Uno strumento virtuale per il monitoraggio e il controllo di un impianto fotovoltaico a concentrazione
2014
In questa memoria si presenta una sintesi delle attività condotte nell'ambito del progetto SERPICO ("Sviluppo E Realizzazione di Prototipi di Inverter per impianti fotovoltaici a Concentrazione", PO-FESR Sicilia 2007-2013, Misura 4.1.1.2). Il progetto ha riguardato lo sviluppo di un prototipo di impianto fotovoltaico-termico a concentrazione e del relativo sistema di monitoraggio e controllo. Tale sistema permette di acquisire le quantità sia elettriche che termiche. Inoltre esso implementa un algoritmo per l'inseguimento solare utilizzato per ottimizzare la produzione di potenza.
Characterization of IP-Based Communication for Smart Grid Using Software-Defined Networking
2018
The smart grid (SG) approach is based on a strong interaction between the network communication infrastructure and the power grid. Usually the management of the infrastructure is done by the distribution system operators (DSOs) that are worried about the increasing managing complexity due to the presence of increasing number of distributed energy resources and electrical vehicles. The use of software-defined networking (SDN) may simplify the network configuration and management for DSO, as highlighted from previous research works. The objective of this paper is to introduce and characterize an internet protocol (IP)-based communication architecture with specialized SDN bridges operating als…
Cabine secondarie: nodi intelligenti e sicuri delle smart grid
2015
Nel futuro panorama delle Smart Grid, le cabine secondarie assumeranno il ruolo di nodi intelligenti e sicuri della rete di distribuzione, integrando diverse soluzioni innovative di monitoraggio, comunicazione, controllo e richiedendo maggiori caratteristiche di sicurezza come proposto nei due progetti di ricerca REIPERSEI e NewCabElarc

A PC-based instrument for automatic monitoring and control of a CPVT power plant
2014
A PC-based instrument has been developed for the monitoring and control of a concentrated photovoltaic and thermal (CPVT) power plant. The instrument allows acquiring both electrical and thermal quantities. Moreover it implements the solar tracking algorithm used to optimize the power production.
Sistemi di comunicazione e dispositivi di interfaccia per l'integrazione della generazione distribuita nelle smart grids
2014
L'integrazione della generazione distribuita (GD) nelle reti elettriche di distribuzione a media e bassa tensione uno degli elementi chiave per il pieno sfruttamento delle fonti energetiche rinnovabili (FER). Ci implica un ripensamento della gestione e del controllo delle reti elettriche , che devono passare da sistemi " passivi ", con flussi di potenza unidirezionali e un numero limitato di funzioni di monitoraggio e automazione, a reti attive e intelligenti (Òsmart gridsÒ). In tali sistemi, i flussi di potenza possono essere bi-direzionali e, se non correttamente gestiti, possono causare situazioni critiche, quali ad es. problemi di stabilit e di controllo della rete o funzionamento i…
PQ and Harmonic Assessment Issues on Low-Cost Smart Metering Platforms: A Case Study
2020
This paper presents a feasibility study on how to implement power quality (PQ) metrics in a low-cost smart metering platform. The study is aimed at verifying the possibility of implementing PQ monitoring in distribution networks without replacing existing smart metering devices or adding new modules for PQ measurements, thus zeroing the installation costs. To this aim, an electronic board, currently used for remote energy metering, was chosen as a case study, specifically the STCOMET platform. Starting from the specifications of this device, the possibility of implementing power quality metrics is investigated in order to verify if compliance with standard requirements for PQ instruments ca…
Impact of non-programmable distributed generation in an islanded microgrid: the case study of Ustica
2022
The paper presents a systematic analysis of nonprogrammable distributed generation impact in an islanded microgrid Different issues have been analyzed, with a special focus on the most significant ones in a small islanded network. To this aim, the case study of Ustica island was considered A digital twin of the MV network was developed starting from the network topology data and the power measurement acquired in each secondary substation. Simulations were then performed in the hypothesis of a large increment of distributed generation installation into the network. A discussion is then reported on which are the main technical issues to be faced in the considered case study.
The dynamic concept of humor : Erich Fromm and the possibility of humane humor
2016
This dissertation focuses on the social philosophy of humor from the viewpoint of Erich Fromm’s critical humanistic thinking. The work consists of an introduction and four individual articles. The introduction discusses Fromm’s theories in relation to the phenomenon of humor to provide a basis for the articles. The central aim is to understand the dynamic nature of humor and how it is related to the problem of being a paradoxical creature, that is, a human being. It is claimed that humor has to be analyzed and interpreted in a unique historical and cultural situation. The first article discusses Fromm’s concept of social character to offer a theoretical tool to understand how deeply humor i…
