Most grids are outdated, both physically and in terms of the control methods they operate. Given the significant growth of end users, the amount of energy they consume, and their impact on the stability of the overall grid, the development of distributed energy resources and the integration of new generation units using renewable energy sources are being encouraged. However, the installation of such nodes introduces changes to the established system of capacity and consumption distribution, which necessitates dynamic load and generation control. This article analyzes various schemes of microgrids, which are separate small nodes of the general power grid in which renewable energy sources are integrated, as well as their methods of influence on maintaining the quality of power supply in the grid. The advantages and disadvantages of these methods allow us to make informed decisions in practice to improve the efficiency of energy transmission in microgrids with integrated renewable energy installations and thus promote the use of solar generation for sustainable energy production. The problem of the fact that most of the photovoltaic installations that were introduced in previous years are grid-dependent, which makes it impossible for them to proactively contribute to grid stabilization in case of emergency conditions. As a result, this can be solved by voltage-generating inverter installations, since even in the event of a grid outage and the microgrid going offline, they can generate their own voltage and maintain power supply to all consumers of this subgrid. This paper presents the results of an analysis of scientific articles on the management of microgrids and generating plants, and proposes a method for managing multiple microgrids to improve the efficiency of the distribution system. These ideas require further research to find an effective method for controlling multiple nodes with different generating units, for further implementation in real distribution systems.
