Modeling of load during and after system faults based on actual field data

Appropriately modeling load characteristics is important for power system analysis, in particular for voltage instability phenomena. Load modeling is becoming ever more important with the increasing penetration of power electronic based loads. In order to improve the process and accuracy of power system planning and to be able to make rational and economical decisions based on studies, appropriate load models for planning studies are critical. Thus, to improve load modeling, a study based on actual field data was carried out and is described in this paper.
