Transforming Energy Networks via Peer to Peer Energy Trading: Potential of Game Theoretic Approaches
Peer-to-peer (P2P) energy trading has emerged as a next-generation energy
management mechanism for the smart grid that enables each prosumer of the
network to participate in energy trading with one another and the grid. This
poses a significant challenge in terms of modeling the decision-making process
of each participant with conflicting interest and motivating prosumers to
participate in energy trading and to cooperate, if necessary, for achieving
different energy management goals. Therefore, such decision-making process
needs to be built on solid mathematical and signal processing tools that can
ensure an efficient operation of the smart grid. This paper provides an
overview of the use of game theoretic approaches for P2P energy trading as a
feasible and effective means of energy management. As such, we discuss various
games and auction theoretic approaches by following a systematic classification
to provide information on the importance of game theory for smart energy
research. Then, the paper focuses on the P2P energy trading describing its key
features and giving an introduction to an existing P2P testbed. Further, the
paper zooms into the detail of some specific game and auction theoretic models
that have recently been used in P2P energy trading and discusses some important
finding of these schemes.Comment: 38 pages, single column, double spac
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
