A Blockchain-based Platform for Positive Energy Districts

2022

The reduction of climate change effects (mitigation) is now mainly driven by the limitation of CO2 emissions which is currently becoming increasingly necessary and urgent to achieve. In this context, within the past Horizon 2020 program, the Urban Europe Joint Programming Initiative aimed to promote the development and deployment of at least 100 Positive Energy Districts by 2025. The latter are flexible, energy-efficient urban areas or groups of buildings that produce zero net CO2 emissions and actively manage annual renewable energy surplus production at the local or regional level. As they are connected to the electric power system, Positive Energy Districts have the ability to offer flex…

Experimental Tests

2022

This chapter presents the outcomes of the experimental implementation of the architecture described in Chap. 4 running a hardware testbed for the emulation of domestic electrical load profiles. Besides it shows how this experimental scenario integrates both with the legacy metering architecture and with the blockchain platform. Finally, the integrated use with an Energy Management System designed on purpose is also described with the aim of ensuring intervention and automating the end user’s response to a DR event.

A blockchain platform for Demand Response in Mediterranean islands: a smart contract for remuneration

2022

The Blorin project started at the end of 2019 to support the implementation of a blockchain platform to support the energy services provision from end users by means of Demand Response and Vehicle to Grid programs. The experimental part of the project is being carried out on two Mediterranean islands and inside the University campus in Palermo. Customized smart contracts have been designed to support the active participation of end users to regulation services for the two weak electrical grids of the islands in the view of a deep penetration of renewable energy in the two energy systems. In particular, the smart contract for remuneration accounts for the very special energy situation of isl…

A Technical Approach to the Energy Blockchain in Microgrids

2018

The present paper considers some technical issues related to the “energy blockchain” paradigm applied to microgrids. In particular, what appears from the study is that the superposition of energy transactions in a microgrid creates a variation of the power losses in all the branches of the microgrid. Traditional power losses allocation in distribution systems takes into account only generators while, in this paper, a real-time attribution of power losses to each transaction involving one generator and one load node is done by defining some suitable indices. Besides, the presence of P–V nodes increases the level of reactive flows and provides a more complex technical perspective. For this re…

Riflessioni a margine dell’ordinanza cautelare del 26 novembre 2021 del Tribunale di Gorizia: greenwashing tra concorrenza sleale e diritto del consu…

2022

La pubblicizzazione sul mercato di prodotti ecofriendly non di rado si è rivelata frutto di pratiche scorrette di c.d. greenwashing, ciò consistendo in ipotesi di concorrenza sleale capaci di alterare i sistemi competitivi del libero mercato e ledere il diritto dei consumatori all’acquisto consapevole. Simili atti sono oggi sanzionati ricorrendo ad inibitorie e a comunicazioni pubbliche in cui l’impresa infedele informa i propri consumatori circa l’ingannevolezza dei comportamenti posti in essere. In tale ambito, che in primo luogo interessa il settore agroalimentare, si inserisce l’ordinanza cautelare del 26 novembre 2021 del Tribunale di Gorizia. Il ricorso a disciplinari di produzione ba…

Cryptocurrencies, Cybersecurity and Bankruptcy Law: How Global Issues Are Globalizing National Remedies

2020

The market for cryptocurrencies is interspersed with cases of loss, theft and fraud and a new transnational practice in bankruptcy law is emerging whereby cryptocurrency exchanges compensate the injured users on a collective basis. This paper will argue: first, that this trend has transplanted into Asia and Europe the US idea according to which bankruptcy law can be employed to avoid mass litigation; secondly, that this trend has transcended the debate about the characterization of digital assets, including the concerns of those scholars who maintain that digital coins cannot be objects of property; and thirdly that – since this practice follows the pattern of so-called restorative justice …

Talking Blockchains: The Perspective of a Database Researcher

2021

There are few topics out there, that seem to create as much confusion and discussion as blockchains. This has a multitude of reasons: (1) A large number of drastically different concepts and systems are unified under the very broad term "blockchain". (2) The topic touches a variety of different fields, including databases, distributed processing, networks, cryptography, and even economics. (3) There exists a large number of different applications of the technology.The goal of this paper is to simplify and structure the discussion of blockchain technology. We first introduce a simple formalization of the basic components, that appear again and again in a variety of blockchain systems. Second…

Clean air, technology, glocalization: how can we clean up the Planet with small little actions that resonate globally? Blockchain may be the answer

2022

Amongst the lessons that the Covid-19 pandemic has taught us, there is at least one lesson for each of these three words: clean air, technology and glocalization. Clean air: research has noticed a link between polluted air and the spread of the virus, in a game where the former helps the latter. Do we need further evidence that polluted air is bad? Technology: smart working, schools, everything during lockdown functions thanks to stable internet and connected devices. Glocalization: small actions can resonate, as a virus can spread if citizens move across countries or go out without wearing masks. To make sure we reach our goals – be them the UN Sustainable Development Goals, the thresholds…

Demand Response Service Certification and Customer Baseline Evaluation Using Blockchain Technology

2020

The use of Distributed Ledger Technologies such as Blockchain for certifying Demand Response services allows for the creation of a distributed system in which customers can communicate with the system operator to provide their flexibility, in a secure, transparent and traceable way. Blockchain technology also supports incentive mechanisms for users taking part in the service through the generation of utility tokens to recognize the user's contribution. This paper presents the experimental test of a novel methodology for Demand Response programs implementation by using the Blockchain technology. The latter is employed for defining a distributed Demand Response service and a new system for it…
