摘要
选取济南、大连、沈阳3个城市,探讨供暖电气化对社会用能的影响。假定所有供暖热负荷均由热泵系统满足,根据各地气象参数,采用面积指标法得出供暖热负荷,根据热泵系统COP计算供暖耗电量,与全社会耗电量、居民耗电量、工业耗电量进行对比。借助Dymola仿真模型,计算各城市当前风力、光伏装机容量下可再生能源发电量,分析其与供暖耗电量关系。给出未来中国建筑供暖的发展建议。结果表明:现阶段,北方地区实行供暖电气化将给现有电网带来强烈冲击,3个城市供暖期光伏发电几乎可以忽略,风力发电受间歇性影响严重。借鉴欧盟能源转型路径,未来需保持终端用能与设备多样化发展,以保证能源系统的弹性。
Jinan,Dalian and Shenyang are selected to discuss the impact of heating electrification on social energy consumption.Assuming that all heating loads are met by the heat pump system,the area index method is used to obtain the heating heat load according to the meteorological parameters of various regions.The heating power consumption is calculated according to the COP of the heat pump system,and compared with the power consumption of the whole society,residents and industry.With the help of Dymola simulation model,the renewable energy power generation under the current wind and photovoltaic installed capacity of each city is calculated,and the relationship between the renewable energy power generation and heating power consumption is analyzed.Suggestions for the future development of building heating in China are given.The results show that at present,the implementation of heating electrification in the northern regions will have a strong impact on the existing power grid.Photovoltaic power generation during the heating period in three cities can be almost ignored,and wind power generation is seriously affected intermittently.Drawing on the EU energy transformation path,it is necessary to maintain the diversified development of terminal energy use and equipment in the future to ensure the flexibility of the energy system.
