摘　　要：在实施可中断负荷项目时,因用户消费行为、客观条件等因素,造成了用户响应程度存在着不确定性,且其不确定性的大小与激励程度有直接联系,这种不确定性的大小最终影响整个系统的可靠性供电指标。构建考虑不确定性的可中断负荷响应模型,利用可中断负荷与备用的协调优化模型确定不同可靠性供电指标要求下的系统最优备用容量与不确定性可中断负荷配置关系。IEEE-RBT 6节点算例结果表明,大量用户响应具有明显的集群效应,有助于弥补单个用户响应的不确定性,并且在不同的可靠性要求下,优化模型中发电机备用与可中断负荷备用的配置具有不同的特点,体现了经济性和可靠性的协调,从而能够更合理地优化资源配置。The response uncertainty of interruptible load is caused by different factors,such as user consumption behaviour,objective conditions,etc.,and its degree is directly related to the incentive extent, which will eventually affect the reliability index of overall system power-supply. An interruptible load model with response uncertainty is built and the optimization model of coordination between interruptible load and reserve is adopted to determine the configuration relationship between the optimal system reserve capacity and the interruptible load with response uncertainty under different reliability indexes. The results of case study for IEEE-RBT 6-bus system show that,the significant crowding effect of massive users may compensate the response uncertainty of single user;the different configuration characteristics of generator reserve and interruptible load in the optimization model under different reliability indexes make the resource configuration more reasonably optimized,reflecting the coordination in economy and reliability.
