Abstract: In order to improve the efficiency of user transactions in virtual power plants and the security of operation and dispatching, in view of the high cost, high risk, and low efficiency in the operation and dispatching of traditional virtual power plants, an energy blockchain network based on multiple power users is proposed. A mode of virtual power plant operation and dispatching is given. The power transaction consensus algorithm is used to intelligently match multiple users with different needs in the virtual power plant to improve the reliability and economy of user transactions. The energy blockchain network is introduced and an improved virtual power plant operation scheduling model is proposed, which not only ensures the information storage security, but also makes operation and dispatching more stable and transparent. The case analysis shows that the model proposed in this paper can effectively improve the security and efficiency of transaction and dispatching in virtual power plants, and can provide reference for energy transaction in virtual power plants.

摘要： 为提高虚拟电厂中用户交易的效率及其运行调度的安全性，针对传统虚拟电厂运行调度中高成本、高风险、低效率的问题，基于多元用电主体概念，提出了能源区块链网络中的虚拟电厂运行与调度模式。为提高用户交易的可靠性和经济性，采用电力交易共识算法对虚拟电厂中不同需求的多元用户进行智能匹配；引入能源区块链网络，提出改进的虚拟电厂运行调度模型，不仅保证了信息存储的安全性，还使得运行调度更加稳定透明。案例分析表明，本文提出的模型能够有效提高虚拟电厂中交易与调度的安全性和效率，可以为虚拟电厂中的能源交易提供参考。
