I sistemi di trasferimento di potenza wireless (WPT) induttivi risonanti costituiscono una soluzione tecnologica promettente per la ricarica automatizzata dei veicoli elettrici, eliminando il contatto galvanico tra infrastruttura di ricarica e veicolo [1], [2]. In questo lavoro di tesi si affronta la progettazione, il dimensionamento analitico e la validazione in simulazione di un sistema WPT stazionario di classe WPT1 (3,7 kW, 85 kHz, conforme allo standard SAE J2954 [4]), basato sulla topol...
Analisi di un alternatore motociclistico a rotore esterno attualmente in produzione da Ducati Energia e progettazione di soluzioni alternative senza terre rare
La necessità crescente di utilizzare tecniche di alimentazione wireless ha aperto la strada a nuove modalità per il trasferimento di potenza. In questo scenario, accanto al più tradizionale accoppiamento induttivo, è di interesse la trasmissione di energia attraverso onde sonore. Il trasferimento di potenza acustica wireless rispetto ad altri metodi può rappresentare la migliore alternativa in tutte quelle situazioni in cui sono richieste dimensioni ridotte del sistema, in cui è necessaria un...
La presente tesi analizza i sistemi di accumulo elettrochimico a batteria (Battery Energy Storage System, BESS), con riferimento alle applicazioni Commercial & Industrial (C&I) e Utility Scale. Dopo un inquadramento della tecnologia (architettura, chimiche elettrochimiche, parametri prestazionali) e una mappatura delle modalità di impiego e dei canali di valorizzazione economica accessibili a un BESS, il lavoro sviluppa uno strumento proprietario di dimensionamento tecnico-economico per appli...
With the increasing penetration of Inverter-Based Resources in modern power systems, system stability and power quality have emerged as critical issues. This complexity is primarily driven by the active control mechanisms present at both the source and the load side and is further compounded by the growing proliferation of Distributed Energy Resources across distribution networks. Consequently, identifying potential instabilities and resonance phenomena triggered by these dynamic interactions...
This thesis presents a novel multi-objective topology optimisation (TO) framework for electromagnetic devices, designed to overcome the prohibitive computational costs of traditional methods. By combining a Differential Evolution (DE) algorithm with Normalised Gaussian Network (NGNet) parametrization, this approach reduces the dimensionality of the design space and naturally generates smooth, manufacturable topologies without explicit spatial filtering. The framework is applied to minimise th...
The Italian and European electricity generation mix is becoming increasingly dominated by renewable sources, driven by the need to reduce greenhouse gas emissions and pollutant levels. Photovoltaic generation is the leading technology in this transition: the maturity of the technology and the relocation of manufacturing outside Europe have lowered its cost to the point that plant sizes have grown steadily, from single-user installations to modern utility-scale photovoltaic fields.
This growth...
The increasing adoption of electric vehicles and the growing share of electricity generated from
renewable energy sources make smart charging infrastructure increasingly important. These
systems can meet the charging needs of electric vehicles while also supporting the stability and
flexibility of the power grid. In this context, Vehicle-to-Grid (V2G) technology is a promising
solution, as it enables a bidirectional exchange of energy between electric vehicles and the grid.
This work analyses...
The introduction of next-generation per- and polyfluoroalkyl substances (PFAS), including perfluoropentanoic acid (PFPeA) and hexafluoropropylene oxide dimer acid (GenX), has raised ecotoxicological concerns due to their persistence and occurrence in coastal ecosystems. These transitional environments are also increasingly affected by climate- driven salinity fluctuations associated with extreme precipitation. This study assessed the effects of GenX and PFPeA, individually and as a mixture (M...
The present master thesis addressed the need to improve the environmental sustainability of intensive Penaeus vannamei production in Europe by addressing one of the major limitations of the BFT system, the accumulation of nutrients, in particular nitrate and phosphate. The improve of the management of aerobic denitrification strategies could contribute to the development of more stable, water-efficient and environmentally sustainable shrimp farming systems adapted to European conditions.
The ...
