摘要/Abstract

摘要： 为建立一种新型的电力系统灵活性评估方法,实现高比例可再生能源电网的消纳及调峰灵活性的综合量化分析,在电力系统灵活性理论的基础上,将可再生能源的消纳情况纳入灵活性评估的范畴,提出以系统功率供需平衡为核心的高比例可再生能源电网消纳及调峰灵活性理论和分析方法。结合不同的可再生能源出力曲线,分析可再生能源接入对系统调峰灵活性的影响机理;基于系统总体的功率过剩和灵活性资源实时的爬坡能力不足情况,从可再生能源消纳灵活性和系统调峰灵活性两个方面构建评估指标;基于某含高比例可再生能源区域电网的实际数据设置算例,对所评估系统的灵活性盈余以及灵活性不足情况进行定量计算,并以可再生能源和储能机组装机量为变量进行工况区分,分析不同影响因素下系统灵活性的变化。算例表明,随可再生能源机组容量的增大,系统的调峰和消纳灵活性均有所降低,但随着储能机组接入容量的增加,高比例可再生能源造成的功率波动与消纳问题得以有效解决,系统调峰及消纳灵活性均有所提高,验证了本研究所提出的高比例可再生能源电网消纳及调峰灵活性综合评估体系的有效性。
