价格信号引导下,居民柔性负荷具备可观的需求响应潜力,但受有限理性因素影响,其响应行为存在较大的不确定性。针对这一问题,提出一种小样本数据驱动的不确定性建模方法。该方法通过挖掘居民柔性负荷响应与其协变量之间的时变耦合特性,动态更新条件概率分布参数,从而有效缩窄高概率取值区间并提升不确定性刻画精度。在此基础上,构建面向新型配电系统的两阶段随机调度模型,采用条件风险价值量化尾部风险,并利用Benders分解算法降低模型求解复杂度。最后,基于改进的IEEE 33节点和IEEE 123节点测试系统开展数值分析。结果表明,所提方法能在经济性、风险规避能力与计算可行性之间实现较优平衡,为考虑居民柔性负荷响应不确定性的新型配电系统源-网-荷-储协同优化提供技术支撑。
Guided by price signals
residential flexible loads exhibit considerable demand response potential
but their response behaviors are subject to substantial uncertainty due to bounded rationality. To address this issue
a few-shot data-driven uncertainty modeling method is proposed. By exploring the time-varying coupling characteristics between residential flexible load response and its covariates
the method dynamically updates the parameters of conditional probability distributions
thereby effectively narrowing high-probability value intervals and improving the accuracy of uncertainty characterization. On this basis
a two-stage stochastic scheduling model for new distribution systems is developed
in which the conditional value at risk (CVaR) is adopted to quantify the tail risk
and the Benders decomposition algorithm is used to reduce the model solving complexity. Finally
numerical analysis is carried out on the modified IEEE 33-bus and IEEE 123-bus test systems. Results demonstrate that the proposed method can achieve a favorable balance among economic performance
risk aversion capability
and computational feasibility
thereby providing technical support for the coordinated optimization of “source-grid-load-storage” in new distribution systems considering the uncertainty of residential flexible load response.
