“…A two-stage non-cooperative game model was developed in [130] for efficient energy sharing among smart buildings, and it is solved by alternating direction method of multipliers. Decomposition approach was used in [131] to solve a distributed optimal power flow problem for efficient energy trading among peers.…”

Prosumer concept and digitilization offer the exciting potential of microgrid transactive energy systems at distribution level for reducing transmission losses, decreasing electric infrastructure expenditure, improving reliability, enhancing local energy use, and minimizing customers' electricity bills. Distributed energy resources, demand response, distributed ledger technologies, and local energy markets are integral parts of transaction energy system for emergence of decentralized smart grid system. Hence, this paper discusses transactive energy concept and proposes seven functional layers architecture for designing transactive energy system. The proposed architecture is compared with practical case study of Brooklyn microgrid. Moreover, this paper reviews the existing architectures and explains the widely known distributed ledger technologies (blockchain, directed acyclic graph, hashgraph, holochain, and tempo) alongwith their advantages and challenges. The local energy market concept is presented and critically analyzed for energy trade within a transactive energy system. This paper also reviews the potential and challenges of peer-topeer and community-based energy markets. Proposed architecture and analytical review of distributed ledger technologies and local energy markets pave the way for advanced research and industrialization of transactive energy systems.

“…For example, users cheat high subsidies by faking their own transactions and electricity usage data [51]. Furthermore, the distributed energy sources have small capacity and random output, so it is difficult to be directly connected with power grid [52]. Many scholars have proposed the control concept of virtual power plants to reduce the impact of these problems by aggregating distributed energy sources and centrally managing them [53,54].…”

In order to ensure the information security, most of the important information including the data of advanced metering infrastructure (AMI) in the energy internet is currently transmitted and exchanged through the intranet or the carrier communication. The former increases the cost of network construction, and the latter is susceptible to interference and attacks in the process of information dissemination. The blockchain is an emerging decentralized architecture and distributed computing paradigm. Under the premise that these nodes do not need mutual trust, the blockchain can implement trusted peer-to-peer communication for protecting the important information by adopting distributed consensus mechanisms, encryption algorithms, point-to-point transmission and smart contracts. In response to the above issues, this paper firstly analyzes the information security problems existing in the energy internet from the four perspectives of system control layer, device access, market transaction and user privacy. Then blockchain technology is introduced, and its working principles and technical characteristics are analyzed. Based on the technical characteristics, we propose the multilevel and multichain information transmission model for the weak centralization of scheduling and the decentralization of transaction. Furthermore, we discuss that the information transmission model helps solve some of the information security issues from the four perspectives of system control, device access, market transaction and user privacy. Application examples are used to illustrate the technical features that benefited from the blockchain for the information security of the energy internet.

“…. , n, then break; end if end for WCDL and EVs compute the P2P energy trading price λ by (14); WCDL and EVs compute the P2P energy trading amount by (10); works should be conducted for the latter general scenarios. It is anticipated that in many-seller-many-buyer scenarios, the number of iterations for the consensus negotiations would be smaller than that in the current paper, due to the smaller value of the second-largest eigenvalue of the Laplacian matrix of the network graph.…”

“…Accordingly, different approaches have been proposed as P2P energy trading mechanisms. For example, game theory was used in [9]- [14], bilateral contracts were investigated in [15]- [18], multi-class energy management was introduced in [19]. Next, continuous double auction was presented in [20], supply-demand ratio based pricing was utilized in [21], mixed performance indexes were considered in [22], federated P2P energy systems were proposed in [23].…”

This paper investigates the problem of bidirectional energy exchange between electric vehicles (EVs) and road lanes embedded with wireless power transfer technologies called wireless chargingdischarging lanes (WCDLs). As such, EVs could provide better services to the grid, especially for balancing the energy supply-demand, while bringing convenience for EV users, because no cables and EV stops are needed. To enable this EV-WCDL energy exchange, a novel decentralized peer-to-peer (P2P) trading mechanism is proposed, in which EVs directly negotiate with a WCDL to reach consensus on the energy price and amounts to be traded. Those energy price and amounts are solutions of an optimization problem aiming at optimizing private cost functions of EVs and WCDL. The negotiation process between EVs and WCDL is secured by a privacy-preserving consensus protocol. Further, to assure successful trading with desired energy price and amounts, an analytical and systematic method is proposed to select cost function parameters by EVs and WCDL in a decentralized manner. Simulations are then carried out to validate the developed theoretical results, which confirm the effectiveness and scalability of the proposed algorithm.
