【摘要】 基于MATLAB仿真工具并运用总体测辨建模原理,研究了风力发电对配电网侧综合负荷建模的影响。指出含风力发电的配电网侧综合负荷可以用异步电机并联静态负荷的广义综合负荷模型来等效描述;为了准确反映风力发电容量对综合负荷模型的影响,模型中的动态负荷所占比例的取值范围必须扩大到任意实数。对3种典型运行方式的建模表明,所提出的任意动态负荷比例的异步电机并联静态负荷的综合负荷模型,对不同风力发电容量和负荷水平的配电网综合负荷特性有很好的等效描述能力。更多还原

【Abstract】 The impact of wind power generation on the load modeling in the distribution network is studied using MATLAB and based on measurement-based method.It is pointed out that the synthetic load of distribution network including wind power generation can be described by a generalized composite load model combining asynchronous machines and static loads.To precisely reflect the impact of wind power generation on the composite load model,the percentage of dynamic load must be extended to any real number.The validity of this composite load model of any percentage of dynamic load is testified by modeling three typical operation styles with different compositions of wind power generation and load.更多还原
