Abstract

This study developed a methodology to determine zones of acceptable voltage profiles for wind power generation connected to distribution systems. Three load profiles (residential, commercial and industrial) connected to the distribution network were analyzed considering the impact on voltage levels and steady-state stability for different wind speeds and wind generator control strategies. The wind generator model is based on doubly fed induction generator (DFIG) and were developed using Matlab/Simulink. The presented methodology can be used to map the impact on operation of different types of control, the time of day and the available wind speed and it is not limited only for DFIG. The results have shown that the methodology helps to find zones were the combination of wind speed, load demand and control strategy can lead the system to voltage levels outside the standard limits. The determination of these zones of inoperability helps the utilities to avoid and prevent the system from fail.

一种基于DFIG的分布式发电运行区域评估方法

本研究开发了一种方法来确定连接到配电系统的风力发电的可接受电压分布区域。考虑了不同风速和风力发电机控制策略对配电网电压水平和稳态稳定性的影响，分析了接入配电网的三个负荷剖面(住宅、商业和工业)。风力发电机模型基于双馈感应发电机(DFIG)，采用Matlab/Simulink开发。所提出的方法可用于绘制不同类型的控制、一天中的时间和可用风速对运行的影响，并且不仅限于DFIG。结果表明，该方法有助于找到风速、负载需求和控制策略的组合可能导致系统电压水平超出标准限制的区域。确定这些不可操作区域有助于公用事业公司避免和防止系统发生故障。
