Abstract
This manuscript illustrates the measurement results of parameters describing the quality of energy at the PCC (point of common coupling) of a photovoltaic micro-installation that can significantly affect devices in the same power grid. The analyses reflecting heating of selected devices used in domestic installations, which were performed in an isolated laboratory environment, are also indicated. The conducted study aimed at checking the thermal characteristics of the chosen equipment, i.e., AC/DC power supply, LED and fluorescent light sources, a step-down transformer at synergistically higher voltage harmonics and constant component in the network voltage. The tests were carried out at the disturbance levels recorded at the site of the photovoltaic micro-installation. The conducted tests aimed at indicating the presence of an increased level of synergetic disturbances in the vicinity of micro-photovoltaic installations. Based on the research, recommendations were made for photovoltaic micro-installations.
Highlights
Power electronic devices have recently recorded a significant increase in domestic appliances, which is mostly due to the development and wide use of renewable energy installations
The conducted analyses illustrated a relatively high level of disturbances in the voltages measured near the monitored photovoltaic installation
The examined nature of the disturbances suggests that they originated from a working photovoltaic installation, which, for unknown reasons, works incorrectly
Summary
Power electronic devices have recently recorded a significant increase in domestic appliances, which is mostly due to the development and wide use of renewable energy installations. Similar problems have already been monitored in different photovoltaic installations in various parts of the world and presented among others [7,8,9,10] They indicate a number of similarities in the reported problems resulting from incorrect operation of renewable energy systems. There may be miscellaneous damages related to malfunction of devices under the influence of existing disturbances Such effects have been observed in various parts of the world where renewable energy installations have grown rapidly.
