摘要(Abstract)：

随着风电和光伏发电并网规模的不断增大,传统旋转备用容量的确定方法已不能满足电力系统安全运行的要求。为此,建立了计及系统可靠性和经济性的机组组合优化模型,同时充分考虑了负荷、风电和光伏发电输出功率的预测误差以及常规机组的故障停运。采用序列运算理论对这些不确定因素进行处理,将不确定性以概率的形式综合考量,并将其引入到目标函数的计算中,能够直观体现系统运行的风险程度,从而联合优化了发电机组的出力计划和旋转备用容量。提出了采用基于离散粒子群和细菌群体趋药性的混合智能算法对模型进行求解,结合序列运算,提高了模型的求解速度和解的最优性。最后,以加入风电场和光伏电站的IEEE 10机39节点系统为算例进行仿真研究,结果验证了所提优化模型及算法的正确性和有效性。
