摘要(Abstract)：

近年来,我国西南水电主导的电网中风光占比大幅提升,对水电灵活性提出了更高的要求。如何量化大规模风光并网后的水电灵活性,是促进水风光协同发展和大规模消纳的关键因素。为有效量化及提升水电灵活性,在供需双侧开展了量化方法研究。首先,在灵活性供给侧,结合水电站历史运行特性,提出了一种考虑可获得性的水电灵活性供给能力量化方法,定义了水电灵活性变化特征区;其次,在灵活性需求侧,基于分位点回归理论,提出了响应新能源预测误差的数据驱动水电灵活性需求量化方法;最后,通过灵活性供需关系约束,将上述量化方法耦入短期调度模型,来验证所提方法的有效性及合理性。以云南电网为工程背景,仿真结果对比表明,该方法可有效认知水电灵活性供需关系,提升水电灵活性。与其他量化方法对比表明,该水电灵活性量化方法,可兼顾多方面综合要求,可获得性更高。
