要約(英語): Although it is well known that an adequate dynamic load model in power system is indispensable for stability analyses especially when renewable energies highly penetrate nearby loads, researches on dynamic load model are quite poor even in the beginning of a low-carbon era. The authors have represented an actual dynamic load as parallel of an induction motor (IM), a resistor and a capacitor behind fixed impedance, and identified parameters of the dynamic load model using measured data during and after voltage sags. The results were already reported. Since some improvements on the identification were made, the newest results are reported here. The most important three parameters are identified ; IM ratio is 50%, IM inertia is 0.5 sec., and IM loading is 50% at peak demand when power system stability becomes the worst.
