Multi-period Uncertainty Set Modeling Method for Wind Farms Applicable to Robust Control
摘要
Abstract
Reasonably characterizing the closed set of wind farm output uncertainty is the foundation for achieving robust control of power grid.Based on the quantitative laws of impact of the wind farms on stability,this paper proposes an improved data processing method that significantly reduces the risk of stability control.For modeling multi-wind farm and multi-period uncertainties,the spatio-temporal correlation of output errors and the impact of ramping errors on reserve configuration are comprehensively considered.A convex uncertainty set is constructed using wide-area ellipsoidal and hyperplane constraints.Furthermore,a parameter solution method based on high-dimensional volume minimization is proposed,which coordinates relevant constraint boundaries to ensure the model satisfies multiple preset confidence probabilities.Finally,the proposed method is validated using actual wind farm data.The results show that this method reduces the volume of the uncertainty set by 12%,effectively improving model accuracy and applicability.关键词
