On influence of load modeling for undervoltage load shedding studies

This paper explores the influence of load models on decisions of undervoltage load shedding in power systems. A controlled load rejection can he used as an emergency countermeasure to avoid widespread blackout when system voltages are unstable. In this paper, dynamic simulations of a small power system using both static and dynamic load models are presented. When using a static load model, the system includes an explicit model of a transformer with load tap changer. The aim is to demonstrate how different load models influence the analysis and calculation of the amount of load needed to be shed to stabilize the system voltage.link_to_subscribed_fulltex
