J. Qui et H. Chen, STABLE AND REALIZABLE MODEL IDENTIFICATION FOR POWER-SYSTEM DYNAMIC EQUIVALENT MODEL, Electric machines and power systems, 21(6), 1993, pp. 711-721
This paper describes a new identification approach for dynamic modelin
g of three-phase power system and proposes methods for systematically
determining the stable and realizable (SAR) model structure. A three-p
hase sample system was used to verify this approach and the results of
simulation have shown that the obtained model can characterize the dy
namics of the actual system accurately.
