photovoltaic panels

The main goal of the work was the measurement of photovoltaic panels on a family house in the village of Lucka in eastern Slovakia during 4 months. The panels were mounted on the south side of the building at a slope of 26 degrees. The measurement took place every day only during sunshine. Subsequently, the comparison of these actually measured values with the calculated values from the PVGIS software, which also serves to calculate photovoltaic panels. Photovoltaic panels were measured in the months of April, May, June, July in 2021.

The paper presents the study results on renewable energy hybrid system within a micro grid which is tied to bulk power system. The voltage variations character has been analyzed considering mode of wind generator reactive power control. Optimal reactive power control requirements are shown in consideration of voltage variation mitigation.
