| Abstract: | Incorporating wind power forecast in power system operation is one of the main techniques for mitigating the fluctuation of wind power variation.Because of changes of weather,however,it is still a challenge to make highly accurate wind power forecast.By describing the uncertainty of wind power forecast and using it in unit commitment(UC) will help make more robust day-ahead schedules.Three categories of wind forecast information are described in this paper.A modified UC model is proposed that can be flexibly adapted to each type of wind power forecast information.Ten units from an IEEE-RTS 96 system are selected to test the proposed model.Simulation results show the effectiveness of the model in using different wind power forecast information.In addition,occasional wind curtailment may help system operate more economically. |
