Integrated Energy System Configuration Optimization for Multi-district Heating Network Interaction

考虑多区域间热网交互的综合能源系统规划和运行优化能有效提高能源综合利用率,有助于节能减排、促进分布式能源就地消纳。在独立分区综合能源系统的基础上,在不同负荷特性区域间引入热网交互,以热网建设费用、CCHP设备投资、运行成本和碳排放税最低为综合优化目标,对多区域综合能源系统的配置和运行进行整体优化。对上海市某典型城区进行仿真优化结果表明,多区域间热网的引入有利于提高系统清洁能源利用率,合理配置设备容量,区域间用能互补特性增强,系统综合效益更佳。

The planning and operation optimization of integrated energy system considering the interaction of multi district heating network can effectively improve the comprehensive utilization ratio of energy,which helps to save energy and reduce emissions and promotes the local consumptive ability of distributed energy.Based on the integrated energy system of independent district,the heating network interaction is introduced between different load characteristic regions.Taking the minimum cost of heating network construction,the investment and operation cost of CCHP,carbon emission tax as the target of the comprehensive optimization,the overall optimization of the configuration and operation of the multi district integrated energy system is studied.Simulation analysis is conducted at a comprehensive urban area in Shanghai City.The results show that the multi district heating network interaction model is beneficial to improve the consumption of system clean energy and utilization of energy storage devices,reasonably allocate device capacity.Therefore,the complementary properties of interregional energy are enhanced,and the system's comprehensive benefits are better.
