This paper describes the development of robust processor for analyzing network state in Korean Energy Management System. The important function of topology processing is to convert the switching/device model into a bus/branch model by the status of switching devices. The state estimator also provides a consistent unified solution, not only for measurement of the observable system, but also for the unobservable system. The primary function of the online power flow is to provide a highly reliable and flexible power flow solution that can be used to solve a wide variety of power systems problems. The validity of the newly developed functions has been verified through comparative simulations with the existing EMS functions, which are currently in use in the Korean power system.
