Abstract

Renewable energy sources were introduced as an alternative to fossil fuel sources to make electricity generation cleaner. However, today’s renewable energy markets face a number of limitations, such as inflexible pricing models and inaccurate consumption information. These limitations can be addressed with a decentralized marketplace architecture. Such architecture requires a mechanism to guarantee that all marketplace operations are executed according to predefined rules and regulations. One of the ways to establish such a mechanism is blockchain technology. This work defines a decentralized blockchain-based peer-to-peer (P2P) energy marketplace which addresses actors’ privacy and the performance of consensus mechanisms. The defined marketplace utilizes private permissioned Ethereum-based blockchain client Hyperledger Besu (HB) and its smart contracts to automate the P2P trade settlement process. Also, to make the marketplace compliant with energy trade regulations, it includes the regulator actor, which manages the issue and consumption of guarantees of origin and certifies the renewable energy sources used to generate traded electricity. Finally, the proposed marketplace incorporates privacy-preserving features, allowing it to generate private transactions and store them within a designated group of actors. Performance evaluation results of HB-based marketplace with three main consensus mechanisms for private networks, i.e., Clique, IBFT 2.0, and QBFT, demonstrate a lower throughput than another popular private permissioned blockchain platform Hyperledger Fabric (HF). However, the lower throughput is a side effect of the Byzantine Fault Tolerant characteristics of HB’s consensus mechanisms, i.e., IBFT 2.0 and QBFT, which provide increased security compared to HF’s Crash Fault Tolerant consensus RAFT.

共识机制在支持隐私的分散式可再生能源市场中的性能和可扩展性
可再生能源的引入是为了替代化石燃料,使发电更加清洁。然而,当今的可再生能源市场面临着许多限制,如定价模式不灵活、消费信息不准确等。这些限制可以通过分散的市场架构来解决。这种架构需要一种机制来保证所有市场运作都按照预定义的规则和条例执行。建立这种机制的方法之一就是区块链技术。这项工作定义了一个基于区块链的去中心化点对点(P2P)能源市场,它解决了参与者的隐私和共识机制的性能问题。所定义的市场利用基于以太坊的私有许可区块链客户端 Hyperledger Besu(HB)及其智能合约来自动执行 P2P 交易结算流程。此外,为了使市场符合能源贸易法规,市场还包括监管机构,负责管理原产地保证书的签发和消费,并对用于产生交易电力的可再生能源进行认证。最后,拟议的市场还具有隐私保护功能,允许生成私人交易并将其存储在指定的行为者群体中。基于 HB 市场的性能评估结果表明,与另一种流行的私有许可区块链平台 Hyperledger Fabric(HF)相比,基于 HB 市场的三种主要私有网络共识机制(即 Clique、IBFT 2.0 和 QBFT)的吞吐量较低。然而,较低的吞吐量是 HB 共识机制(即 IBFT 2.0 和 QBFT)的拜占庭容错特性的副作用,与 HF 的碰撞容错共识 RAFT 相比,它提供了更高的安全性。

期刊介绍: Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
