摘要

间歇性可再生能源发电厂，如光伏发电厂和风力发电厂，与大容量电力系统的整合已经改变了它们的运行和扩展方式。本文给出了考虑不同可再生能源接入水平和无功下垂控制的电力系统电压分布的评估方法。以6母线电力系统为例，考虑负荷需求和可再生能源发电小时曲线，进行了一系列的潮流仿真，得到了电压分布和发电无功功率。根据目前的电网规范要求，随着可再生能源的普及，电力系统的整体电压控制将趋于退化，因为无功下垂控制本身不足以适应负载需求行为，因为它们是间歇性的。

Power System Voltage Profile Evaluation Considering Renewable Energy Power Plant Reactive Power Droop Control

The integration of intermittent renewable energy power plants, such as photovoltaic and wind power plants, to bulk power systems has changed the way their operation and expansion is performed. In this paper, an evaluation of the voltage profile of a power system considering different levels of renewable penetration and their reactive power droop control is presented. A series of power flow simulations to obtain the voltage profile and the generation's reactive power were performed using a 6-bus power system considering load-demand and renewable generation hourly curves. Based on current grid code requirements, the overall voltage control of a power system will tend to degrade with increasing penetration of renewables, as reactive power droop control alone is not sufficient to accommodate load-demand behavior due to their intermittence.
