混合式电热互补供暖系统建模与仿真分析研究
摘要：建立了热力站处配置电供暖设备的新型混合式电热互补供暖系统，并对系统进行建模仿真和性能分析。研究表明，相比于集中式电热互补供暖系统，采用配置热泵和蓄热装置的混合式电热互补供暖系统的环境、经济和节能效益指标优化比分别为1.91%、2.41%、2.90%。随着电替代供暖负荷比例的增加，混合式电热互补供暖系统的各个性能评价指标优化比逐渐提高。通过电供暖增加了供热系统的可再生能源消纳，并有效降低了热网损耗，系统性能得到较大提升。

Research on modeling and simulation analysis of hybrid electricity-heat complementary heating system
Abstract: This paper presents a new hybrid electricity-heat complementary heating system configured with electric heating equipment at the heat station, and the system is modeled, simulated, and analysed for performance. The results show that compared with the centralized electricity-heat complementary heating system, the optimization ratios of the hybrid electricity-heat complementary heating system with heat pump and thermal storage device are 1.91%, 2.41%, and 2.90% in environmental, economic, and energy efficiency indexes, respectively. With the proportion of the electric replacement heating load increases, the optimization ratios of each performance evaluation index of the hybrid electricity-heat complementary heating system gradually improve. Through electric heating, the renewable energy consumption of the heating system is increased, the loss of heat network is effectively reduced, and the system performance is greatly improved.
Keywords: central heating system; hybrid electricity-heat complementary heating system; electric heating; electricity replacement; energy complementation; simulation;
