Uncertainty has brought new challenges to the generation scheduling in power systems. Robust optimization has become one of the mainstream approaches for research on generation scheduling under uncertainty due to its unique advantages. The paper reviewed the application of robust optimization for generation scheduling in power systems. First, the uncertainties in generation scheduling problems and the existing approaches for handling uncertainties were summarized. Second, the theoretical foundation of robust optimization was briefly illustrated. Third, the application examples of the robust optimization in generation scheduling was described, and the robust scheduling problems considering three kind of typical uncertainties, including net injection uncertainty, contingency uncertainty and market uncertainty, were presented. Finally, key problems to be investigated and lines of future research for the robust generation scheduling were discussed.
