Robust Unit Commitment Model Based on Optimal Uncertainty Set

open access: yesIEEE Access, 2020
This article proposes a robust unit commitment (RUC) model for multiple types of energy sources based on the optimal uncertainty set. These energy sources are wind farms, thermal, hydro, natural gas, nuclear, and pumped-storage hydro power plants.
