兼顾风-光-荷不确定性与相关性的配电网多目标重构方法
A multi-objective reconfiguration method for distribution networks considering the wind-photovoltaic-load uncertainty and correlation
摘要
Abstract
With the advancement of new-type power systems,the large-scale integration of distributed generation(DG)poses challenges to the optimal operation of distribution networks.In response,a multi-objective reconfigura-tion method for distribution networks is proposed,which takes account of the wind-photovoltaic-load uncertainty and correlation.The Copula theory is applied to construct a correlation model,and wind speed-irradiance-load correla-tion samples are obtained through Spearman's rank correlation coefficient.By introducing complex network theory,the paper addresses the network vulnerability considering the intermittency of wind and photovoltaic output powers.To minimize network losses,network vulnerability,and switching times of switchgears at a certain confidence level,a multi-objective coordinated optimization reconfiguration model considering the uncertainty of wind,solar,and load output is established based on chance-constrained programming,and a parameter adaptive algorithm is ap-plied to solve the model.Case studies verify that the proposed method can balance effectiveness and usability.关键词
