| description | This paper proposes an assessment framework for branch parameter estimation of power systems, based on which the estima- tion accuracy can be improved and the estimation reliability can be ensured. The proposed framework comprises three parts： 1） Parameter credibility assessment to evaluate the credibility of original parameters in the case that their true values are unknown 2） estimation accuracy assessment to provide quantitative information about the validity of the estimation; 3） parameter domi- nance assessment to find out the key parameters for the estimation. This framework can be incorporated into the conventional parameter estimation process easily such that the accuracy and reliability of the estimation are improved. The implementation problems are addressed in details. Tests are carried out on the IEEE 14-bus system, IEEE 30-bus system, and IEEE 300-bus system to show the correctness and effectiveness of the proposed assessment framework. |
