摘要：

在考虑电热能源互联基础上，提出了计及多时段尺度与地域分层的电热多能互补系统经济调度策略，该策略从单时段和多时段角度出发，综合考虑局域级和区域级的能量平衡关系，以实现电热多能互补系统经济调度为目标。首先，在采集局域级各类能源资源数据与信息的基础上建立母线式电、热能平衡模型；然后，提出区域级能量平衡公共母线式模型，并采用小容量机组等效思想来等效聚合同类型机组；其次，建立典型局域级电热互联能源系统模型；最后，对电热多能互补系统经济调度求解，并输出经济调度结果信息。对电热多能互补系统的经济调度的有效性与合理性通过仿真算例已经得到验证，为区域级电热多能互补系统多能互补利用、资源协调配合、经济高效运行及分析提供参考与理论指导。

Abstract:

To complete the coupling and interconnection of electric and heating sources，an economic dispatch strategy for electric-heating coupled multi-energy complementary systems considering multi-period scales and regional stratification is provided. Analyzing from the perspectives of single period and multi-period，this strategy comprehensively considers the energy balance relationship at local level and regional level to achieve the economic dispatch of a multi-energy complementary system. Firstly，bus electric balance model and bus heating balance model are established based on the collected data and information of local-level energy resources. Secondly，a common bus energy balance model at regional level is proposed，in which the equivalent idea is adopted to aggregate the units of the same type. Then， a typical electric-heating coupled energy system model at local level is established. Finally，the economic scheduling results are obtained from the electric-heating coupled system dispatch strategy implementation. The effectiveness and rationality of the economic dispatch of the electric-heating coupled multi-energy complementary system have been verified through simulation examples，providing reference and theoretical guidance for multi-energy complementary utilization，resource coordination，economic and efficient operation of the multi-energy complementary systems at regional level.

Key words: energy balance, electric-heating coupled multi-energy complementary system, multi-energy flow, integrated energy system, multi-period, electric-heating interconnection, economic dispatch
