Abstract: This paper aims at the power supply problem of different types of rural users in rural power supply system. It comprehensively considers factors such as rural load density, power supply radius, load characteristics, distributed energy distribution and other factors, combined with the development of different rural areas, The principles of local consumption, practical networking, and other proposals put forward a power supply model for remote areas in eastern Inner Mongolia. By discussing the two methods of decentralized microgrid power supply and centralized power supply, a specific power supply scheme was derived to enable it to solve the local power supply problem.
