Microgrid & renewable integration at burbank water & powerSchneider Electric
This presentation reviews Schneider Electric's collaboration avec Burbank Water and Power, a cutting-edge utility company in Burbank, California, to achieve challenging renewable energy requirements and provide reliable, safe, and affordable power to its customers using advanced technology solutions.
To prepare for increased renewable energy requirements, Burbank Water and Power sought a system to manage load, distributed energy resources, distributed storage systems, generation, and variable renewables in order to balance supply and demand and avoid undesirable voltage, power flow, and power quality problems. Burbank’s Integrated Automated Dispatch System (ADS) includes Schneider Electric’s advanced Power Control System (PCS) - for automatic generator control, load forecasting, and renewable forecasting - integrated with Schneider Electric’s OASyS SCADA and WeatherSentry system. The Integrated ADS will allow Burbank to co-optimize scheduling and dispatch of conventional supply resources, distributed generation, and demand-side resources, enable better control of inadvertent interchanges, and reduce reliance on external generation. Through the Integrated ADS, Burbank’s system operators will be able to manage the available system resources to optimize system reliability while achieving the most economic and sustainable energy supply portfolio.

MicroGrid and Energy Storage System COMPLETE DETAILS NEW PPT Abin Baby
A microgrid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (macrogrid). This single point of common coupling with the macrogrid can be disconnected. The microgrid can then function autonomously. Generation and loads in a microgrid are usually interconnected at low voltage. From the point of view of the grid operator, a connected microgrid can be controlled as if it were one entity.
Microgrid generation resources can include fuel cells, wind, solar, or other energy sources. The multiple dispersed generation sources and ability to isolate the microgrid from a larger network would provide highly reliable electric power. Produced heat from generation sources such as micro turbines could be used for local process heating or space heating, allowing flexible trade off between the needs for heat and electric power.
Goldwind is leveraging its expertise in wind turbines to develop microgrid solutions using renewable energy sources like wind and solar, along with energy storage technologies. It has installed microgrids at industrial parks and desalination plants in China. One microgrid uses a 2.5MW wind turbine, solar PV, batteries, and a diesel generator connected to an energy management system. Another site doubled its desalination capacity by expanding its microgrid with a 2.5MW wind turbine and batteries. Goldwind aims to continue installing more advanced microgrid systems using its control technologies.

Recording at https://youtu.be/3YN4F8-G3RM
The electric vehicle penetration at global level is expected to surge in the coming years. While permanent magnet motors are convenient in terms of power density and efficiency, the use of rare earths is problematic for multiple reasons.
The ReFreeDrive project (www.refreedrive.eu), funded by the European Commission, has pushed the boundary of two motor technologies which do not use any critical raw material at all: induction with copper rotor and synchronous reluctance. The specific torque is increased by 30%, motor losses reduced by 50% and costs by 15%, while delivering a solution feasible for mass production.
In this webinar IFPEN Energies Nouvelles and University of Aquila will explain in detail the control strategies and electric drive design of induction and synchronous reluctance motors for e-mobility.

The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
