电力系统非机理负荷模型的可辨识性

Identifiability of Usual I/O Load Models in Power Systems

主要研究了ＩＥＥＥ工作组公布的常用电力负荷非机理模型的可辨识性问题———这些模型的参数能否根据测量数据唯一获得．对每一种模型都得出了明确结果．结果表明，一些常见负荷模型是不可辨识的，必须采用统计综合法或增加附加信息．研究结果对今后进一步的研究和应用工作具有重要的参考价值．

This paper studies the identifiability problems of the usual I/O load models recognized by IEEE Task Force, i.e. whether the parameters of the models are uniquely identifiable. Each nodel is studied, and the results show that some models are not identifiable and new information should be added. The study is beneficial to further research.
