由于消费者越来越多地参与能源市场以及分布式能源（DER），电动汽车（EV）和本地储能系统（ESS）等新技术的适应，配电系统规划和运营已经发生了许多结构性变化。尽管这些技术很方便，而且价格也逐渐下降，但新的技术挑战（例如，过多的功率损耗）已经出现在系统级。在过去的几十年中，配电系统中的功率损耗最小化已经得到普及，并且需要损耗敏感性分析（LSA）框架已经成为其成功实施的必要条件。LSA的现有工作主要集中在系统规划方面，通过DER优化布局和规模。然而，启用基于LSA的系统操作应用程序是成功过渡到现代配电系统（MDS）的关键一步。因此，本文提出了一个全面的概述最先进的LSA的MDS。首先，总结了现有的LSA方法的理论公式。然后，重点介绍了LSA在配电系统中的应用。最后，在文献分析的基础上，对研究的空白和未来的研究方向进行了展望。
Distribution system planning and operation has seen many structural changes due to the increased participation of consumers in the energy market and the adaptation of new technologies such as distributed energy resources (DERs), electric vehicles (EV) and local energy storage systems (ESSs). Despite the convenience of such technologies and the gradual drop in their prices, new technical challenges (e.g., excessive power losses) have emerged at the system level. Over the past few decades, power loss minimization in distribution systems has gained popularity and the need for loss sensitivity analysis (LSA) frameworks has become a necessity for its successful implementation. Existing work on LSA mostly focuses on system planning aspects through DER optimal placement and sizing. However, enabling LSA-based system operational applications is a vital step toward the successful transition to modern distribution systems (MDSs). Therefore, this paper presents a comprehensive overview on the state of the art in LSA for MDSs. First, the theoretical formulations of existing LSA methods are summarized. Then, the applications of LSA in distribution systems are highlighted. Finally, based on the analysis of literature, open research gaps and future research pathways are discussed.
