Resumen:

A comparative study of three methodologies for estimating transmission lines parameters together with nodal voltage state variables at system level is presented in this paper. The estimation process to determine both conventional system variables and parameters of some transmission lines is simultaneously performed by using the weighted least squares (WLS) formulation. The parameters to be determined are series impedance and shunt admittance of the associated \pimodel of transmission lines. In this context, the type of parameters included in WLS-based formulation as state variables is what differentiates the methodologies considered. Numerical results are presented using the IEEE 14-bus test system and show that the methodology employing the lowest number of state variables performs extremely well even though the number of transmission lines parameters to be estimated increases. © 2019 IEEE.
