Grid-Interactive Operation of Solar-Integrated Data Centers for Coordinated Local and System-Level Decarbonization
Mingxu Yang, Weiqi Zhang, Hui Geng +1
The exponential growth of AI is accelerating the deployment of data centers (DCs), placing unprecedented strain on power infrastructures. In response, major IT corporations are inc…
Quantifying Space-Time Load Shifting Flexibility in Electricity Markets
Weiqi Zhang, Victor M. Zavala
The power grid is undergoing significant restructuring driven by the adoption of wind/solar power and the incorporation of new flexible technologies that can shift load in space an…
Pricing and Remunerating Electricity Storage Flexibility Using Virtual Links
Weiqi Zhang, Philip A. Tominac, Victor M. Zavala
Ambitious renewable portfolio standards motivate the incorporation of energy storage resources (ESR) as sources of flexibility. While the United States government aims to promote E…
Exploring the Impacts of Power Grid Signals on Data Center Operations using a Receding-Horizon Scheduling Model
Weiqi Zhang, Line A. Roald, Victor M. Zavala
Data centers (DCs) can help decarbonize the power grid by helping absorb renewable power (e.g., wind and solar) due to their ability to shift power loads across space and time. How…
A Unifying Modeling Abstraction for Infinite-Dimensional Optimization
Joshua L. Pulsipher, Weiqi Zhang, Tyler J. Hongisto +1
Infinite-dimensional optimization (InfiniteOpt) problems involve modeling components (variables, objectives, and constraints) that are functions defined over infinite-dimensional d…
Spatio-Temporal Economic Properties of Multi-Product Supply Chains
Philip A. Tominac, Weiqi Zhang, Victor M. Zavala
In this work, we analyze the spatio-temporal economic properties of multi-product supply chains. Specifically, we interpret the supply chain as a coordinated market in which stakeh…
Remunerating Space-Time, Load-Shifting Flexibility from Data Centers in Electricity Markets
Weiqi Zhang, Victor M. Zavala
We study an electricity market clearing formulation that seeks to remunerate spatio-temporal, load-shifting flexibility provided by data centers (DaCes). Load-shifting flexibility…
On the Tightness of the Lagrangian Dual Bound for Alternating Current Optimal Power Flow
Weiqi Zhang, Kibaek Kim, Victor M. Zavala
We study tightness properties of a Lagrangian dual (LD) bound for the nonconvex alternating current optimal power flow (ACOPF) problem. We show an LD bound that can be computed in…
Flexibility from Networks of Data Centers: A Market Clearing Formulation with Virtual Links
Weiqi Zhang, Line A. Roald, Andrew A. Chien +2
Data centers owned and operated by large companies have a high power consumption and this is expected to increase in the future. However, the ability to shift computing loads geogr…
