Abstract :
This paper presents a method for detailed representation of substations in power system state estimation. The conventional weighted least squares state estimator is extended by incorporating the active and reactive power flows of circuit breakers as state variables. Power system observability and state estimates are determined based on a reduced model. The method is illustrated with a 12 bus system.
