摘　　要：提出了基于热电比拟模型的电热综合能源系统优化调度方法。首先分析了热网管网复杂的拓扑结构及传输时延造成的蓄热特性,建立了热网管网电热比拟模型;然后分析了热网主要元件运行特性,建立了与电力系统相容的热网电热比拟模型。最后以系统运行成本最小为目标函数,建立了优化调度模型。算例结果表明,在考虑热网的传输时延特性后,综合能源系统充分利用了不同能源之间的互补特性,有效降低了运行成本。An optimal dispatching method of electrothermal integrated energy system based on thermoelectric analogy model is proposed. Firstly, the thermal storage characteristics caused by the complex topological structure and transmission delay of the thermal network are analyzed with establishing the electrothermal analogy model of therinal networles. Then the operation characteristics of the main components of the heat grid are analyzed, and the electrothermal analogy model of heat network which is compatible with the power system is established. Finally, the IES optimal scheduling model is established with the minimum system operating cost as the objective function. The calculation results show that the integrated energy system makes full use of the complementary characteristics of different energy sources and effectively reduces the operating cost after considering the transmission delay characteristics of heat network.
