| 摘要: |
| 对电力系统动态负荷模型的集结进行了探讨和总结。考虑到噪声的未知特性，用辅助变量法对实测的负荷数据进行参数估计。并提出了用于三种情况下的基于参数辨识的模型集结方法：同一母线负荷模型集结，考虑线路阻抗的负荷模型集结和利用典型负荷模型参数集结。 |

| Abstract: |
| It describes the study for aggregation of dynamic load models.Based on analyzing the characteristics of the noise,an IV(Instrumental Variable)method is developed for identifying load parameters of difference equation models.We present aggregation methods in three cases:loads directly connected to a bus,loads connected to a bus through a feeder or transformer both field tests and National Dynamic Simulation Lab are identified and aggregated.The methods are correct and effective. |
| Key words: dynamic loads,load modeling,aggregation,parameter identification |
