摘要(Abstract)：

以系统的经济成本和CO2排放量最小为优化目标,兼顾发电侧与需求侧柔性负荷的双侧协调配合,建立了考虑柔性负荷的多目标安全约束机组组合优化模型。针对传统法线边界交叉(normal boundary intersection,NBI)法求解上述模型时出现的混合整数二次规划和混合整数二次约束问题,提出了引入分段线性化策略的NBI法,在保证计算精度的同时,大大提高了求解效率。对一个10机24时段算例进行了仿真计算,一方面证明了所提算法的有效性,另一方面表明柔性负荷调度有利于提高系统的经济性,降低系统的碳排放量;同时,需求侧柔性负荷的参与对减小负荷峰谷差、缓解负荷高峰期用电压力具有重要作用,并促进了风电的进一步消纳,有助于清洁能源的利用。

关键词(KeyWords)： 柔性负荷;多目标;安全约束机组组合;分段线性化;法线边界交叉法
