基于非同质化代币的主动能量体社群点对点电能交易

区块链为主动能量体(AEA)社群的点对点(P2P)电能交易提供了现实的技术支撑，但经典的确权和存证方案难以满足AEA社群中个性化、差异化的交易需求，为此引入非同质化代币(NFT)与P2P交易订单一一对应，将差异化的实体电能资产映射为区块链上的数字资产，并随电能交易由售电方向购电方转让。交易过程采用链上链下相结合的方式：在区块链下，使用基于多维意愿的竞价算法进行P2P电能交易订单的匹配；在区块链上，售电方根据交易订单发行NFT并由购电方认购，实现了实体电能资产在数字世界中的价值表示和价值转移，可作为日后电能交付和电费结算存证。编写了基于以太坊的NFT智能合约并完成测试部署，设计了基于星际文件系统的数据分布式存储和基于OpenSea平台的数据查看方案。针对一个29节点的AEA社群进行数值仿真，结果验证了所设计方案的有效性。

Peer-to-peer electricity trading of active energy agent community based on non-fungible tokens

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 electri-city 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 accor-ding 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.
