The article analyzes the pace of increase in the generation of photovoltaic stations in the context of the combined electricity system of Ukraine and the energy supply company of PJSC "Vinnytsyaoblenergo". An analysis of existing regulatory documents regulating the work of photovoltaic stations has been carried out. Within the framework of the considered documents, the criteria for assessing the reliability of the operation of electric networks, namely, the length of long breaks in electric power supply of consumers of electric energy SAIDI are defined. The interconnection of the change of reliability indices of electric networks operation with the increase in the number and installed capacity of renewable energy sources, in particular photovoltaic stations (PV), is shown. In order to increase the reliability of power supply, a method of its renewal has been proposed, due to the joint use of generation of small hydroelectric power stations and PV stations. Streszczenie. W artykule analizowano kombinowany system energetyczny na Ukrainie zawierający ogniwa fotowoltaiczne. Na podstawie dokumentacji analizowano niezawodność systemu biorąc pod uwagę przerswy w dostawie energii. Zaproponowano poprawę przez dołączenie małych elektrowni wodnych. Wpływ rozproszonych źródeł energii na niezawodność sieci elektrycznej
