The use of Russia's hydroelectric potential for electricity generation is one of the cleanest and environmentally friendly methods as it does not result in the emission of harmful substances and carbon dioxide into the atmosphere. Moreover, it is a reliable and efficient source of energy as water is a constant source of energy. Hydro turbines are used to convert the energy of water flow into electrical energy, which effectively ensures more reliable and stable production capacity for hydroelectric installations. However, micro-hydroelectric power plants have some drawbacks related to difficulties in ensuring the high quality of produced electricity of autonomous power supply systems. This is due to the fact that the load on the autonomous power supply system can vary not only in magnitude but also in nature, which makes it difficult to maintain a stable level of electricity production. The main goal of the research is to determine the ranges of variation of the output electrical parameters of a non-regulated hydrogenerator operating as part of an inverter-based micro-hydroelectric power station for rural domestic consumers. Additionally, the task is to formulate requirements for the hydrogenerator and power conversion devices in static and dynamic operating modes of the autonomous power supply system. Object: inverter-based micro-hydroelectric power station. Methods: simulation modeling, and programming in Matlab Simulink. Results. A simulation model of an electric power supply system with an inverter microelectric power station was developed. The structure of microelectric power station is proposed, as well as the ranges of voltage changes of the microelectric power station generator are obtained.
