摘要
In the robust unit commitment, how to rationally describe the uncertain power of renewable energy sources plays an important role in determining the conservativeness of the model. In this paper, the data-driven generalized convex hull uncertainty set was proposed and applied to the two-stage robust unit commitment. This model can effectively consider the temporal and spatial correlations of renewable energy sources, thus reducing the conservativeness of the decision and improve the economy. Firstly, the historical data of the renewable energies was used to construct the data-adaptive uncertainty set and exact the extreme scenarios. Then, the two-stage robust unit commitment model based on the extracted extreme scenarios was introduced. Furthermore, the column and constraint generation algorithm was employed to solve the robust model. Finally, the proposed model and solution technique were tested on a 14-bus and a modified IEEE RTS-79 system. The numerical results showed the effectiveness of the proposed model and solution method. © 2020 Chin. Soc. for Elec. Eng.
