Distributed coordination for transmission-distribution systems with nonlinear flexibility aggregation
Xinliang Dai, Yanlin Jiang, Frederik Zahn +2
High shares of distributed energy resources (DERs) transform distribution systems into active participants in integrated transmission and distribution (ITD) operations. Linear mode…

Error Accumulation using Linearized Models for Aggregating Flexibility in Distribution Systems
Yanlin Jiang, Xinliang Dai, Frederik Zahn +2
This paper investigates flexibility aggregation approaches based on linear models. We begin by examining the theoretical foundations of linear AC power flow, two variants of so-cal…

Advancing Distributed AC Optimal Power Flow for Integrated Transmission-Distribution Systems
Xinliang Dai, Junyi Zhai, Yuning Jiang +3
This paper introduces a distributed operational solution for coordinating integrated transmission-distribution (ITD) systems regarding data privacy. To tackle the nonconvex challen…
