An important tool for the energy management system (EMS) is state estimation. Based on measurements taken throughout the\r\nnetwork, state estimation gives an estimation of the state variables of the power system while checking that these estimates are\r\nconsistent with the measurements. Currently, in the Cameroon power system, state estimates have been provided by ad hoc\r\nsupervisory control and data acquisition (SCADA) systems. A disadvantage is that the measurements are not synchronised,\r\nwhich means that state estimation is not very precise during dynamic phenomena in the network. In this paper, real-time phasor\r\nmeasurement units (PMUs) that provide synchronised phasor measurements are proposed for integration into the power system.\r\nThis approach addresses two important issues associated with the power system state estimation, namely, that of measurement\r\naccuracy and that of optimization of the number of measurement sites, their location, and the importance given to their\r\nmeasurements on the dynamic state estimation.
