摘要: 中国三北地区风资源丰富,但受制于热电联产机组以热定电的出力特性,在供热季节弃风严重。集中供热系统覆盖的范围大,管道容积巨大,储热能力与热惯性强,如能对集中供热系统加以合理调节,可对改善电力系统调峰、促进风电消纳起到显著效果。为了改变电网调峰能力不足的现状,中国各地陆续开展调峰辅助服务市场,以激励火电机组改造,提高灵活性,挖掘出力下限。在此背景下,针对考虑调峰辅助服务的热电联合调度方法开展研究,对供热系统进行了建模以刻画其动态特性,并在目标函数中计及了辅助服务的调用顺序。在省网规模的系统进行了仿真测试,验证了所提出模型的合理性,并计算了其在促进风电消纳方面的经济效益。

Abstract: China's northern regions are rich in wind resources, but the wind curtailment becomes a critical problem during the heating season due to the output characteristics of combined heat and power units. The central heating system covers a large area, and has a huge pipeline volume and a strong heat storage capacity and thermal inertia. If the central heating system can be dispatched reasonably, the peak regulation of the power system can be significantly improved, and the wind power consumption can be promoted. In order to improve the peak regulation capacity of power grids, the peaking ancillary service market has been launched in various areas in China to stimulate renovation and flexibility of the thermal power units and to expand their output regions. This paper makes a study of the coordinated dispatch method of heat and power systems considering peaking ancillary services, and constructs heating system models to characterize their dynamic characteristics, in which the ancillary services are considered in the objective function. Simulation tests are conducted through a provincial-level system, which demonstrate the rationality of the proposed model, The economic benefits of the model are calculated in promoting wind power consumption.

Key words: peaking ancillary services, combined heat and power dispatch, wind power utilization, heating system, combined heat and power unit
