  • Currently, in Vietnam electricity market, hydropower plants still account for a large proportion approximately 38%. Thus, study on control problems of the hydropower plants plays an extremely important role. Load – frequency control is one of the most significant control problems. Major objectives of such a control strategy are to focus on maintaining the system frequency at a nominal value (50Hz in Vietnam) and the tie-line power interchange at a scheduled value.

  • This paper points out the deficiency in the current harmonic frequency estimation algorithm in power system. In order to improve the accuracy of detection and reduce the computational complexity, the study combined the ESPRIT algorithm with multistage Wiener filter (MSWF) recurrence to achieve fast estimation of harmonic frequency.
