用迁移反事实学习评估电力服务不公平

研究问题
面对混杂、反事实效应异质性和子群数据不足,如何评估人口属性对停电时长的因果影响并衡量电力服务不公平?
方法与思路
作者以受保护属性的平均因果效应衡量反事实不公平,结合子群分析和迁移学习,并应用于大规模客户层面的停电数据。
材料陈述的贡献
摘要称低收入和老年人口较多地区在日常及灾后运行中停电更久,严重情境下差异加剧,并提出缓解子群数据稀缺的方法。
阅读关注点
应核对人口属性对应的反事实干预、混杂控制与跨子群迁移条件,以及地区特征和客户结局之间的层级匹配及不确定性。
阅读边界
这是预印本,同行评审及期刊接收未获核验。摘要未说明识别假设、迁移条件或效应数值,其关于歧视的解释仍需全文证据支持。

原文摘要

Energy justice is a growing area of interest in interdisciplinary energy research. However, identifying systematic biases in the energy sector remains challenging due to confounding variables, intricate heterogeneity in counterfactual effects, and limited data availability. First, this paper demonstrates how one can evaluate counterfactual unfairness in a power system by analyzing the average causal effect of a specific protected attribute. Subsequently, we use subgroup analysis to handle model heterogeneity and introduce a novel method for estimating counterfactual unfairness based on transfer learning, which helps to alleviate the data scarcity in each subgroup. In our numerical analysis, we apply our method to a unique large-scale customer-level power outage data set and investigate the counterfactual effect of demographic factors, such as income and age of the population, on power outage durations. Our results indicate that low-income and elderly-populated areas consistently experience longer power outages under both daily and post-disaster operations, and such discrimination is exacerbated under severe conditions. These findings suggest a widespread, systematic issue of injustice in the power service systems and emphasize the necessity for focused interventions in disadvantaged communities.
