摘要(Abstract)：

大量以风电和光伏为代表的间歇性可再生能源的接入对系统可控电源的灵活运行能力提出了更高的要求,为实现含高比例可再生能源的电力系统可靠性运行,亟需建立一套考虑风光出力特性的系统灵活性定量评估体系。考虑新能源发电的多时间尺度波动特性,提出一种基于形态学分解的电力系统灵活性评估指标及其计算方法。首先通过数学形态学算法分解净负荷曲线,得到多时间尺度分量曲线,并根据不同频段的波动分量得出对应的向上、向下灵活性需求;然后,建立系统内不同类型可控机组在不同波动时间尺度下的灵活性调节能力模型;通过对同一时间尺度下的灵活性资源与需求的匹配分析,计算各时间尺度的向上、向下灵活性不足概率、灵活性不足期望和灵活性裕度期望指标;加权形成系统灵活性评估综合指标。基于南方某电网实际数据进行系统灵活性指标评估,验证所提指标和评估方法的有效性。
