Performance of Single and Double-Integrator Networks over Directed Graphs
H. Giray Oral, Enrique Mallada, Dennice F. Gayme
This paper provides a framework to evaluate the performance of single and double integrator networks over arbitrary directed graphs. Adopting vehicular network terminology, we cons…
Dynamic Droop Approach for Storage-based Frequency Control
Yan Jiang, Eliza Cohn, Petr Vorobev +1
Transient frequency dips that follow sudden power imbalances --frequency Nadir-- represent a big challenge for frequency stability of low-inertia power systems. Since low inertia i…
What is the Largest Sparsity Pattern that Can Be Recovered by 1-Norm Minimization?
Mustafa D. Kaba, Mengnan Zhao, Rene Vidal +2
Much of the existing literature in sparse recovery is concerned with the following question: given a sparsity pattern and a corresponding regularizer, derive conditions on the dict…
Implicit Trajectory Planning for Feedback Linearizable Systems: A Time-varying Optimization Approach
Tianqi Zheng, John Simpson-Porco, Enrique Mallada
We develop an optimization-based framework for joint real-time trajectory planning and feedback control of feedback-linearizable systems. To achieve this goal, we define a target t…
Adversarial Model Predictive Control via Second-Order Cone Programming
James Guthrie, Enrique Mallada
We study the problem of designing attacks to safety-critical systems in which the adversary seeks to maximize the overall system cost within a model predictive control framework. A…
Accurate Reduced-Order Models for Heterogeneous Coherent Generators
Hancheng Min, Fernando Paganini, Enrique Mallada
We introduce a novel framework to approximate the aggregate frequency dynamics of coherent generators. By leveraging recent results on dynamics concentration of tightly connected n…
Dynamic Droop Control in Low-inertia Power Systems
Yan Jiang, Richard Pates, Enrique Mallada
A widely embraced approach to mitigate the dynamic degradation in low-inertia power systems is to mimic generation response using grid-connected inverters to restore the grid's sti…
Global analysis of synchronization performance for power systems: bridging the theory-practice gap
Fernando Paganini, Enrique Mallada
The issue of synchronization in the power grid is receiving renewed attention, as new energy sources with different dynamics enter the picture. Global metrics have been proposed to…
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…
Dynamics Concentration of Large-Scale Tightly-Connected Networks
Hancheng Min, Enrique Mallada
The ability to achieve coordinated behavior --engineered or emergent-- on networked systems has attracted widespread interest over several fields. This has led to remarkable advanc…
Online Inventory Management with Application to Energy Procurement in Data Centers
Lin Yang, Mohammad H. Hajiesmaili, Ramesh Sitaraman +3
Motivated by the application of energy storage management in electricity markets, this paper considers the problem of online linear programming with inventory management constraint…
