Recently, due to the progress in the development of wind generators and solar panels, autonomous hybrid energy systems based on renewable energy sources, which include solar panels, wind generators and power units, have been used for reliable power supply to remote settlements. The vulnerability of a hybrid power plant is its dependence on external climatic conditions and power units require fuel. To solve this problem, it is proposed to supplement hybrid systems with the use of power systems based on the day-night temperature difference. Today, there are no developed circuit solutions for the structure of a hybrid electrical complex based on renewable energy sources with a system of daily temperature difference in its composition according to a scheme with a common AC bus. (Research purpose) The research purpose is developing electric circuits of an autonomous hybrid power plant based on renewable energy sources with a temperature change system taking into account the load and determining the turn-on time of the gasoline generator. (Materials and methods) Considered an electrical complex of hybrid type with four sources of electrical energy, which includes a system of daily temperature difference. (Results and discussion) We have developed schemes for an autonomous hybrid electrical complex based on renewable energy sources with a temperature change system and an alternating current bus for power supply to remote agricultural facilities. The problems of the complex when using several inverters operating on one AC bus in the circuit and ways to solve them were shown. We calculated the loads for each power system and deduced the condition for switching on the gasoline power unit in adverse weather conditions. (Conclusions) It was determined that the developed electrical circuits with a load control unit and a common master generator of a hybrid energy system based on renewable energy sources with a temperature difference power system allow creating an optimal mode of its operation and managing the entire hybrid system more efficiently.
