| 摘 要： | 供电商实施可中断负荷管理的主要收益来自负荷需求水平的变动对现货电价的影响。使用条件风险价值作为风险度量工具,建立了同时考虑低电价可中断负荷合同和高补偿可中断负荷合同的供电商负荷削减决策模型,使用基于蒙特卡洛随机模拟的遗传算法对模型进行了求解,分析了不同负荷需求水平下供电商的负荷削减策略。结果表明:考虑可中断负荷对现货电价影响时供电商的负荷削减策略将更加激进,高补偿可中断负荷总是在低电价可中断负荷的削减量达到合同规定的最大值后才开始实施;利用低电价可中断负荷和高补偿可中断负荷的经济互补特性可获得比单独实施任何一种中断管理方式更大的收益。

| Abstract: | The main revenue of power supplier who implements interruptible load management is from the impact of the variation of load demand level on spot price. Using conditional value-at-risk (CVaR) as the measuring index of risk a load shedding decision model of power supplier in which both contract for interruptible load with low price (ILL) and that for interruptible load with high compensation price (ILH) are simultaneously considered,is built and solved by genetic algorithm based on Monte Carlo stochastic simu... |
