Abstract

A large number of individual power prosumers are emerging and participating in the regional energy internet (REI) with the rapid development of the power generation technology of distributed renewable energy. The increasing scale of the REI may bring challenges to the traditional centralized electricity trading and match platform in the REI. However, existing researches and realizations on blockchain based distributed electricity transaction platform adopts traditional mechanisms such as double auctions more, which may cause challenges in actual applications such as the match of clean energy is relatively difficult, the waste of electricity transmission is hard to be calculated, and the electricity seller cannot select the purchaser, etc. In this paper, a blockchain-based distributed controllable electricity transaction match system is designed and implemented to propose a feasible system to overcome the existing challenges. The automatic match of single transactions on the blockchain is implemented based on smart contract technology in the system, which avoids the interference of the number of transactions and the matching cycle on the matching speed of single transaction in the matching process. Experimental results indicated that compared with traditional solutions, the supply ratio of clean energy in the entire REI increased from 4.69% to 78.15% by adopting the proposed system, and the electricity transmission loss in the entire REI is reduced by 1.08%.

基于区块链的分布式可控电力交易匹配系统

随着分布式可再生能源发电技术的快速发展，大量个体电力产消者正在涌现并参与到区域能源互联网中。随着REI规模的不断扩大，传统的集中式REI电力交易撮合平台将面临挑战。然而，现有的基于区块链的分布式电力交易平台的研究和实现多采用双重拍卖等传统机制，在实际应用中可能会遇到清洁能源匹配相对困难、输电浪费难以计算、售电方无法选择购电方等挑战。本文设计并实现了一种基于区块链的分布式可控电力交易匹配系统，提出了一种可行的系统来克服现有的挑战。系统中基于智能合约技术实现了区块链上单笔交易的自动匹配，避免了匹配过程中交易数量和匹配周期对单笔交易匹配速度的干扰。实验结果表明，与传统方案相比，采用该方案后，整个区域清洁能源的供应比例由4.69%提高到78.15%，整个区域的输电损耗降低了1.08%。
