Abstract :
This paper investigates the impact of the PTP (Precision Time Protocol) synchronization method, used to synchronize different Phasor Measurement Units (PMUs), on a state estimation application. As a case of study, the output data of the PMUs, synchronized by means of a software-only implementation of the PTP, have been used to estimate the state of an IEEE 57-bus power system.
