TRACE: A Reproducible Benchmark for Electricity Price Forecasting with Official Operational Text
Xinyi Yi, Zhangdie Yuan, Moy Yuan +1
Electricity price forecasting (EPF) supports scheduling, bidding, and risk management in electricity markets, yet existing benchmarks focus mainly on numerical inputs, leaving the…
LiFT-MPC: Language-in-the-Loop Feedback Tuning of Cost Previews for MPC
Xinyi Yi, Ioannis Lestas
In model predictive control (MPC) with time-varying objectives, predicted signals need to be often incorporated in the cost function, such as prices in energy system operation. The…
Data-driven online control for real-time optimal economic dispatch and temperature regulation in district heating systems
Xinyi Yi, Ioannis Lestas
District heating systems (DHSs) require coordinated economic dispatch and temperature regulation under uncertain operating conditions. Existing DHS operation strategies often rely…
A mixed Hinfty-Passivity approach for Leveraging District Heating Systems as Frequency Ancillary Service in Electric Power Systems
Xinyi Yi, Ioannis Lestas
This paper introduces a mixed H-infinity-passivity framework that enables district heating systems (DHSs) with heat pumps to support electric-grid frequency regulation. The analysi…
Energy-grade double pricing mechanism for a combined heat and power system using the asynchronous dispatch method
Xinyi Yi, Ye Guo, Hongbin Sun +2
The problem of heat and electricity pricing in combined heat and power systems regarding the time scales of electricity and heat, as well as thermal energy quality, is studied. Bas…
Energy-Grade Double Pricing Rule in the Heating Market
Xinyi Yi, Ye Guo, Hongbin Sun
The problem of heat system pricing is considered. A direct extension of locational marginal prices (LMP) in electricity markets to heat systems may lead to revenue inadequate issue…
