摘　　要：应对高渗透率的风电光伏不确定性要求充分发挥各种资源的灵活性,因此从传统的柔性资源,如具有快速上升/下降旋转储备的火电机组和输电线路传输切换出发,提出了一种具有多个柔性资源的安全约束机组组合模型。该模型将需求响应、输电线路传输切换及公共储能集成在一个集成方案中,通过协调优化源网荷储侧的这些柔性资源,以应对风电光伏出力和系统元件偶发故障的不确定性。针对这一大而复杂的计算问题,提出了一种新的加速分解技术,旨在提高模型求解效率,减少迭代次数和CPU计算时间。Achieving full potentialof various kinds of power sources is of significance for coping with the uncertainty brought by high-proportion integration of wind and photovoltaic generations.In view of this,the present work made an attempt at establishing a multi-flexible-source-entailed security-constrained unit combination model based on the conventional flexible sources,such as thermal power units with rapid rise/fall spinning reserve,and transmission line switching.The model integrates demand response,transmission line switching,and public energy storage into one combined scheme.It coordinates and optimizes these flexible sources on the sides of source,grid,load,or storage,thereby facilitates coping with the uncertainties resulted from wind and photovoltaic generations and accidental faults of system components.Aiming at this large and complex computing problem,a new accelerated decomposition technology was proposed to improve the efficiency of model solving and reduce the number of iterations and CPU computing time.
