摘要: 为进一步提升终端的调峰能力,有效削弱风电出力的不确定性对风电消纳的影响,提出了一种考虑终端“储热”差异性的风电消纳最优化技术。首先,基于用户电负荷、热负荷、采暖室温等数据分析了终端热负荷的差异性;其次,基于扰动单价、扰动时长、采暖温度等变量分析了终端“储热”的差异性;最后,利用场景分析法构造了不同的终端热负荷空间分布场景,并基于所提出的技术进行了仿真计算。将调控前后的效果进行比较,主要结论如下:(1)近端型热负荷空间分布下风电消纳量最大提高7.23%;(2)不同种类用户室温在各自接受的范围内波动,A类用户波动幅度最大为6 ℃,C类用户采暖室温最大为30 ℃;(3)风电消纳与热电厂收益的提高表明了文章所提策略的技术可行性与经济可行性。

Abstract:  In order to further improve the peak-shaving ability of the terminal and promote the wind power consumption, a technology for improving the peak-shaving capacity and optimizing the wind power consumption considering the difference of the terminal “storage heat” is proposed. Firstly, according to the users electric load, heat load, heating temperature and other data, the difference of terminal heat load is analyzed. Secondly, the difference of terminal “heat storage” is analyzed on the basis of variables such as disturbance unit price, disturbance duration and heating temperature. Finally, using the scene analysis, this paper constructs different terminal thermal load spatial distribution scenarios and performs simulation calculation based on the proposed technology. The main results are as follows: 1) The wind power consumption of the near-end heat load is increased by 7.23%; 2) Load fluctuation of different types of users are within the range of their respective acceptance, the maximum fluctuation of users of class A is 6 °C, and the temperature of c users of class C is 30 °C. 3) The increase of wind power consumption and thermal power plant revenue show the technical and economic feasibility of the proposed strategy.
