摘要
随着具有源荷二重属性的产消者占比日益提高,如何建立适合产消者的有效交易机制,激励其能源消纳是目前亟待解决的问题。针对该问题,提出区块链技术下的产消者与运营商的集群交易模型,将区块链技术量化到产消者的用电行为上。考虑到产消者集群内各主体独立,电价制定和电量调度存在先后次序,采取Stackelberg博弈理论寻求最优交互策略,并通过区块链更新求解过程中的交互信息。仿真结果表明:通过制定内部电价,能够提升集群内的光伏自消纳水平,同时在区块链技术下聚合优化集群内资源,可以有效提高产消者的用电效益与运营商的收益。进一步,结合光伏上网电价退坡政策,再次验证了所提模型的有效性。
With the increasing proportion of prosumers possessing dual-source-load attributes,the establishment of an effective trading mechanism suitable for prosumers to incentivize energy consumption has become an urgent issue.To address this challenge,a cluster trading model based on blockchain technology for prosumers and operators is proposed,also the application of blockchain technology to prosumer electricity consumption behavior is quantified.Considering the independence of each entity within the cluster and the sequential nature of electricity price setting and quantity scheduling,Stackelberg game theory is employed to determine the optimal interaction strategy.Blockchain technology is used to update interaction information during this process.Simulation results demonstrate that establishing internal electricity pricing is able to enhance the photovoltaic self-consumption level within the cluster.Additionally,the aggregation and optimization of resources within the cluster can effectively improve the benefits of prosumers and operators by blockchain technology.Furthermore,in light of the PV on-grid tariff reduction policy,the effectiveness of the proposed model is validated.
