虚拟电厂(Virtual Power Plant,VPP)通过控制技术将新能源发电、储能等资源高效整合,对实现“双碳”目标具有重大意义。为提升虚拟电厂对新能源的消纳率,构建了一种考虑配置不同类型储能系统的经济调度模型。首先,提出了包含风电、光伏、火电和储能系统的虚拟电厂结构,并建立其数学模型;其次,考虑新能源消纳过程的弃风弃光以及系统运维和碳排放成本,建立了以经济性最优为目标函数的调度模型并求解;最后,对比分析了不同容量和功率的电储能、氢储能2种储能方式对虚拟电厂调度的经济性以及风光消纳的影响。结果表明,采用氢储能可以更好的实现虚拟电厂经济性运行,并显著提高风光消纳率。
The emphasis of component system regression testing is retesting of the event interaction between updated components and other components in a system.A component system regression testing method based on a new component testing association model （CTAM） is proposed.First,the modification-affected component groups are identified by the impact analysis on CTAM,and each component in this group is assigned with an influence degree.Then,previous test cases are selected according to the influence degree,to generate the minimal regression test suite.Compared with traditional methods,CTAM is derived from the statistic on the interactive events that occurred in previous test executions,and focuses on the complicated relationship between components,which is more applicable to the component system regression testing.
