Abstract

An approach to evaluate the HVDC interconnectionsmodels to be used in real-time voltage stability assessment is proposed.The existing models for the HVDC interconnections, thatare based on voltage source converter, were studied selecting theones that are suitable for its application in Thevenin equivalent ´methods for voltage stability assessment. The proposed methodis to evaluate the validity of the models by using synthetizedPMU measurements from simulations and from PMUs connectedto the danish system. Wide-area measurements are used toestimate the HVDC model parameters which are needed tocalculate a distance to the instability boundary. The parametersare benchmarked according to their expected uncertainty andits impact in the Thevenin equivalent methods is evaluated. The ´results show the used pre-processing procedure for the real PMUmeasurements and simple criterion for the evaluation of theparameter validity. The parameters calculated for all the selectedmodels are between the expected uncertainty values for a timewindow of at least 2 cycles.
