A new approach for including synchronized phasor measurements in dynamic state estimation

Synchronized phasor measurements, are useful devices for monitoring the performance of the power systems for improve the Energy Management System (EMS) applications at the control center. This paper presents a new alternative approach for using the PMU in Dynamic State Estimation. Where, the rectangular coordinate of the current is decoupled and added to decoupled formulation of the Weighted Least Squares (WLS) state estimation. The proposed approach is applied to the standard IEEE 14-bus system as the case study. MATLAB program software is used to realize the simulation process thus verifying the excellent performance of the proposed approach.
