The profitability of electric heating projects in Northern China is poor. A kind of combined market-oriented trading strategy to improve the economy of electric heating projects is put forward. The price game model for direct power purchase, compensation model for carbon emission reduction benefits and load aggregation revenue model are constructed, and the optimal proportion of clean energy and conventional energy consumed under the condition of ensuring heating reliability is analyzed. An electric heating project was analyzed as an example, the results showed that in the direct power purchase transaction, the power price is 0.2125 RMB/kWh, which is 0.0591 RMB/kWh lower than the catalogue tariff. Revenue from carbon trading and auxiliary service transaction is 469,913.87 RMB and 289,218.09 RMB, respectively, which is equivalent to reducing electricity cost of 0.0253 RMB/kWh and 0.0156 RMB/kWh, respectively. The ultimate power cost is 0.1716RMB/kWh, which is 0.1 RMB/kWh lower than the current catalogue tariff. Besides, the more clean energy an electric heating project consumes, the better its economy will be, and in this example, the best proportion of clean energy and conventional energy is 80% and 20%. The research results could help to promote the sustainable development of clean heating in northern China.
中国北方地区电供暖项目盈利状况不佳。针对这一问题，提出了一种市场化的综合交易策略，以提高电供暖项目的经济性。构建了直接购电的价格博弈模型、碳减排收益补偿模型和负荷聚合收益模型，分析了在保证供暖可靠性的条件下，清洁能源和常规能源的最优消费比例。以一个电供暖项目为例进行分析，结果表明：在直接购电交易中，电价为 0.2125 元/kWh，比目录电价低 0.0591 元/kWh；碳交易和辅助服务交易的收入分别为 469913.87 元和 289218.09 元，相当于降低电供暖成本 0.0253 元和 0.0156 元/kWh；最终的电力成本为 0.1716 元/kWh，比现行目录电价低 0.1 元/kWh。此外，电供暖项目消耗的清洁能源越多，其经济性越好，在本例中，清洁能源和常规能源的最佳比例为 80%和 20%。研究结果有助于促进中国北方地区清洁供暖的可持续发展。
