Abstract

Abstract : Wind power generation has constituted a major body of generation portfolio in many countries. In stormy weather conditions, however, wind power generation would be curtailed due to the over‐speed protection of wind turbines. In this study, the authors propose to apply the risk‐limiting unit commitment (UC) in a rolling framework to improve the efficient utilisation of wind power. The proposed method includes three modules, namely, day‐ahead UC, hourly‐ahead UC, and real‐time load shedding. The first module provides the baseline of hourly dispatch, whereas the latter two serve as recourse means applied during stormy event unfolding. Illustrative examples are provided, demonstrating that the proposed method will reduce the overall generation cost of the time horizon under consideration, as compared to conservative dispatch methods, by postponing the timing of proactive wind curtailment.
