Blockchain electricity trading using tokenised power delivery contracts. ESRI Working Paper No. 649 December 2019
This paper proposes a new mechanism for forward selling renewable electricity generation. In this transactive
framework, a wind or solar farm may directly sell to consumers a claim on their future power output in the form of nonfungible
blockchain tokens. Using the flexibility of smart contract code, which executes irrevocably on a blockchain, the realised
generation levels will offset the token holders’ electricity consumption in near real-time. To elucidate the flexibility offered by
such smart contracts, two ways of structuring these power delivery instruments are considered: firstly, an exotic tranched
system, where more senior tokens holders enjoy priority claims on power, as compared against a simpler pro-rata scheme,
where the realised output of a generator is equally apportioned between token holders. A notional market simulation is
provided to explore whether, for instance, consumers could exploit the flatter power delivery profiles of more senior tranches to
better schedule their responsive demands
Peer-to-peer and community-based markets: A comprehensive review
The advent of more proactive consumers, the so-called "prosumers", with
production and storage capabilities, is empowering the consumers and bringing
new opportunities and challenges to the operation of power systems in a market
environment. Recently, a novel proposal for the design and operation of
electricity markets has emerged: these so-called peer-to-peer (P2P) electricity
markets conceptually allow the prosumers to directly share their electrical
energy and investment. Such P2P markets rely on a consumer-centric and
bottom-up perspective by giving the opportunity to consumers to freely choose
the way they are to source their electric energy. A community can also be
formed by prosumers who want to collaborate, or in terms of operational energy
management. This paper contributes with an overview of these new P2P markets
that starts with the motivation, challenges, market designs moving to the
potential future developments in this field, providing recommendations while
considering a test-case
Decentralized Finance – A Systematic Literature Review and Research Directions
Decentralized Finance (DeFi) is the (r)evolutionary movement to create a solely code-based, intermediary-independent financial system—a movement which has grown from 104bn in assets locked in the last three years. We present the first systematic literature review of the yet fragmented DeFi research field. By identifying, analyzing, and integrating 83 peer-reviewed DeFi-related publications, our results contribute fivefold. First, we confirm the increasing growth of academic DeFi publications through systematic analysis. Second, we frame DeFi-related literature into three levels of abstraction (micro, meso, and macro) and seven subcategories. Third, we identify Ethereum as the blockchain in main academic focus. Fourth, we show that prototyping is the dominant research method applied whereas only one paper has used primary research data. Fifth, we derive four prioritized research avenues, namely concerning i) DeFi protocol interaction and aggregation platforms, ii) decentralized off-chain data integration to DeFi, iii) DeFi agents, and iv) regulation
