Abstract:

风、光等可再生能源发电具有不确定性、间歇性的特点,如何在不同运行模式下提高可再生能源的可调度性及利用率是当前的研究热点。以含风、光、水电的虚拟电厂自身收益最大化为目标,考虑风、光、水电日内的互补性和运行特性,研究在虚拟电厂孤岛运行模式下,在给定负荷类型并考虑可中断负荷时的最大供电水平,以及并网运行模式下,考虑备用时的最优申报电量决策。所提出的2种虚拟电厂多电源协同调度随机模型采用Wasserstein距离指标对风电、光伏发电出力的连续概率分布进行最优离散化,进而通过场景缩减技术形成经典场景,从而将随机优化问题转换为确定性优化问题处理,在减少计算量和保证精度间得到适当折中。算例采用某个含风、光、水电的分布式电源示范工程的数据,分析了负荷曲线形状、风电电价、可中断负荷价格、备用价格等因素对虚拟电厂运行的影响,验证了所提模型的有效性和实用性。
