基于区块链的可靠电力数据调度方案

Reliable Power Data Scheduling Scheme Based on Blockchain

智能物联网的高速发展使得电网中的电力信息资源能够实现高效聚合。区块链技术的不可篡改性、透明性、高可用性,使得共享信息变得更加安全和高效。随着能源电力市场的开放,负荷调控、优化配置等需求日益迫切。在信息收集阶段可以通过电网中的智能设备收集电力数据,但在电力数据调度阶段存在信息共享壁垒、虚假信息威胁等问题,严重影响调度效益。为此,设计一种基于区块链的可靠电力数据调度方案。该方案利用区块链实现调度信息共享,链下设计适用于电力调度场景的智能终端设备准入机制,将调度风险规避在链下;设计基于数据可靠性评估的电力数据发布方法及基于效益理论的多策略调度模型,保障上链数据的可靠性,实现数据调度风险的可控;设计基于动静态评价结合的信任更新计算方法,实现用户调度行为量化上链。通过对调度成功率、系统总收益等指标进行仿真实验,验证了该方案的有效性。

The rapid development of the intelligent Internet of Things(IoT)has enabled efficient aggregation of electrical information resources in the power grid.The immutability,transparency,and high availability of blockchain technology enhance the security and efficiency of shared information.With the opening of the energy and electricity market,the demand for power resource integration,load regulation,and optimized allocation has become increasingly urgent.During the information gathering stage,electricity data can be collected through intelligent devices in the power grid.However,in the stage of electricity data dispatch,there are barriers to information sharing and threats of false information,which seriously affect dispatch efficiency.In this paper,a reliable power data dispatch scheme based on blockchain is proposed.The scheme utilizes blockchain to achieve information sharing in dispatching,and off-chain design for intelligent terminal device access mechanisms applicable to electricity dispatch scenarios.It designs a power data publication method based on data reliability assessment and a multi-strategy dispatch model based on utility theory to ensure the reliability of on-chain data and achieve controllable data dispatch risks.Furthermore,it designs a trust update calculation method based on dynamic and static evaluation combination to quantify user dispatching behaviors on the blockchain.The effectiveness of the proposed scheme is validated through simulation experiments on dispatch success rate,total system revenue,and other indicators.
