摘要

根据负荷具有的自身特点,对实际电网中如何提高负荷模型的实用性进行了研究。提出首先应用聚类分析的方法对负荷进行分类,以消除由于负荷时变性对建模造成的影响;然后应用多曲线拟合的方法对模型进行综合来达到减少模型个数的目的;最后通过轨迹灵敏度的方法对参数进行简化,最终得到实用性较强的负荷模型,从而解决了困扰负荷模型推广应用所面临的问题,为模型的实用化提供了借鉴。

Abstract:

In the light of special characteristic of the load, it is researched how to improve the practicality of the load model in actual power grid. It is proposed that firstly the power load should be classified by cluster analysis to eliminate the influence of time variability of power load on load modeling; then the models should be synthesized by use of multi-curve fitting to reach the aim of reducing the number of models; and then by means of trajectory sensitivity the parameters of the model are simplified; finally a practicable load model is attained, thus the problems causing troubles during the application and dissemination of load model can be solved.
