The Study Of Distributed Algorithm Based On The Generalized State Estimation

This paper deals with the problem of distributed algorithm based on the generalizedstate estimation. The generalized state estimator includes topology and parameters in theestimation and bad data analysis processes, so it increased the accuracy of data and it canestimate running status of systems more accurately, comparing with the traditional stateestimation. But, because matrix dimension of the generalized state estimation is big andthe structure is complex, it is difficult to satisfied the need of real time, so this articlewill use the distributed algorithm of the generalized state estimation, the state estimationof whole system can be decomposed into the state estimation of several subsystems byusing the auxiliary problem principle. A WSCC system is applied to verify feasibilityand the validity of the approach.
