Abstract

Operational uncertainties such as variation of power or grid impedance affect the level of conducted emission of power converters in renewable energy systems. This paper utilizes an enhanced Unscented Transform (UT) method based on dimension reduction technique to predict the conducted emissions of multiple Voltage Source Converters (VSCs) in the presence of uncertainties. The accuracy of the predicted results are then compared with the Monte Carlo Simulation approach and the traditional Unscented Transform.

利用降维技术预测多个VSCs的传导辐射
在可再生能源系统中,功率或电网阻抗的变化等运行不确定性会影响电源变流器的传导发射水平。本文利用基于降维技术的增强Unscented变换(UT)方法来预测存在不确定性的多电压源变换器(VSCs)的传导发射。将预测结果的准确性与蒙特卡罗模拟方法和传统的Unscented变换方法进行了比较。
