To evaluate the intelligence level of grid in our country scientifically, an evaluation index system of grid’s intelligence level is presented. There are two parts of the index system, i.e. construction effect and construction basis. Based on the promotion and the guidance between effect and basis, an interaction is created by matching basis and effect indexes. To embody the interaction and to enhance the accuracy of consequence, a tentative evaluation procedure and method specific to the above index system is proposed, in which the analytic hierarchy process, entropy method and grey correlation analysis are used. Results of applying the proposed method in practical case show scientificalness and effectiveness of the proposed index system. The correlation degree between effect and basis can be calculated. It’s conducive to the discovery of weaknesses, and construction direction of grid’s intelligence can be brought.
