1、含风储联合单元的电力系统两阶段日前调度模型张学军1,王振2(1.山西大学动力工程系，太原030013；2.山西大学电力工程系，太原030013)摘要:针对电力市场环境下含风储联合单元的电力系统日前调度问题，建立了两阶段调度优化模型。第一阶段基于描述风功率不确定性的概率场景集，考虑弃风和投标偏差惩罚，以风储联合单元的期望收益最大为目标，优化单元的日前投标量；第二阶段考虑风储联合单元出力偏差惩罚、环境成本和网络约束等因素，以系统综合运行成本最小为目标，进行日前机组组合优化。此外，还提出了一种日前出清偏差惩罚机制。IEEE-30节点6机系统的
2、仿真实验表明与传统调度模型相比，该模型具有风储调度出力偏差小，系统综合运行成本低，环保效益明显的特点。关键词：风储联合单元;调度优化;电力市场;偏差惩罚;网络约束中图分类号：TM933文献标识码：B文章编号：Thetwo-stageday-aheadoperationmodelofthepowersystemwithwind-storagecombinedunitZhangXuejun1,WangZhen2(1.DepartmentofPowerEngineering,ShanxiUniversity,Taiyuan030013,Chi
