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…
PowerAgentBench-SS: A Benchmark for Agentic AI in Power System Steady-State Studies
Costas Mylonas, Magda Foti, Andrea Pomarico +3
Power system benchmarks usually evaluate numerical solvers, prediction models, or sequential controllers. These benchmarks are necessary, but they do not directly test whether a La…
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…
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…
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…
