摘要(Abstract):
大规模并网风电的出力不确定性及反调峰特性给电力系统运行,尤其是机组组合的安全可靠性、经济性带来了严峻的挑战。合理构建风电出力不确定性模型,并将新的优化方法,如随机优化、鲁棒优化等应用到机组组合中已成为当前的研究热点。首先对风电场潜在调节能力进行了探讨,提出了一种新的风电调度模式及相应的机组组合模型。风电场在新的调度模式下将转变为一个"灵活"的参与者,而机组组合模型同时计及了风电场出力的不确定性。然后,以修订后的IEEE 39节点系统为基本算例对所提方法进行了仿真分析,结果表明所提出的方法可有效地提高电力系统运行的整体性能。此外,所提方法还可用于评估系统对风电的接纳能力。
