基于时序运行模拟的新能源电力系统典型场景生成方法
A typical scenario generation method for renewable energy power systems based on time-sequenced operational simulations
摘要
Abstract
Traditional clustering methods based on source-load information struggle to accurately describe the time-sequenced operational characteristics of renewable energy power systems.To address this,a typical scenario genera-tion method for renewable energy power systems based on time-sequenced operational simulations is proposed,con-sidering both the AC power flow distribution and startup-shutoff strategies for units.Firstly,a unit combination model that incorporates AC power flow constraints is constructed,and a two-stage solution strategy based on second-order cone relaxation is adopted to perform 8,760-hour time-sequenced simulations in the multi-period optimal power flow model.Secondly,based on data characteristics such as renewable energy output levels,line congestion conditions,and unit startup-shutoff from the time-sequenced simulation results,an improved K-means algorithm is employed to extract typical scenarios.Finally,the validity of the proposed method is verified through a case study,providing a reference for renewable energy power system planning and scheduling.关键词
