Abstract
State estimation is an useful tool that helps in monitoring of a power system. With changes occurring constantly in the system, a real time estimation is of utmost importance. It is an important tool for modern control center operation in the smart grid. With the implementation of synchrophasor technology, efficient and real-time state estimation has become simpler. PMUs are not connected to all the buses of the network and so real time estimation is required to know the status of those buses. In this paper, real time simulation of two systems, viz., WSCC 9-bus system and IEEE 39-bus system, have been performed using ePHASORsim, a power system simulator that uses phasor data.
