摘要：

冬季供暖期燃气热电机组采用“以热定电”运行方式极大地限制了燃气机组的调峰能力，热电解耦是解决这一问题的有效途径。为促进燃气热电厂开展热电解耦的积极性，在华北电力调峰辅助服务市场的基础上提出了北京地区燃气机组热电解耦补偿机制，从而提高燃气机组热电解耦动力，并以机组加装电锅炉辅助供热为例进行算例分析。根据所提热电解耦补偿机制，在燃气机组加装电锅炉热电解耦供热改造情况下，燃气机组供暖季调峰运行可获得补偿费用12 192.85万元。机组供暖季热电解耦压减电量及新增调节容量奖励电量与清洁能源替代发电可获得增量收益约4 348.3万元，一定程度上补偿了机组因深度调峰而减少的发电收益，能够缩短燃气机组热电解耦成本回收期限，提高燃机热电解耦改造的积极性。

Abstract:

Thermoelectric decoupling is an effective way to solve this problem. The operation mode of the gas-fired thermoelectric unit in winter heating period greatly limits the peak regulating capacity of the gas-fired unit. In order to promote the enthusiasm of gas thermal power plant to carry out thermoelectric decoupling, a thermoelectric decoupling compensation mechanism for gas units in Beijing is proposed based on the peak regulating auxiliary service market of North China Electric Power plant, so as to improve the thermoelectric decoupling power of gas units. A case study is carried out with auxiliary heating of electric boiler installed in the unit. According to the proposed thermoelectric decoupling compensation mechanism, when the gas-fired unit is equipped with electric boiler thermoelectric decoupling heating transformation, the compensation cost of the gas-fired unit can be 121.928 5 million RMB during peak operation in the heating season. In the heating season of the unit, incremental income of about 434.83 million RMB can be obtained by thermoelectric decoupling reduced quantity and newly adjusted capacity incentive quantity and clean energy replacement generation, which compensates the generation income reduced by the unit due to deep peak regulation to some extent, can shorten the cost recovery period of the gas unit thermoelectric decoupling, and improve the enthusiasm of gas turbine thermoelectric decoupling transformation.
