北京市电供暖经济可行性和可持续发展研究

摘要
电供暖项目有利于改善大气环境并促进新能源电力消纳,是电力需求侧管理的重要对象。目前电供暖项目经济性较差,大规模建设容易形成政府和电网公司的额外负担。为探讨实现我国电供暖可持续发展的可行方案,构建了临界电价模型,并基于调研获取的边界条件数据,计算了北京市3种类型集中式电供暖项目可承受的最高电价。结合冀北地区风电项目输配电价计算和可承受最低电价分析,讨论了北京市集中式电供暖项目的经济可行性,并分析电供暖项目参与电力交易存在的其他障碍,最终提出政策建议。研究结果表明,在无补贴、少补贴条件下部分电供暖项目可通过电力交易实现盈利,大幅减少财政补贴和电网公司负担,从而实现电供暖的可持续发展。
Electric heating projects are conducive to improving atmospheric environment and promoting new energy power consumption,which are important objects of power demand side management.At present,the economy of electric heating projects is poor,and large-scale construction causes additional burdens on the government and power grid companies.In order to explore the feasible scheme for realizing the sustainable development of electric heating,the critical tariff model is constructed.Based on boundary condition data obtained by investigation,maximum affordable tariff of three kinds of electric heating projects is calculated.Combined with calculation of the transmission and distribution price and analysis of the lowest affordable price of wind power projects in northern Hebei province,the economic feasibility of centralized electric heating projects in Beijing is discussed.The other obstacles of electric heating projects participating in power transactions is analyzed,and suggestions of policies are put forward at last.The results of the study show that under the condition of no or less subsidy,part of electric heating projects can generate profits through electricity transactions,financial subsidies and burdens of power grid corporations can be reduced significantly,thus realizing the sustainable development of electric heating.
