Hybrid photovoltaic systems have become a common solution for decreasing energy consumption for specific objects and customers at present time. The efficiency of the entire system depends strongly also on the technology of the used battery inverter. In general, DC-coupled inverters are recognized to be more energy efficient. Surprisingly, in some specific cases, AC-coupled systems can offer better results. Ukraine escalates the problem with internal migration, that can be solved just through constructing new communities of emergency shelters.

W pracy zaproponowano model matematyczny wyznaczania częstotliwości rezonansowej linii 750 kV względem nieobciążonego
transformatora oraz zbadano możliwość wystąpienia przepięć w liniach 750 kV na 2. harmonicznej. Opracowano obwód rezonansowy do
wyznaczania częstotliwości drgań własnych linii elektroenergetycznej ultrawysokiego napięcia w celu analizy warunków przepięć przy składowych
wyższych harmonicznych. Otrzymuje się wyrażenia analityczne w celu określenia stopnia wpływu wartości parametrów linii na częstotliwość
rezonansową linii. W artykule przedstawiono zależność między trybem pracy linii najwyższych napięć a autotransformatorem (transformatorem) na
warunki występowania przepięć. Podano wyrażenia analityczne do oceny wpływu stopnia kompensacji mocy ładowania na wartości parametrów
modowych elektroenergetycznej linii przesyłowej najwyższych napięć; The paper proposes a mathematical model for determining the resonant frequency of a 750 kV line relative to an unloaded transformer and studies the possibility of overvoltages in 750 kV lines at the 2nd harmonic. A resonant circuit has been compiled to determine the natural frequencies of an ultrahigh voltage power line to analyze the conditions for overvoltages at higher harmonic components. Analytical expressions are obtained to determine the degree of influence of the line parameters` value on the line`s resonant frequency. The paper presents the relationship between the operating mode of an ultra-high voltage power line and an autotransformer (transformer) on the conditions for the existence of overvoltages. Analytical expressions for evaluating the influence of the degree of charging power compensation on the values of the mode parameters of the ultra-high voltage power transmission line are given.

The research deals with the design of an optimal photovoltaic system for a specific location in the Czech Republic. Commercially available different types of PV panels were installed in the ed locations for the collection of data was used Arduino platform. Optimal technical and economic recommendations were developed for the four types. The work was successful in confirming some characteristic features of these types of panels according to theoretical models. In some cases, the effect of the technical performance of the measurement and the behavior of the panel was slightly different.
