This article discusses the development of a system for the combined use of solar and water energy based on a systematic approach to power supply. An improved physical model has been developed based on a model for predicting the production of electricity, taking into account the power and time of solar radiation, the amount and speed of water flow. At the same time, the share of electricity in the use of solar and water energy was determined simultaneously, depending on the conditions for the uninterrupted supply of consumers with the daily necessary electricity. The assessment of indicators of the combined use of solar and water energy and the definition of energy efficiency were developed by the authors on the basis of an increase in the share of electricity obtained from renewable energy sources in the electricity supply, which is explained by the coincidence of theoretical and experimental results.

“…The high cost of electric generators operating at low rotation speeds does not allow the use of such low-frequency hydraulic turbines on a large scale. Therefore, in order to increase the coefficient of water energy use, counter-rotor hydraulic units were created in the works [1,2,3,4]. These hydraulic units are equipped with two successive impellers located in one vertical pipe, and the water entering the first impeller from the first guide vane rotates it, and through the following guide vanes enters the second impeller and causes it to rotate.…”

In the field of hydropower, which is one of the sources of renewable energy, there are many places where water pressure of 2-5 meters can be created in water sources. However, hydraulic turbines operating on such sources are not widely used due to insufficient efficiency. This paper describes a counter-rotor hydraulic unit developed by installing an additional active impeller to a reaction hydraulic turbine based on a Segner wheel. Based on experimental results and theoretical analysis, the energy efficiency of a counter-rotor hydraulic unit was studied. As a result of research, it was found that the efficiency of a counter-rotor hydraulic unit varies between 87.2-93.5% at a water pressure of 2-5 meters.

“…One of the most important challenges in the world today is related to sustainable energy production, reducing the use of fossil fuels and preventing the increase in pollution and carbon dioxide emissions. Therefore, researchers are encouraged to conduct research on the use of clean and renewable alternative energy sources such as hydro, solar, wind and geothermal energy [1][2][3][4][5][6][7][8]. The use of water energy has been one of the most important sources of electricity generation for several hundred years, first it was used to obtain mechanical energy for mills, and then to generate electricity [9,10].…”

This article considers the main methods of regulating water consumption and power of micro hydroelectric power plants. New technical solutions for screw jet turbines adapted to low pressures and water flow rates are proposed. The Archimede’s screw turbine is a cost-effective and environmentally friendly microhydropower technology that operates at high efficiency at low pressure and medium flow rates. In this case, the change in power depends on the following parameters: the number of blades, water flow, the angle of inclination of the blades and the height of the pressure. Preliminary calculations carried out by the authors show that the power of a microhydroelectric power station depends on individual factors of the area. With an increase in the speed of the water flow, the speed of the water wheel also increases, and in turn, the electric power of the microhydroelectric power station increases.
