不确定环境下含云计算数据中心的电网韧性增强调度 = Resilience-enhanced scheduling of power system with cloud computing data centers under uncertainty
为解决飓风来临前路径不确定时输电线路随机故障等带来的难题,提出了适用于含云计算 数据中心的电网韧性增强日前调度策略,并将其构建为两阶段风险规避的分布鲁棒优化问题。以 飓风对输电线路的时空影响为出发点,采用蒙特卡洛模拟获得飓风路径不确定时线路的离散故障 集合,并构建基于L1 距离度量的分布鲁棒模糊集合。然后,在日前调度中,对机组和数据中心进行优化以平衡经济性和电网韧性,并采用追索问题量化其对日间调度的影响,形成两阶段优化问题。随后,对优化问题进行确定性转换与解耦求解。最后,以含4 个数据中心的IEEE-RTS 系统为测试算例,验证了所提韧性增强策略应对模糊不确定性的有效性。 To man...
