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…
Wasserstein Geometry of Information Loss in Nonlinear Dynamical Systems
Yiting Duan, Zhikun Zhang, Yi Guo
Time-delay embedding is a powerful technique for reconstructing the dynamics of nonlinear systems. However, the reconstruction map is not always an embedding, a condition rarely ve…
Distributed AC Optimal Power Flow: A Scalable Solution for Large-Scale Problems
Xinliang Dai, Yuning Jiang, Yi Guo +3
This paper introduces a novel distributed optimization framework for large-scale AC Optimal Power Flow (OPF) problems, offering both theoretical convergence guarantees and rapid co…
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…
