Abstract

One of the main issues concerning large penetration of the renewable energy based generators on the distribution network is related to the voltage variations due to intermittent character of the solar irradiance and wind. The actual power quality standards provide only general information regarding the evaluation procedure of the voltage fluctuations and no directions regarding the sampling frequency of the data used. As a consequence, most of the studies neglect effect of the solar irradiance and wind speed in fast changing conditions on the utility grid. This work proposes a methodology to evaluate the voltage fluctuations into the low voltage distribution network caused by variable generation and reveals the influence of data resolution on the final results. A short review regarding the assessment of the voltage variations is presented in advance and an appropriate model of the power system is build, including the generating units that are capable to operate with high resolution input data. Real parameters for the components of the simulated system are used in order to obtain realistic results.

输入数据分辨率对分布式发电集成研究的影响

可再生能源发电机组在配电网中大规模渗透的主要问题之一是由于太阳辐照度和风的间歇性特性而引起的电压变化。实际的电能质量标准只提供关于电压波动评估程序的一般信息，而没有关于所使用数据的采样频率的说明。因此，大多数研究忽略了快速变化条件下太阳辐照度和风速对电网的影响。本文提出了一种评估由变量产生引起的低压配电网电压波动的方法，并揭示了数据分辨率对最终结果的影响。对电压变化的评估进行了简要回顾，并建立了一个适当的电力系统模型，包括能够以高分辨率输入数据运行的发电机组。为了得到真实的仿真结果，采用了仿真系统各部件的真实参数。
