Impact of Wind Power Forecast Information on Power System Day-Ahead Scheduling and Its Applicability
Wind power point and interval forecasting methods have been widely applied in current power system scheduling and operation.This paper establishes the wind power forecast model based on the existing wind power forecasting techniques.Besides,it builds up the day-ahead unit commitment model considering the distinct types of wind power prediction information.Then,the stochastic simulation of wind power is applied to analyze the distinction between different forecast information in the system scheduling program,with a focus on the impact of the scenarios reduction techniques and probability interval value selection on the individual and total cost of power system scheduling program.The calculation example shows that the application of wind power scenario forecast information in scheduling scheme is superior to the application of wind power interval forecast information in economic aspects.And the description of scenario probability and distance is the key factor for the effect of wind power scenario forecast while there is an optimal range of the confidence interval among the wind power interval forecast and equilibrium of economy and robustness can be achieved in this case.
