Abstract: The evaluation of state estimation results is an important strategy of reflecting the quality of the basic model and data of grid.According to the drawbacks of the present acceptance rate index of state estimation,a multi-index comprehensive evaluation method of state estimation is proposed.The various influencing factors of state estimation are considered,and identification and redundancy principles are followed.Then the four typical indexes are selected as examples,and their weights are determined using the analytical hierarchy process（AHP）.Finally,an actual case of power grid shows that the multi-index evaluation method is efficient for accuracy evaluation of state estimation and detection of grid problem.
