In this paper 关键词：机组组合；风电；模糊机会约束；不确定理论；混 the unit commitment considering fuzzy confidence level of 合整数线性规划 wind power generation is researched. During the modeling, the fuzziness of wind power output is incarnated as the fuzziness 0 引言 of prediction error, and based on credibility theory the 风力发电是我国能源战略的重要方向，大规模 credibility distribution function of prediction error of wind 风电利用问题受到学术界和工程界的广泛关注[1] 。 power generation is derived, and on this basis the fuzzy chance constraints for spinning reserve are e
