Abstract

The major focus of the conversation in this investigation is on the impact that voltage-source converter harmonics have on the power quality Power Quality (PQ) of a microgrid. The degree of harmonic distortion that is generated by several Voltage Source Converters (VSCs) may drastically change when there are uncertainties present, and its behavior might be difficult to anticipate as a result of these changes. These uncertainties might result from the design parameters’ selection or system parameters’ modification. Because of this, it is necessary to make use of statistical methods to measure the degrees of VSC harmonic distortion when there are uncertainties present. A practical microgrid lab consisting of three VSCs was also used to experimentally evaluate the Univariate Dimension Reduction (UDR’s) performance. The Monte Carlo Simulation (MCS) method served as a standard for judging the accuracy of the expected UDR outcomes. In every instance, the anticipated outcomes of the UDR were attained with significant time savings in comparison to the approach taken by the MCS, and the results of the UDR demonstrated a good match with the strategy taken by the MCS.
电力系统(微电网)中多台变流器引起的随机谐波畸变研究与分析
本研究的主要焦点是电压源转换器谐波对微电网电能质量(PQ)的影响。当存在不确定性时,由几个电压源转换器(VSCs)产生的谐波失真程度可能会发生巨大变化,并且由于这些变化,其行为可能难以预测。这些不确定性可能来自设计参数的选择或系统参数的修改。因此,有必要利用统计方法来测量存在不确定性时VSC谐波失真的程度。一个由三个VSCs组成的实际微电网实验室也被用来实验评估单变量降维(UDR)的性能。蒙特卡罗模拟(MCS)方法作为判断预期UDR结果准确性的标准。在每一个案例中,UDR的预期结果都比MCS采取的方法节省了大量的时间,并且UDR的结果与MCS采取的策略很好地匹配。
