hybrid optimisation strategy involving structural changes through epigenetic evolution and weight update through backpropagation in a population-based setting. Experiments on several image classification benchmarks demonstrate that the crossover operator is sufficiently robust to produce increasingly performant offspring even when the parents are trained on only a small random subset of the training dataset in each epoch, thus providing direct confirmation that learned features and behaviour can be successfully transferred from parent networks to offspring in the next generation.

Improved selection of extremely red quasars with boxy CIV lines in BOSS

description: Extremely red quasars (ERQs) are an interesting sample of quasars in the Baryon Oscillation Spectroscopic Sample (BOSS) in the redshift range of $2.0 - 3.4$ and have extreme red colours of $i-W3\ge4.6$. Core ERQs have strong CIV emission lines with rest equivalent width of $\ge100$Å. Many core ERQs also have CIV line profiles with peculiar boxy shapes which distinguish them from normal blue quasars. We show, using a combination of kernel density estimation and local outlier factor analyses on a space of the $i-W3$ colour, CIV rest equivalent width and line kurtosis, that core ERQs likely represent a separate population rather than a smooth transition between normal blue quasars and the quasars in the tail of the colour-REW distribution. We apply our analyses to find new criteria for selecting ERQs in this 3D parameter space. Our final selection produces $133$ quasars, which are \emph{three} times more likely to have a visually verified CIV broad absorption line feature than the previous core ERQ sample. We further show that our newly selected sample are extreme objects in the intersection of the WISE AGN catalogue with the MILLIQUAS quasar catalogue in the colour-colour space of ($W1-W2$, $W2-W3$). This paper validates an improved selection method for red quasars which can be applied to future datasets such as the quasar catalogue from the Dark Energy Spectroscopic Instrument (DESI).

description: Artemisia argyi is a widely distributed and inexpensive plant resource, and study on its chemical compositions and biological activities will provide an important basis for its food applications and pharmaceutical developments. In this study, fourteen known guaiane-type sesquiterpenes (1-14), four known eudesmane-type sesquiterpenes (15-18), two known germacranolide-type sesquiterpenes (19, 20), and eight other types of terpenoids (20-28) were isolated from the leaves of A. argyi by polyamide and ODS CC and HPLC. The structures of all compounds are determined by 1 D NMR (1H-NMR、13C-NMR) and literature comparison. Among them, compounds 1 and 8 were isolated from Chinese folk medicine A. argyi for the first time. Besides, the LPS-induced RAW264.7 cell model has been evaluated the anti-inflammatory activities in vitro by the Griess reagent. The results indicated that the guaianolide sesquiterpenoids obtained from A. argyi have an excellent ability to inhibit NO production, especially Argyin A, a guaianolide sesquiterpenoid with isovaleryloxy substitution.
Accuracy Assessment of Medium Voltage Smart Grid Sensor Systems - A New Approach

Publisher: name: IEEE
Year: 2022

Voltage and current sensors, also known as non-conventional or low-power instrument transformers, offer significant benefits which will prove essential in facing the growing application challenges of the evolving grid.  As this newer technology has fundamentally different operating characteristics than its predecessor technology, a well thought out approach to validating operational sensor systems is essential.  Lack of standardization of sensors and sensor system components and communications, widely varying device specifics and performance ratings, and a lack of tried-and-true compatibility all lead to many opportunities for error in the outcomes realized in using these systems.  Whether used for protection, measurement, or control applications, a greater understanding of concepts such as accuracy, uncertainty, and precision, and the variety of factors which can affect these in real world deployments, is essential. In this panel session we will discuss sensor device and system considerations, best practices for validating sensor systems and their performance for various applications, and real-world results from employing a holistic approach to system validation.  Discussion of actual sensor component and system testing outcomes realized will provide valuable insights which will be useful when planning deployments of this technology in grid applications.

The electric grid is currently undergoing major transformation due to rapid integration of high levels of renewable generation, addressing society’s decarbonization requirements and enabling electrification of transportation. At the same time, it is frequently facing major threats s due to extreme weather conditions, such as cold weather, storms, earthquakes and wildfires. We, as an industry are faced with major challenge to improve grid resiliency and make electric system more robust and intelligent. New strategies, technologies and processes need to be identified and implemented in order to support reliable delivery of the electric energy to the end consumer and ensure that the system can be restored in safe, reliable and expedient manner.  The proposed panel, organized by the IEEE PES Corporate Engagement Program (CEP) will focus on resiliency issues currently facing the electric utility industry on both Transmission and Distribution areas and discuss new developments, strategies and improvements that are being evaluated and implemented to make grid more resilient.

description: Generating high-fidelity, tunable entanglement between qubits is crucial for realizing gate-based quantum computation. In superconducting circuits, tunable interactions are often implemented using flux-tunable qubits or coupling elements, adding control complexity and noise sources. Here, we realize a tunable $ZZ$ interaction between two transmon qubits with fixed frequencies and fixed coupling, induced by driving both transmons off-resonantly. We show tunable coupling over one order of magnitude larger than the static coupling, and change the sign of the interaction, enabling cancellation of the idle coupling. Further, this interaction is amenable to large quantum processors: the drive frequency can be flexibly chosen to avoid spurious transitions, and because both transmons are driven, it is resilient to microwave crosstalk. We apply this interaction to implement a controlled phase (CZ) gate with a gate fidelity of $99.43(1)\%$ as measured by cycle benchmarking, and we find the fidelity is limited by incoherent errors.

description: Hard high-energy pion-nucleus bremsstrahlung, $π^- +A\toπ^- +γ+A$, is studied in the Coulomb region, i.e. the small-angle region where the nuclear scattering is dominated by the Coulomb interaction. Special attention is focussed on the possibility of measuring the pion polarizability in such reactions. We study the sensitivity to the structure of the underlying the pion-Compton amplitude through a model with $σ$, $ρ$, and a_1 exchanges. It is found that the effective energy in the virtual pion-Compton scattering is often so large that the threshold approximation does not apply.
