Research on modeling and simulation analysis of hybridelectricity-heat complementary heating system

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。

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.
