针对多能源系统中能源供给设备、电/热/气负荷等全方位数据处理与计算需求的增加,使得电/热/气多能源系统愈加难以实现高效、精准运行的问题,文章提出了一种基于数字孪生技术的电/热/气多能源系统优化运行策略。首先,通过分析数字孪生技术所具备的优势,提出基于电/热/气多能源系统的数字孪生控制框架,并建立“物理实体层-网络通讯层-运行服务层”三者协同的多能源系统优化运行机制;其次,通过分析系统内各能源供给设备运行特性,建立电/热/气系统能源供给设备物理感知模型;再次,建立考虑运行成本、环境成本最优的电/热/气多能源系统优化运行模型,并对优化模型进行求解;最后,搭建电/热/气多能源系统数字孪生仿真模型进行分析。研究结果表明,文章提出的优化策略能够有效提高电/热/气多能源系统数据信息处理能力,并降低系统的运行成本。
In view of the problem that it is increasingly difficult to achieve efficient and accurate operation of electricity/heat/gas multi-energy systems due to the increased demand for comprehensive data processing and calculation of energy supply equipment and electricity/heat/gas loads,a coordinated and optimized operation strategy for electricity/heat/gas multi-energy systems based on digital twin technology is proposed in this paper.Firstly,by analyzing the advantages of digital twin technology,a digital twin control model of the electricity/heat/gas multi-energy system is proposed,and a multi-energy system optimized operation mechanism of"physical entity layer-network communication layer-operation service layer"is established.Secondly,by analyzing the operating characteristics of each energy supply equipment in the system,the energy supply equipment physical perception model of the electricity/heat/gas multi-energy system is established.Then,an optimal operation model of the electricity/heat/gas multi-energy system is established with the optimal system operation cost and environmental cost,and the optimization model is solved.Finally,a digital twin simulation model of the electricity/heat/gas multi-energy system is established for analysis.The results show that the optimization strategy proposed in this paper can effectively improve the data and information processing capability of the electricity/heat/gas multi-energy system.It also can reduce the operation cost of the system.
