摘要

在智能电网中，智能电表存储了大量私人数据，如实时用电数据。然而，由于人为攻击，它们可能变成恶意节点，导致数据泄漏和不可靠的交易。此外，电力交易过程中还存在计算成本过高和吞吐量受限等重大问题。为了提高电力交易的可信度和效率，我们创新性地提出了一种实时点对点电力交易模型（RMCT），将信誉机制和多链技术整合到区块链环境中。首先，在RMCT中，设计了基于用户行为管理的信誉机制，以有效减少分布式电力交易过程中的恶意行为，提高交易的合规性。其次，首次提出多链模型，动态电量单价链与用户实时用电链实时交互，实现用户与主网之间高效的电费结算。充分的实验结果和分析证明了 RMCT 的有效性和性能。此外，还对 RMCT 和相关工作进行了全面的定性比较，以充分验证其可行性和创新性。

RMCT: Distributed electricity transaction based on reputation mechanism and multi-chain technology in blockchain environment

In smart grids, large amounts of private data, such as real-time electricity consumption data, are stored by smart meters. However, they can be turned into malicious nodes due to human attacks, resulting in data leakage and unreliable transactions. Additionally, significant issues in power transaction processes include excessive computational costs and restricted throughput. To enhance the trustworthiness and efficiency of power trading, we innovatively propose a real-time peer-to-peer power trading model (RMCT), integrating reputation mechanism and multi-chain technology in blockchain environment. Firstly, in RMCT, a reputation mechanism is designed based on user behavior management to effectively reduce malicious behaviors and improve transaction compliance in the distributed power trading process. Secondly, a multi-chain model is firstly proposed where the dynamic electricity unit price chain interacts in real-time with the user’s real-time electricity consumption chain, enabling efficient electricity billing settlement between the user and the main grid. The validity and performance of RMCT are demonstrated by adequate experimental results and analysis. Additionally, a comprehensive qualitative comparison between RMCT and related work is conducted to fully verify its feasibility and innovation.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
