ПРО ДОСЛІДЖЕННЯ ОДНІЄЇ MICROGRID

The main part of the work focuses on the analysis of the existing Microgrid, where the traditional backup diesel power plant (DPS) was gradually supplemented by a system of photovoltaic panels, energy storage and a hybrid inverter. The calculations of economic efficiency, expressed in terms of the integral effect (NPV), allow us to determine the payback periods of various Microgrid organization options - from operation only with DPS to combined schemes using storage. It was found that optimization of operating modes (including through modernization of storage) can reduce the payback period, which significantly increases the attractiveness of investments in such projects. The article focuses on the analysis of the impact of tariff formation and market conditions on the economic indicators of projects, since real prices for electricity and fuel significantly affect the financial feasibility of implementing a Microgrid. The article not only demonstrates the relevance of the use of Microgrids to ensure stable and efficient electricity supply in the face of modern challenges, but also offers specific methodological approaches to optimizing their operation from an economic and energy point of view. This study creates a basis for further developments in the field of integration of renewable energy sources and optimization of operating modes of power systems in Ukraine.
