电力辅助服务市场下电采暖促进风电消纳的经济性分析
|
摘要
中国三北地区电网风电渗透率较高,同时存在高比例燃煤热电联产机组用于满足冬季巨大的采暖需求,导致其灵活调节能力极其有限,弃风问题十分突出。现有研究尚缺乏对各种类型电采暖负荷促进风电消纳的经济性评价研究,尤其是以电力辅助服务市场为背景,对不同调节特性电采暖负荷的经济性分析还鲜有报道。由此,以集中蓄热式电采暖、直热式电采暖和分布式电采暖三种典型电采暖负荷为研究对象,利用时序生产模拟方法,构建基于实时调峰辅助服务的电采暖负荷消纳弃风经济评估模型,以北方地区实际运行的电采暖项目数据为算例,对比几类典型采暖负荷消纳弃风的经济性,并分析了辅助服务价格、弃风水平和采暖负荷运行特性等关键因素对经济性的影响。计算结果显示,与传统火电机组相比,集中蓄热式电采暖和分布式电采暖的可行辅助服务价格在315～460元/MWh,具有一定的竞争力。
The wind power penetration rate of the power grid in northern China is relatively high. At the same time, a high proportion of coal-fired cogeneration units are used to meet the huge heating demand in winter, which results in limited ability of flexible adjustment and the problem of curtailed wind power. Currently, studies on economic evaluation of electric heating for wind power consumption are scarce. Especially, the economic evaluation on different types of electric heating under the background of the ancillary service market is insufficient.Thus, aiming at typical electric heating system, such as the electric boiler with heating storage, electric heat pump and distributed electric heating, this paper devotes to building economic evaluation model on the basis of ancillary service market by means of sequential production simulation. Further,the simulation calculation on three typical electric heating systems operating in northeast China is carried out. Lastly, the influence factors, such as the price, wind curtailment level and heating load characteristic are analyzed. The results show that the feasible price of ancillary service for electric boiler with heating storage and distributed electric heating varies between315 to 460 yuan/MWh. Compared with traditional thermal plants, electric heating is more competitive.
