中文摘要:

      供电商向综合能源供应商的转型发展在能源互联网大背景下顺应而出。提出一种分层综合能源服务商低碳运行模式，上层综合能源服务商保证源端供能设备低碳运行，下层综合能源服务商保证终端耗能设备低碳高效运行。基于综合能源系统低碳指标，优化终端用户节点混合供能运行模式，并通过终端用户侧碳减排率以及全天综合能源利用率对不同低碳供能模式进行评估分析。通过优化仿真可得出，电蓄热锅炉的加入对于混合供热节点处的碳减排效果显著，而在混合供热节点处燃气锅炉的辅助供热对综合能源利用率提升具有明显成效。

英文摘要:

      The transition from electricity suppliers to integrated energy suppliers is coming out in the background of the energy Internet. It was proposed that a sort of low-carbon operation mode for hierarchical integrated energy service provider which was composed of 2 stages. The first-class service provider dealt with low-carbon unit and grid scheduling and produced low-carbon and comprehensive energy consumption indexand delivered them to the sec-ond-class service provider. Based on the low carbon index of intergrated energy system, the hybrid energy supply mode at the end-user node was optimized. The analysis of low-carbon operation strategy was carried through by the rate of carbon reduction and integrated energy utilization of terminal users. Through the optimized simulation, it could be concluded that the addition of electric heat storage boilermakes for carbon emission reduction, while the gas boiler makes for improving the integrated energy utilization rate.
