Coherency Analysis in Nonlinear Heterogeneous Power Networks—A Blended Dynamics Approach
Yixuan Liu, Yingzhu Liu, and Pengcheng You
A novel theoretical analysis of power system coherency. Reveals the key mechanisms underpinning this phenomenon, laying foundations for model reduction and further control design. (source of figure)
Robust Design and Analysis of Physics-Driven Electricity Market Dynamics
Ongoing project
Characterize the evolution of electricity markets using a dynamic system, with toolkits from control theory. Such perspective enables us to unify the grid's physical dynamics (e.g., frequency regulation) and its economic dispatch on the same timescale. Further considering the unpredictable and complex behaviors of real-world generators, we aim to use robust control to develop robust market mechanisms.
Online Electricity Purchase for Data Center with Dynamic Virtual Battery from Flexibility Aggregation
Kekun Gao, Yuejun Yan, Yixuan Liu, and Pengcheng You
A scalable algorithm for the real-time electricity purchase of data centers with mass heterogeneous flexible loads. Guarantee a near-optimal cost and strict satisfaction of operational constraints without relying on any predictions.
Reinforcement Learning Algorithm for Reusable Resource Allocation with Unknown Rental Time Distribution
Ziwei Wang, Jie Song, Yixuan Liu, and Jingtong Zhao
A novel RL algorithm for dynamic reusable resource allocation under uncertainty with theoretical guarantee. Outline the potential for systematically extending classical Approximate Dynamic Programming-based methods to online settings with unknown parameters.
