摘　　要：为提升电力需求响应控制效果,设计基于区块链技术的用户侧电力需求响应控制系统。利用网关节点采集负荷数据,将数据传输至能源区块链中。将区块链技术应用到数据层进行分布式信息的获取和保存。利用基于数据分割的多级加密机制,处理负荷数据。采用需求响应聚合商模块读取能源区块链内存储的数据,制定电力需求响应合同内的响应起止时间与响应负荷等数据。利用网关读取电力需求响应合同内的数据,创新性地按照智能家电动态优先级执行控制算法,制定用户侧电力需求响应控制方案,以实时控制设备运行状态,从而完成用户侧电力需求响应控制。试验结果表明:该系统加密数据时的吞吐量稳定在0.61 Gbit/s。该系统可有效控制用户侧电力需求响应,降低用户的负荷功率。To improve the effect of power demand response control,a user side power demand response control system based on blockchain technology is designed.The gateway node is utilized to collect load data and transmit the data into the energy blockchain.Blockchain technology is applied to the data layer for distributed information acquisition and preservation.The load data is processed by using a multi-level encryption mechanism based on data segmentation.The demand response aggregator module is used to read the data stored in the energy blockchain and formulate the response start and stop times and response loads and other data in the power demand response contract.Using the gateway to read the data in the power demand response contract,the control algorithm in accordance with the dynamic prioritization of smart home appliances is innovatively executed,the user side power demand response control scheme is formulated,so as to real-time control the operating state of the equipment,and complete the user side power demand response control.The test results show that the throughput of the system when encrypting data is stabilized at 0.61 bit/s.The system can effectively control the user side power demand response and reduce the user's load power.
