摘　　要：新能源送出系统的灵活异构对电力系统仿真技术提出更高要求,目前仍未建立针对新能源送出系统仿真模型的适应性准则和准确度评价体系。构建一种基于类比迁移的新能源送出系统多场景仿真模型评价体系,对特征电气量曲线进行时间窗口划分与特征点集选取,进而确定多场景下的模型评价指标;在PSCAD/EMTDC中,以风电场送出系统为例,搭建3类风电场模型展开仿真测试,验证评价指标,并结合置信区间量化误差阈值;将评价指标及误差阈值等推广应用到工程实际。所提评价体系通过类比迁移实现了多场景的仿真模型准确度评价,可以应用于工程实际,准确度评价指标和误差阈值更加全面客观。The flexibilities and heterogeneity of renewable energy delivery system have put forward higher requirements for power system simulation technology.At present,the adaptability criteria and accuracy evaluation system for the simulation model of renewable energy delivery system have not been established.A multi-scenario simulation model evaluation system for renewable energy delivery system based on analogical transfer is proposed.The characteristic electrical quantity curve divided into time windows and feature point sets are selected to determine the model evaluation indexes for multiple scenarios and operating conditions.In PSCAD/EMTDC,taking the wind farm delivery system as an example,three types of wind farm models are built,and the evaluation indexes are verified,quantifying the error threshold with the confidence interval.The evaluation indicators and error thresholds are extended and applied to engineering practice.The proposed evaluation system realizes the accuracy evaluation of multi-scenario simulation model through analogical transfer,which can be applied to engineering practice,and the accuracy evaluation indexes and error thresholds are more comprehensive and objective.
