“双碳”背景下能源互联网数字孪生系统的设计及应用

Design and application of energy internet digital twin system under the background of"dual carbon"

为提高能源供需平衡、降低能源消耗,提出“双碳”背景下能源互联网数字孪生系统设计。通过物理感知层、传输交互层、数据共享层、应用服务层以及虚拟空间和安全防护构成能源互联网数字孪生系统的整体框架。从二氧化碳排放量和容量投资成本这2个目标出发,构建目标函数,在相关约束条件的基础上,采用和声搜索算法求解目标函数,实现能源互联网的规划,完成能源互联网数字孪生系统的设计。实验结果表明,所设计系统的燃气、水和电消耗量均较低,且蓄电池容量高、能源供需平衡。

In order to improve the balance of energy supply and demand and reduce energy consumption,the design of digital twin system of energy Internet under the background of"double carbon"is proposed.The physical perception layer,transmission interaction layer,data sharing layer,application service layer,virtual space and security protection constitute the overall framework of the digital twin system of energy Internet.Starting from the two objectives of carbon dioxide emissions and capacity investment cost,the objective function is constructed.Based on relevant constraints,the harmonic search algorithm is applied to solve the objective function,so as to realize the planning of the energy Internet and complete the design of the digital twin system of the energy Internet.The experimental results show that the gas consumption,water consumption and electricity consumption of the designed system are low,and the storage battery capacity is high,and the energy supply and demand are balanced.
