Risk-Averse Markov Decision Processes: Applications to Electricity Grid and Reservoir Management
Arash Khojaste, Jonathan Pearce, Daniela Pucci de Farias +2
This paper develops risk-averse models to support system operators in planning and operating the electricity grid under uncertainty from renewable power generation. We incorporate…
Electricity Price-Aware Scheduling of Data Center Cooling
Arash Khojaste, Jonathan Pearce, Golbon Zakeri +1
Data centers are becoming a major consumer of electricity on the grid, with cooling accounting for about 40\% of that energy. As electricity prices vary throughout the day and year…
Baseline hydropower generation offer curves
Jonathan Pearce, Arash Khojaste, Golbon Zakeri +1
We outline a mathematical model for pricing hydropower generation. The model involves a Markov decision process that reflects the seasonal variation in historical time series of wa…
Quantile Fourier regressions for decision making under uncertainty
Arash Khojaste, Geoffrey Pritchard, Golbon Zakeri
Weconsider Markov decision processes arising from a Markov model of an underlying natural phenomenon. Such phenomena are usually periodic (e.g. annual) in time, and so the Markov p…
