Abstract :
Mixture data obtained from billing information have been used with the LOADSYN program to develop dynamic load models for large-scale studies. The impact of dynamic load modeling is studied under different scenarios using an Ontario Hydro 4000-bus basecase. The sensitivity of the results to the extent of dynamic modeling is assessed by using up to 449 dynamic models. The field measurements of a tornado event are used to weigh the accuracy improvement offered by dynamic models against their extra computation burden.<>
