Energy Consumption/Generation Model: Data collected, architecture conceived and scenarios addressed

2014

The paper provides the data collected, the architecture and the conceived scenarios for the development of an Energy Consumptions/Generations Model. This model is suitable for the modeling, processing, analyzing and forecasting of energy consumption and generation at home, building and neighborhood level. Data are from the Census Returns, Electoral Registers & Council of the real town of Loughborough (U.K.). The architecture conceived describes the real distribution system which supplies the Loughborough geographic area. The scenarios considered take into account both traditional dwellings (equipped with dumb appliances) and new dwellings (equipped with smart networked appliances) © 2014 IE…

A single-point strategy based on IEEE 1459-2000 for the Detection of Dominant Harmonic Sources in Power Systems

2008

This paper deals with a novel single-point strategy for the detection of harmonic sources in power systems. It is an enhancement of a previous strategy, developed by authors, which is based on the IEEE Std. 1459-2000 approach. In the paper, the effectiveness of the strategy is investigated, by means of simulation tests, which were carried out on a IEEE standard three-phase test power system. The analysis is carried out by considering also the presence of the measurement transducers.

A resilient distributed measurement system for smart grid application

2020

Since the production of energy from renewable energy sources is strongly increasing, the migration from the classical electric grid toward the smart grid is becoming a reality. Distribution System Operators, along with the control of the entire network and its stability, need to address the security and the reliability of the communication channels and the data itself. In this paper a solution is proposed to address these issues. It is based on a distributed measurement system that relies on a wireless network as well as a redundant Power Line communication system in order to transfer the electrical measures to a centralized SCADA server. The collected data are used to run a power flow algo…

An Innovative dosimeter based on a floating Gate sensor

2019

This work describes the development of a new method for recording radiation exposure by using a passive dosimeter based on a Floating Gate CMOS sensor. The floating Gate sensors based on the MOS structure discharge allow the construction of compact and cost-efficient dosimeters, realized in VLSI CMOS technology, for use in integration mode in various applications, in particular in radiotherapy.

Studio di modelli equivalenti per la simulazione con il codice PENELOPE della risposta in efficienza di un rivelatore HPGe

2017

La simulazione della risposta di un rivelatore HPGe con l’impiego di codici Monte Carlo è una tecnica ormai diffusamente impiegata e particolarmente utile per la valutazione di efficienze quando non sono disponibili standards di calibrazione con stessa forma e composizione del campione in esame. Il risultato della simulazione dipende dalla conoscenza più o meno dettagliata delle caratteristiche del rivelatore, atte a definire un “modello” dello stesso. Per evidenziare anche quelle parti non definite nella certificazione del costruttore, solitamente si effettua una radiografia del rivelatore fatta eccezione per i casi in cui non è realizzabile pena lo smontaggio della struttura di schermatur…

PV Reconfiguration Systems: a Technical and Economic Study

2017

Dynamical electrical array reconfiguration strategies for grid-connected PV systems have been proposed as solution to improve energy production due to the mismatch effect of PV plants during partial shading conditions. Strategies are based on the use of dynamic connections between PV panels given by the employment of switches that allow for each panel the series, parallel or exclusion connections, physically changing the electrical connections between the related PV modules, consequentially modifying the layout of the plant. Usually the cost of the dynamic matrix is not taken into account. This novel work evaluates the economic advantages obtained by the use of reconfiguration strategies in…

Measurements methodology for the reliability evaluation of intelligent power modules

2014

The paper describes a measurement methodology for the reliability evaluation of new intelligent power electronics modules (IPMs). In particular, the evaluation of the IPMs immunity to radio frequency conducted disturbances has been performed, at different operating thermal conditions, designing a suitable measurement set up in a shielded room. Moreover, the thermal performances of the devices have been analyzed, setting up a proper experimental test bench. The measurements procedures are detailed described. © 2014 IEEE.

Electron paramagnetic resonance line shape investigation of the Si-29 hyperfine doublet of the E'γ center in a-SiO2

2007

We report an experimental study by electron paramagnetic resonance (EPR) spectroscopy of the E′γ center and of its hyperfine structure, consisting in a pair of lines split by 42 mT. Our results show that two types of E′γ centers can be distinguished on the basis of the EPR line shapes of their main resonance line and hyperfine structure. (© 2007 WILEY-VCH Verlag GmbH & Co.
