State-Of-The-Art and Prospects for Peer-To-Peer Transaction-Based Energy System

Abstract

Abstract:Transaction-based energy (TE) management and control has become an increasingly relevant topic, attracting considerable attention from industry and the research community alike. As a result, new techniques are emerging for its development and actualization. This paper presents a comprehensive review of TE involving peer-to-peer (P2P) energy trading and also covering the concept, enabling technologies, frameworks, active research efforts and the prospects of TE. The formulation of a common approach for TE management modelling is challenging given the diversity of circumstances of prosumers in terms of capacity, profiles and objectives. This has resulted in divergent opinions in the literature. The idea of this paper is therefore to explore these viewpoints and provide some perspectives on this burgeoning topic on P2P TE systems. This study identified that most of the techniques in the literature exclusively formulate energy trade problems as a game, an optimization problem or a variational inequality problem. It was also observed that none of the existing works has considered a unified messaging framework. This is a potential area for further investigation.

Internet of Things Security: A review on the RFID contactless security protocols

“…New applications, such as smart cities [34], [35], intelligent transport, and digital health services make use of the low-cost RFID technologies to achieve 9 seamless interaction between humans and their environment. In conclusion it has been within no doubt proven that while RFID contactless cards are quite useful for society, there are serious issues that must be addressed with the security and privacy of data and this action must be taken as soon as possible before any serious problems happens.…”

A coalition formation game framework for peer-to-peer energy trading

“…We assume that at any time slot t of the day, the generation of solar energy from prosumer n's solar panel is E n,pv (t), the amount of energy discharged from its battery is E n,dis (t), and the energy demand of prosumer n is E n,dem (t) = E n,hou (t) + E n,cha (t). 6 A prosumer n can sell E n,sur (t) either to the CPS or to other prosumers in set N \ {n} of the network and can buy E n,def (t) from either of them. Note that in (2) and (3) the surplus and deficiency are calculated respectively after a prosumer already charges it battery from its own generation and discharges the battery for its household demand.…”

“…Further, it is also important to note that, as the cooperative framework is designed, the prosumers do not require to always use their batteries for participating in P2P trading. Rather, they can opportunistically choose to trade their battery energy when they find it beneficial for them by following (5) and (6) and still manage to reap a better (or at least equal) utility compared to the case without cooperation. For instance, as shown in Fig.…”

“…Consequently, a number of FiT schemes has been discontinued in recent times [5]. Meanwhile, a new energy trading paradigm, known as peer-to-peer (P2P) energy trading, has emerged recently [6].…”

Comparative Analysis of P2P Architectures for Energy Trading and Sharing

“…However, the connection/disconnection of DERs must be coordinated in order to maintain system integrity and seamless operation. A reliable communication system is needed to realise the exchange of monitoring and to control messages [2].…”
