Robust Chance-constrained Security Region Model of AC/DC Hybrid Distribution Network Considering the Uncertainty of Photovoltaic Generation
摘要
Abstract
To realize the security evaluation of AC/DC hybrid distribution network with the high penetrations of photovoltaic generation,a robust chance-constrained security region model of AC/DC hybrid distribution network is constructed.First,an adaptive bandwidth kernel density estimation method based on the interval division is proposed,and the photovoltaic output chance-constrained uncertainty set is constructed based on the probability distribution of photovoltaic forecast error.Next,a linear branch power flow model for AC/DC hybrid distribution network is derived based on the AC linear power flow model by taking the ratio of power and node voltage amplitude as state variables.Then,the model of the robust chance-constrained security region of the AC/DC hybrid distribution network is developed,and the robust chance-constrainted security region boundary points are obtained based on the combination of the column and constraint generation algorithm and the radial iterative search algorithm.Consequently,the robust chance-constrained security region of AC-DC hybrid distribution networks is visualized.Finally,numerical results verify that the proposed model can accurately and intuitively reflect the randomness of photovoltaic generation in the robust chance-constrained security region,which positively contributes to the accurate security evaluation of the AC-DC hybrid distribution network.关键词
