摘要(Abstract)：

在含可再生能源的电力系统中,发电容量的灵活性会影响系统的可靠性和可再生能源的消纳,传统的发电容量充裕度指标无法全面反映含可再生能源电力系统的发电容量可靠性。为此,首先提出了电力系统向上/下发电容量不足指标,用于综合描述电力系统的发电容量充裕度和灵活性。其次,采用随机生产模拟技术,给出了向上/下发电容量不足指标的随机评估方法,其中考虑了发电机组的随机强迫停运、最大/小技术出力限制以及不同出力状态下的向上/下爬坡速度,并可适用任意时间尺度下的时序负荷,从而反映了发电机组受负荷需求影响导致的爬坡容量不确定性和由其本身强迫停运导致的不确定性。最后,通过算例分析验证了所提指标和方法的有效性,并定量研究了风电接入比例、时间尺度等因素对向上/下发电容量不足指标的影响。
