Distributionally Robust Federated Learning with Multi-Source Data
Yingzhu Liu, Zhongkui Li, Pengcheng You +1
Federated learning trains a shared model from private client data. In practice, data-generating distributions may differ, and the true mixture across clients is often unknown, maki…
Learning-Augmented Primal-Dual Control Design for Secondary Frequency Regulation
Yixuan Yu, Rajni K. Bansal, Yan Jiang +1
Frequency stability is fundamental to the secure operation of power systems. With growing uncertainty and volatility introduced by renewable generation, secondary frequency regulat…
Coherency Analysis in Nonlinear Heterogeneous Power Networks: A Blended Dynamics Approach
Yixuan Liu, Yingzhu Liu, Pengcheng You
Power system coherency refers to the phenomenon that machines in a power network exhibit similar frequency responses after disturbances, and is foundational for model reduction and…
Decision-Dependent Distributionally Robust Optimization with Application to Dynamic Pricing
Chengrui Qu, Huiwen Jia, Pengcheng You
We consider decision-making problems under decision-dependent uncertainty (DDU), where the distribution of uncertain parameters depends on the decision variables and is only observ…
A Unified Analysis of Saddle Flow Dynamics: Stability and Algorithm Design
Pengcheng You, Yingzhu Liu, Enrique Mallada
This work examines the conditions for asymptotic and exponential convergence of saddle flow dynamics of convex-concave functions. First, we propose an observability-based certifica…
Robust Aggregation of Electric Vehicle Flexiblity
Karan Mukhi, Chengrui Qu, Pengcheng You +1
We address the problem of characterizing the aggregate flexibility in populations of electric vehicles (EVs) with uncertain charging requirements. Extending upon prior results that…
Online Electricity Purchase for Data Center with Dynamic Virtual Battery from Flexibility Aggregation
Kekun Gao, Yuejun Yan, Yixuan Liu +2
As a critical component of modern infrastructure, data centers account for a huge amount of power consumption and greenhouse gas emission. This paper studies the electricity purcha…
Dissipative Gradient Descent Ascent Method: A Control Theory Inspired Algorithm for Min-max Optimization
Tianqi Zheng, Nicolas Loizou, Pengcheng You +1
Gradient Descent Ascent (GDA) methods for min-max optimization problems typically produce oscillatory behavior that can lead to instability, e.g., in bilinear settings. To address…
Intercept Function and Quantity Bidding in Two-stage Electricity Market with Market Power Mitigation
Rajni Kant Bansal, Yue Chen, Pengcheng You +1
Electricity markets typically operate in two stages, day-ahead and real-time. Despite best efforts striving efficiency, evidence of price manipulation has called for system-level m…
Market Power Mitigation in Two-stage Electricity Market with Supply Function and Quantity Bidding
Rajni Kant Bansal, Yue Chen, Pengcheng You +1
The main goal of a sequential two-stage electricity market -- e.g., day-ahead and real-time markets -- is to operate efficiently. However, the price difference across stages due to…
Constrained Reinforcement Learning via Dissipative Saddle Flow Dynamics
Tianqi Zheng, Pengcheng You, Enrique Mallada
In constrained reinforcement learning (C-RL), an agent seeks to learn from the environment a policy that maximizes the expected cumulative reward while satisfying minimum requireme…
On the Stability, Economic Efficiency and Incentive Compatibility of Electricity Market Dynamics
Pengcheng You, Yan Jiang, Enoch Yeung +2
This paper focuses on the operation of an electricity market that accounts for participants that bid at a sub-minute timescale. To that end, we model the market-clearing process as…
A Market Mechanism for Truthful Bidding with Energy Storage
Rajni Kant Bansal, Pengcheng You, Dennice F. Gayme +1
This paper proposes a market mechanism for multi-interval electricity markets with generator and storage participants. Drawing ideas from supply function bidding, we introduce a no…
Mechanism Design for Efficient Nash Equilibrium in Oligopolistic Markets
Kaiying Lin, Beibei Wang, Pengcheng You
This paper investigates the efficiency loss in social cost caused by strategic bidding behavior of individual participants in a supply-demand balancing market, and proposes a mecha…
Storage Degradation Aware Economic Dispatch
R. K. Bansal, P. You, D. F. Gayme +1
In this paper, we formulate a cycling cost aware economic dispatch problem that co-optimizes generation and storage dispatch while taking into account cycle based storage degradati…
Saddle Flow Dynamics: Observable Certificates and Separable Regularization
Pengcheng You, Enrique Mallada
This paper proposes a certificate, rooted in observability, for asymptotic convergence of saddle flow dynamics of convex-concave functions to a saddle point. This observable certif…
The Role of Strategic Load Participants in Two-Stage Settlement Electricity Markets
Pengcheng You, Dennice F. Gayme, Enrique Mallada
Two-stage electricity market clearing is designed to maintain market efficiency under ideal conditions, e.g., perfect forecast and nonstrategic generation. This work demonstrates t…
Scheduling of EV Battery Swapping, II: Distributed Solutions
Pengcheng You, Steven H. Low, Liang Zhang +4
In Part I of this paper we formulate an optimal scheduling problem for battery swapping that assigns to each electric vehicle (EV) a best station to swap its depleted battery based…
