Micro-grid Based Power Supply of Remote Consumers Located Away from the Centralized Power Grid

The paper presents some of the results of the research aimed to improve reliability of hybrid power systems power supply for low-power consumers in remote areas. Improved reliability of power supply to the population of remote areas will make a great contribution to social and economic development indicators of the area. The main reason for the low reliability of small electricity consumers in remote areas is high cost required for building the power grid for these areas. Micro-grid is the most efficient power supply system for such areas. The study recommends reducing capacity of storage batteries in hybrid power systems that are based on renewable energy sources and use such energy sources directly at regular intervals. In hybrid power systems, relatively low utilization of energy storage devices or reduced capacity leads to improved economic performance of the system. Expensive energy storage devices, especially in the Republic of Uzbekistan, where electricity prices are low, can reduce the economic performance of hybrid energy systems. However, little use of energy storage devices can adversely affect the power supply reliability. As a result of the research, a device based on Arduino microcontroller was created aimed to control energy flows in a hybrid power system.
