The research objective is to solve the robustness problems suffered by the existing state estimators, i.e., no convergence warranty and weakness in detecting multiple bad data, especially topology errors. The invention consists of a new formulation of state estimator and an efficient solving process. The novelty of the research is in bringing together cutting-edge ideas from diverse disciplines including graph theory, linear algebra, matrix theory and high dimensional statistics, to solve the robustness problem of current state estimators. The anticipated technical results include comprehensive testing on different power systems including real systems, and a commercialization plan of the patented technology.
