Study and analysis of the stochastic harmonic distortion caused by multiple converters in the power system (micro-grid)
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.
