Nowadays, information construction has become very common, and modern rural areas are one of them. Power supply enterprises play a very important role in the construction of modern rural areas, and people's lives are inseparable from power support, so they need to be cautious in the selection of power grid demonstration areas. The ordinary selection method cannot solve the problem of selecting modern rural power grid demonstration areas among power supply enterprises. Therefore, this paper proposes an AHP algorithm to carry out the selection and analysis of modern rural power grid demonstration areas. Firstly, the hierarchical analysis is used to evaluate the power grid demonstration area, and the indicators are divided according to the selection requirements of the modern rural power grid demonstration area to reduce it Interference factors in the selection of modern rural power grid demonstration areas. Then, the hierarchy analysis analyzes the selection results of the modern rural power grid demonstration area of power supply enterprises, forms the selection plan of the modern rural power grid demonstration area, and selects the modern rural power grid demonstration area The results were comprehensively analyzed. MATLAB simulation shows that under the condition of certain evaluation criteria, the AHP algorithm selects the modern rural power grid demonstration area of power supply enterprises The feasibility and rationality of the selection of modern rural power grid demonstration areas are better than ordinary selection methods.
