Energy management systems for the operation of\ud distributed energy resources, distribution storage devices, and\ud responsive loads will be embedded in distribution management\ud systems (DMSs) as advanced functions that rely on accurate input\ud data and fast communication signals. For a proper DMS design,\ud the impact of the state estimation uncertainties and of the communication\ud system delays should be evaluated. The paper presents\ud an integrated software package for the cyber-physical simulation\ud of DMS taking into account the accuracy of state estimation and\ud measurements. The effectiveness of a wireless Wi-Max communication\ud system has been tested on the rural Italian representative\ud network produced by the research project ATLANTIDE. Results\ud proved the need of cosimulation packages in modern distribution\ud systems

Future liquid-argon DarkSide-20k and Argo detectors, designed for direct dark matter search, will be sensitive also to core-collapse supernova neutrinos, via coherent elastic neutrino-nucleus scattering. This interaction channel is flavor-insensitive with a high-cross section, enabling for a high-statistics neutrino detection with target masses of ∼50 t and ∼360 t for DarkSide-20k and Argo respectively. Thanks to the low-energy threshold of ∼0.5 keV nr achievable by exploiting the ionization channel, DarkSide-20k and Argo have the potential to discover supernova bursts throughout our galaxy and up to the Small Magellanic Cloud, respectively, assuming a 11-M progenitor star. We report also on the sensitivity to the neutronization burst, whose electron neutrino flux is suppressed by oscillations when detected via charged current and elastic scattering. Finally, the accuracies in the reconstruction of the average and total neutrino energy in the different phases of the supernova burst, as well as its time profile, are also discussed, taking into account the expected background and the detector response.

Design and construction of a new detector to measure ultra low radioactiveisotope contamination of argon Article (Accepted Version) http://sro.sussex.ac.uk

This paper presents a comparison between the two main classes of Weighted Least Squares (WLS) state estimators used in distribution systems: state estimators based on node voltage state variables and estimators based on a state expressed in terms of branch-currents. In particular, the actual accuracy achieved for the estimated quantities by these estimators and their modified versions is analysed in details along with their performance, considering different types of real-time measure- ments (traditional or phasorial), different configurations of the measurement system and the impact of the network parameters uncertainty. Results obtained on two distribution networks with different scale, 18-bus and 95-bus, are presented and discussed

DarkSide uses a dual-phase Liquid Argon Time Projection Chamber (TPC) to search for WIMP dark matter. The paper will present the latest result on the search for low mass (M W IMP < 20 Gev/c 2) and high mass (M W IMP > 100 Gev/c 2) WIMPs from the current experiment, DarkSide-50, running since mid 2015 a 50-kg-active-mass TPC, filled with argon from an underground source. The next stage of the DarkSide program will be a new generation experiment involving a global collaboration from all the current Argon based experiments. DarkSide-20k, is designed as a 20-tonne fiducial mass TPC with SiPM based photosensors, expected to be free of any background for an exposure of >100 ton x years. Like its predecessor DarkSide-20k will be housed at the Gran Sasso (LNGS) underground laboratory, and it is expected to attain a WIMPnucleon cross section exclusion sensitivity of 10 −47 cm 2 for a WIMP mass of 1 TeV /c 2 in a 5 yr run. A subsequent objective, towards the end of the next decade, will be the construction of the ultimate detector, ARGO, with a 300 t fiducial mass to push the sensitivity to the neutrino floor region for high mass WIMPs. The combination of the three experiments, part of a single family, will cover completely the WIMP hypothesis from 1 GeV /c 2 to several hundreds of TeV /c 2 masses.
