摘　　要：分析系统灵活性供需关系,建立灵活资源运行-规划联合优化双层配置模型。运行层引入灵活性不足率作为系统灵活性评价指标,将网损和弃风弃光量计入经济惩罚,以系统年运行成本最优为目标;规划层引入系统综合安全性指标对系统安全性进行评估,以系统年综合成本最优为目标。采用粒子群优化算法对双层配置模型进行求解。最后,利用IEEE 33节点配网系统对算例进行仿真,结果验证了所提运行-规划联合双层配置模型能有效减少网损和弃风弃光量,提高系统的经济性、安全性和灵活性。In this paper,the relationship between supply and demand of system flexibility is analyzed,and a flexible resource operation-planning joint optimization double-layer configuration model is established.The operation layer introduces the lack of flexibility rate as the evaluation index of system flexibility.This layer takes the network loss,wind power and photovoltaic curtailment to the economic penalty.And the operation layer takes the system annual operating cost as the goal.The planning layer introduces the system comprehensive safety index to the system security.This layer is aimed at optimizing the overall annual cost of the system.The double-layer configuration model is solved by particle swarm optimization algorithm.Finally,the example is simulated by IEEE 33 node distribution network system.The results show that the proposed operation-planning joint double-layer configuration model can effectively reduce the network loss and the amount of abandoned wind and light,and improve the economic,safety and flexibility of the system.
