Abstract :
A state estimation tool is presented which is suitable for distribution system real time monitoring. The tool is considered to be a critical component of a smart grid infrastructure that will enable modernization of the distribution grid. The proposed estimator is advantageous compared to currently available estimators for two reasons. First, it is based on a three phase physical model of the distribution system. Moreover, it utilizes synchronized measurements available from a novel proposed device (UGPSSM). The synchronized measurement set combined with conventional non-synchronized measurements from SCADA systems results in improved solution and convergence speed. Reporting and visualization tools are also developed in order to make it a user friendly tool for the operators in the DMS. The state estimator provides the operator with a highly accurate real time model of the distribution system that can be used in various applications including Volt/Var control, load levelization and reliability enhancement.
