摘　　要：为应对售电侧放开后需求响应资源参与投标竞价过程中的复杂交易安全性,针对多级交易链中存在的潜在风险,探索区块链智能合约在需求响应投标交易中的应用方法,设计一种在非可信环境下的多级投标竞价链式信息传递安全机制。通过智能合约实现多级DR-BD链的同态安全交易,可以在无需公开参与方隐私数据、不泄露用户投标信息的条件下完成交易,同时也为参与交易的实体提供完整交易链条的有效性校验,可满足需求响应投标快速交易的安全性需求。同时还扩展了OpenA DR2.0b协议以及交易节点的合约更新运算规则,并给出该方法在现有技术框架下的实现方式。In response to security problem during complex bidding transaction after the opening of retail electricity market, this paper explored the smart contract application of block chain for the demand response resource participant in the bidding transaction, which can efficiently solve the potential risk within the multi-level trading chain. The multi-level homomorphic secure transaction mode of multi-level DR-BD chain was implemented with smart contract without the need to disclose the privacy data and the user＇s bidding information. Open ADR2.0 b specification and contract update rules were extended for the trading process to guarantee the unpublished trader privacy and user bidding information in the public network. The verification of effectiveness of bidding chain for participated utility can be achieved to fulfill the requirement of fast demand response bidding security.
