Ramping Procurement and Bid-Cost Recovery in Real-Time Market
Cong Chen, Valentina Norambuena, Lang Tong
We study ramping procurement co-optimized with economic dispatch under net-demand uncertainty. We examine two flexible ramp product designs implemented by grid operators: single-in…
A Scalable Bundle Method for Exact Reformulation of SDP in Three-Phase Power Flow Feasibility
Bohang Fang, Lijun Ding, Cong Chen
Power flow feasibility assessment is computationally challenging for unbalanced three-phase distribution networks. This paper develops a vectorized semidefinite program (SDP) based…
Reachable-Set Decomposition for Real-Time Aggregation of Multi-Zone HVAC Fleets
Jingguan Liu, Xiaomeng Ai, Cong Chen +4
Aggregating building heating, ventilation, and air-conditioning (HVAC) fleets provides substantial real-time flexibility to power system operations. However, real-time aggregation…
Wholesale Market Participation via Competitive DER Aggregation
Cong Chen, Ahmed S. Alahmed, Timothy D. Mount +1
We consider the aggregation of distributed energy resources (DERs), such as solar PV, energy storage, and flexible loads, by a profit-seeking aggregator participating directly in t…
Risk-Aware Allocation of Transmission Capacity for AI Data Centers
Shaoze Li, Bohang Fang, Cong Chen
Rapid growth in AI-driven data center loads is creating significant challenges for transmission grid interconnection. This paper proposes robust and risk-aware frameworks to quanti…
Behavioral Generative Agents for Energy Operations
Cong Chen, Omer Karaduman, Xu Kuang
Problem definition: Accurately modeling consumer behavior in energy operations is challenging due to uncertainty, behavioral heterogeneity, and limited empirical data-particularly…
