Large-Scale Data Center Integration in Power Systems: Uncertainty and Multi-Scale Variation
Le Xie, Dongjoo Kim, Qian Zhang +2
Hyperscale artificial intelligence (AI) data centers are emerging as a structurally new class of electricity demand. Unlike conventional loads, they materialize as spatially concen…
Duration-Aware Ramp Adequacy Screening
Qian Zhang, Aidan Looney, Chao Tian +2
Ramp products are widely used in regional electricity markets to procure intertemporal flexibility in anticipation of net demand changes. However, the design of such ramp products…
Locational Marginal Pricing for Adaptive Robust Look-Ahead Dispatch with Casual Affine Recourse
Aidan Looney, Qian Zhang, Le Xie
This paper develops a marginal pricing mechanism for adaptive robust look-ahead economic dispatch (LAED) under net-load uncertainty. In current market practice, deterministic multi…
Lost Opportunity Costs Under Ramp Stress: A Comparison of Ramp-Product Dispatch and Look-Ahead Economic Dispatch
Aidan Looney, Qian Zhang, Le Xie
This paper studies whether ramp-product settlement compensates generators that absorb intertemporal ramp scarcity as effectively as look-ahead economic dispatch. We evaluate this q…
PowerAgentBench-Dyn: A Benchmark for Agentic AI in Power System Dynamic Studies
Qian Zhang, Andrea Pomarico, Costas Mylonas +3
Large Language Model (LLM)-based agents are increasingly being used to automate multi-step engineering work flows by interacting with software tools, interpreting intermediate resu…
Modeling Coincident Peak Pricing in Electricity Markets: Challenges and Peak Shaving Effectiveness
Qian Zhang, Sadie Zhao, Lucy Diao +4
Coincident Peak (CP) pricing is widely used in U.S. electricity markets to allocate capacity and transmission costs. This paper develops a behavioral game-theoretic framework for C…
Comparative Assessment of Look-Ahead Economic Dispatch and Ramp Products for Grid Flexibility
Qian Zhang, Le Xie, Long Zhao +1
High renewable penetration increases the frequency and magnitude of net-load ramps, stressing real-time flexibility. Two commonly deployed remedies are look-ahead economic dispatch…
A Gradient-Based Capacity Accreditation Framework in Resource Adequacy: Formulation, Computation, and Practical Implications
Qian Zhang, Feng Zhao, Gord Stephen +2
Probabilistic resource adequacy assessment is a cornerstone of modern capacity accreditation. This paper develops a gradient-based framework, in which capacity accreditation is int…
Reformulating Energy Storage Capacity Accreditation Problem with Marginal Reliability Impact
Qian Zhang, Feng Zhao, Tongxin Zheng +1
To enhance the efficiency of capacity markets, many electricity markets in the U.S. are adopting or planning to implement marginal capacity accreditation reforms. This paper provid…
