The task of microgrid is uninterrupted power supply and ensuring an energy balance between the consumed and generated capacities. The peculiarities of the operation of renewable energy systems is the dependence of electricity production on external factors: wind speed and direction, daylight duration, water regime of rivers, etc. The non-stationary mode of operation of generating equipment affects the reliability of power supply and the quality of electrical energy. To eliminate the influence of unsteadiness of electricity production, electric energy storage devices based on rechargeable batteries are used to maintain a balance of capacities in an isolated system during periods of generation shortage. Combining various sources into a single system makes it possible to ensure its stability in various operating modes.
