“…Pinto et al [16] presented results of a PQ analysis for a PV system connected to an LV rural network; the voltage at the PCC increased and remained very close to the allowable limit. Similarly, Grycan et al [18] reported that an increase in the PV power injection from a solar farm caused an increase in Vrms at the PCC and a decrease in voltage distortion.…”

“…Table 1 lists some of these studies; several of them include THD/IHD analysis through on-site measurements during several time periods. PV system integration in low-voltage (LV) and medium-voltage (MV) networks can increase the Vrms and decrease the THDV at the PCC [9][10][11][16][17][18][19]21]; this effect seems to be more noticeable for higher PV power injections.…”

“…Moreover, some research has shown that the THDI and IHDI are significant for a low PV power injection but decrease with a higher PV power injection [10][11][12][13][14][15][17][18][19][20]. Nemes et al [14] studied the effect of a 3 kWp PV system in an LV network from the comparison of PQ parameters of a grid using the limits of the IEEE 519, IEC 61000, and EN 50160 standards.…”

“…These studies can be tackled by different approaches. Some authors compared specific PQ parameters with limits or ranges established by standards [10,11,14,18]; other authors classified the data and compared them according to PV injection levels [13,19]; and some other authors compared the parameters for scenarios with and without injection to find the average, maximum, or minimum values [9,[15][16][17]20].…”

The intermittent injection of power and the nature of power electronic devices used for photovoltaic (PV) systems can affect the power quality (PQ) of the grid to which they are connected. This study proposes to quantify and evaluate the impact of PV injection on the PQ of a low-voltage (LV) network by applying a statistical analysis through hypothesis testing for the mean comparison of populations of parameters with and without a PV system. The effects of PV power injection and load demand at the point of common coupling on PQ are monitored. The methodology includes the selection and monitoring of PQ, the use of a matrix for classification of data with similar load and PV power injection conditions, and the application of the Wilcoxon rank sum test. This methodology was applied to evaluate the impact of a 9.8 kWp PV system on the PQ of an LV network.
