On undervoltage load shedding in power systems

This paper presents an analytical basis and criterion for undervoltage load shedding in power systems. If the voltage is unstable, the proposed undervoltage load shedding criterion can be used to calculate the amount of load which must be shed to stabilise the voltage magnitude. By using a dynamic load model it has been possible to form the criterion which gives the amount of load which has to be shed to stabilise the system in each point in time. The criterion is general and can be applied to any power system. Copyright © 1996 Elsevier Science Ltd.link_to_subscribed_fulltex
