【摘要】：建立多时间尺度的风储发电系统协调调度模式,提出一种适用于风储联合发电系统的滚动协调调度方法。优化模型采用两阶段优化方法实现多目标决策和分层协调调度,第1阶段优化利用风电场储能系统和常规机组的协调调度最小化系统弃风电量和失负荷电量,第2阶段优化按照风电并网标准和系统调度需求在各风电场之间分配储能系统充放电任务和弃风功率。采用含3个实际风电场的IEEE 30节点系统进行仿真分析,结果表明:基于风电场滚动上报的超短期风电功率预测信息,提出的风储联合发电系统日内滚动协调调度方法能够有效减少弃风,降低系统运行成本。
[Abstract]:A multi-time scale coordinated scheduling model for wind storage power generation system is established and a rolling coordinated scheduling method for wind storage combined generation system is proposed. The optimization model adopts two-stage optimization method to realize multi-objective decision-making and hierarchical coordinated scheduling. In the first stage, the coordinated scheduling of wind farm energy storage system and conventional units is used to minimize the abandoned wind power and load loss of the system. The second stage optimizes the distribution of charge and discharge tasks and abandonment power among wind farms according to wind power grid connection standards and system scheduling requirements. The IEEE 30-bus system with three actual wind farms is used for simulation analysis. The results show that the wind power prediction information based on wind farm rolling report is very short term. The in-day rolling coordinated scheduling method for combined wind-storage generation system can effectively reduce the abandoned wind and reduce the operating cost of the system.
