Abstract: The evaluation index system of smart grid planning and construction is the carrier to scientifically evaluate the development level and construction effect of smart grid and guide the optimal operation of smart grid. It is also the key factor to promote the development of smart grid. A comprehensive evaluation model based on analytic hierarchy process (AHP) and entropy weight method was put forward for this index system. Subjective weight and objective weight are added into the model to calculate the comprehensive weight, which reduces the error caused by the uneven weight distribution. The linear weighted synthesis method was used for index aggregation. Finally, the construction of a district-level smart grid was taken as the evaluation object to verify the effectiveness of the model.
