| description | The invention relates to an intelligent power grid elastic distributed state estimation method based on a trust basis and a medium. The method comprises the following steps: obtaining related information of an intelligent power grid system; establishing a state space model of the smart grid system based on the related information; based on the state space model, establishing an abnormal measurement detection mechanism of a trust basis, and obtaining a detection result of abnormal measurement; based on the detection result, calculating a gain parameter of a distributed state estimator; and constructing a distributed state estimator based on the distributed state estimator gain parameter, and estimating the distributed state trajectory of the smart grid system to obtain a distributed state trajectory estimation value of the smart grid system. Compared with the prior art, detection and compensation of abnormal values are considered, the application requirements of actual industry are better met, and the estimati |
