摘要

研究了配网侧接入电源对负荷建模的影响。发现当配网侧电源的发电容量逐渐增大时，原有的感应电动机并联恒阻抗、恒电流、恒功率（ZIP）模型的负荷模型将不再能很好地反映该区域的负荷特性，进而提出了一种新的负荷模型结构———异步发电机并联ZIP模型。通过仿真计算，验证了该新负荷模型的有效性，并进一步统一了上述2种负荷模型，称为异步机并联ZIP负荷模型。

Abstract

This paper studies the impact of connecting power sources on the load modeling in a distribution network， finding that when the impact is not negligible， the composite induction motor load model will no longer be able to effectively describe the actual load characteristic. So a new load model is presented， which the authors choose to call the asynchronous generator plus ZIP model. The validity of this new load model is testified by simulation calculations. Furthermore， a composite load model for the induction motor and asynchronous generator plus ZIP model is presented.
