Power quality monitoring is required to provide an evaluation of the harmonic status of the power system. However, only a few buses can, with acceptable costs, be equipped with measuring devices. As a consequence, lack of information has to be covered by means of suitable harmonic state estimation techniques. A technique recently developed in the time-domain where Kalman filter has been used for this purpose; however, it requires the harmonic sources, the error covariance matrices associated… CONTINUE READING
