摘要
为适应电力市场化改革趋势实现支持复杂交易形式的电力交易系统,基于区块链技术提出一种分布式电力竞价交易算法。将竞价交易分为出价及应价2种交易,针对同一笔出价交易,允许多笔应价交易存在,并由节点服务器通过对所有应价交易进行排序比价决定胜出交易。基于有序聚合签名对交易顺序及交易内容进行验证,确保交易的真实性,同时利用保序加密技术对交易内容进行保护,确保交易隐私数据的机密性。在此基础上,通过区块链存储所有交易,确保交易的不可篡改性。实验结果表明,该算法可以有效提高交易生成及验证效率,快速达成安全的电力竞价交易。
To embrace the marketization reform of Chinese power system,this paper proposes a blockchain-based algorithm for distributed power auction transaction,so as to realize a power bidding system that supports complex forms of transactions.The algorithm divides relevant transactions into two types:offering and responding.Multiple responders are allowed to compete for an offering,and a node server will sort the responders by price to decide the winner.The order and content of transactions are verified based on sequential aggregate signature to ensure the authenticity of transactions.Also,order-preserving encryption is adopted to protect the content of a transaction,thus ensuring the confidentiality of private data.On this basis,all transactions data are stored by using blockchain technologies to ensure the transactions are tampering-resistant.Experimental results show that the proposed algorithm can improve the efficiency of transactions generation and verification,enabling quick and safe power bidding transactions.
