风电-抽水蓄能-供热联合优化运行——以蒙西为例
摘要：风电因为其随机性和不稳定性等特点使得风电无法实现大规模的并网而产生弃风,而抽水蓄能电站具有的良好“削峰填谷”能力,能够消纳过剩的风电。本文以供热季弃风现象尤为严重的蒙西地区为例,基于蒙西电网和呼与浩特抽水蓄能电站的实际数据,建立风电-抽水蓄能-供热联合运行的优化模型。通过研究对比结果发现在风电和抽水蓄能联合的基础上再加以蓄热电锅炉对风电进行进一步的消纳,既能提高风能的利用率减少弃风,又能解决煤炭供热污染物的排放问题,缓解化石能源资源短缺问题。
Abstract:Due to the characteristics of randomness and instability, wind power can not be connected to the grid in a large scale, and the wind curtailment is produced. Pumped storage power station has a good ability of “peak load shifting” to absorb the excess wind power. In this paper, taking the region of west Inner Mongolia where the phenomenon of wind curtailment is particularly serious during the heating season as an example, based on the actual data of power grid in region of west Inner Mongolia and pumped storage power station in Hohhot, the optimization model of wind power -pumped storage-heating combined operation is established. Through the comparative study, it is found that thermal power boilers can further consume wind power based on combining wind power and pumped storage, which enhances utilization efficiency of wind energy and reduces wind curtailment. In addition, the emission problem of coal heating pollutant is solved, and the shortage of fossil energy resources is alleviated to some extent.
