Abstract

State estimation is the primary tools for Energy Management Systems (EMS). Traditional state estimation data are measured SCADA systems which are rather low precision and do not include voltage angles measurements. This paper reports on the implementation of a state estimation algorithm able to incorporate both SCADA and PMU measurements. The implemented algorithm was validated using two well-known IEEE test systems (IEEE-14 and IEEE-118 buses). Analysis of the results obtained from the different case studies performed, may highlight some advantages of incorporating PMU´s measurements in the power system state estimation.
