基于双区块链的用电数据收集方案设计

智能电网基于生产计划调度的需要,会对用户实时用电信息进行采集,而细粒度的数据采集会带来用户的隐私暴露问题。针对这一问题,结合区块链技术提出了一个使用双区块链的用电信息存储链(Electricity ConsumptionInformation Storage Blockchain,ECISB)方案,在该方案中无需可信中心,其中一条链用于存储多用户的实时多维聚合用电数据,另一条链用于存储单用户的计费周期内用电量。双链设计既保证了智能电网实时用电数据采集的需要,又解决了传统方案中无法计量单用户用电量的问题。

Design of Power Consumption Data Collection Scheme Based on Double Blockchain

Based on the needs of production planning and scheduling, the smart grid collects real-time electricity usage information from users, while fine-grained data collection brings privacy issues to users. In response to this problem, this paper proposes an Electricity Consumption Information Storage Blockchain （ECISB） scheme based on blockchain technology, in which no trusted center is needed, and one chain is used for the multi-user real-time multi-dimensional aggregated power consumption data is stored, and the other chain is used to store the power consumption in a single-user billing cycle. The double-chain design not only ensures the real-time power consumption data collection of the smart grid, but also solves the problem that the single-user power consumption cannot be measured in the traditional scheme.
