摘要(Abstract)：
小水电在拦蓄洪水、调节径流、改善能源结构、促进生态环境保护和当地农民增收、基础设施改善等方面发挥了巨大作用。基于某市电网的实际情况阐述了峰谷时段调整的必要性，分析了峰谷时段调整情况和浙江省水电上网电价政策。基于峰谷时段调整前后某市电网的网供关口、小水电的电厂出力等实测数据的复盘，分析了峰谷时段调整对小水电发电行为的影响。结果表明，峰谷时段调整在一定程度上改变了小水电的发电行为，有效缓解了该市网供关口负荷昼夜“峰谷倒置”的情况。
Small hydropower plays a pivotal role in flood retention and storage,runoff regulation,energy mix improvement,ecological environment protection acceleration,income increase of local farmers,and infrastructure enhancement. This paper expounds the necessity of the peak and valley time division adjustment based on the specific condition of a municipal power grid. Then the peak-valley time division adjustment situation and the FIT(feed-in tariff)of the small hydropower are provided. Finally,based on the review of measured data,including gateway electricity consumption and the output of small hydropower,the influence of the peak and valley time division adjustment on small hydropower is analyzed. The results show that the adjustment of peak and valley time can change the power generation behavior of small hydropower and ease the condition of peak-valley inversion in the gateway between day and night.
