摘要：
Blockchain provides practical technical support for peer-to-peer（P2P） electricity trading in active energy agent （AEA） communities. However，the traditional rights confirmation and storage schemes are difficult to meet the personalized and diversified trading needs of AEA communities. For this purpose，non-fungible tokens（NFTs） are introduced to correspond one-to-one with P2P trading orders，and differentiated physical energy assets are mapped into digital assets on blockchain，which are transferred from the electricity sellers to the buyers along with the electricity trading. The trading process adopts the combination of on-chain and off-chain. Off the blockchain，the multi-dimensional willingness-based bidding algorithm is used to match the P2P electricity trading orders. On the blockchain，the electricity sellers issue NFTs according to the trading orders and the electricity buyers subscribe them. NFTs realize the value representation and value transfer of physical electricity assets in the digital world，which can be used as the deposit of future electricity delivery and electricity fee settlement. The NFT smart contract based on Ethereum is written and the test deployment is completed. The data distributed storage scheme based on interplanetary file system and data viewing scheme based on OpenSea platform are designed. The numerical simulation of a 29-bus AEA community verifies the effectiveness of the proposed scheme. © 2023 Electric Power Automation Equipment Press. All rights reserved.
