摘要
可中断负荷响应行为中的随机和模糊因素通常同时存在,即统计规律本身包含高阶不确定性,针对高阶不确定性背景下的聚合商调度决策问题,在可中断负荷传统的削减率模糊模型的基础上考虑其随机性,建立模糊随机机会约束规划模型,求解可中断负荷的最优响应容量,并进行相应的风险评估。计及高阶不确定性的模糊随机模型和传统的模糊模型的算例对比结果表明,计及高阶不确定性的决策方法更稳健,能减小调度决策的风险,体现了响应可靠性对决策者利润的影响,可为聚合商的调度提供指导。
The random and fuzzy factors usually exist simultaneously in the response behavior of interruptible load,that is the statistical law itself contains high-order uncertainty.Aiming at the dispatching decisionmaking problem of aggregators under the background of high-order uncertainty,the randomness of interruptible load is considered based on its traditional fuzzy model of reduction rate,a fuzzy random chance constrained programming model is established,the optimal response capacity of interruptible load is solved,and the cor⁃responding risk evaluation is carried out.The case result comparison between the fuzzy random model con⁃sidering high-order uncertainty and the traditional fuzzy model shows that the decision-making method con⁃sidering high-order uncertainty is more robust and can reduce the risk of dispatching decision-decision,which reflects the impact of response reliability on decision-maker’s profit and can present a guide for load aggregators.
