【摘要】 随着"碳达峰,碳中和"目标的提出,清洁能源在电网中的比重呈增加趋势。虽然目前新能源建装机规模明显提升,但由于调峰稳定性有所欠缺,目前依然主要是水电参与电网调峰。对于有不完全年调节能力及以上的水库而言,汛末期及蓄水期尽量抬升库水位,一方面可提高水头效益,另一方面可应对调峰、平衡新能源负荷的需求,但高水位运行会存在一定防洪风险。为了分析中期(月度、季度或汛期)调度过程不同水位控制策略对防洪和蓄水的影响,建立了中期调度模型,基于不同频率设计洪水以及历史来水资料,计算了调度期不同初、末水位组合下水库的弃水风险和蓄水可能性。结合实例进行了水位控制分析,对水库调度策略的制定提供了依据。更多还原

【Abstract】 Following the goal of emission peak & carbon neutrality,the proportion of clean energy in power gird is increasing.Although the installed capacity of clean energy increases obviously,nowadays hydropower is primarily involved in peak regulation.For incomplete annual storage reservoirs,raising reservoir water level as far as possible may improve water head benefit and additionally is able to meet the need of peak regulation and balancing the new energy load,while is at risk of flood.In order to analyze the effect of different water level combination strategies to flood control and impoundment,a mid-term(monthly,quarterly or flood season) schedule model is established,and both risk of abandonment and possibility of impoundment in scheduling are calculated in different water level combination strategies.This way of analysis is applied to some reservoir and provides basis for generating reservoir operation strategy.更多还原
