Electrical Power Systems should be designed in order to minimise the effects of system disturbances. However, in order to mitigate the damage caused by severe and unexpected contingencies, new special control philosophies such as automatic under frequency load shedding (AUFLS) were developed. The aim of the AUFLS process is to preserve most of the system and avoid situations of widespread blackouts. However, the design of this type of process, including the definition of parameters, is generally based on historical observations or previous experiences without a specific methodological basis. Furthermore, good evaluation methods among AUFLS schemes and the comparison among different load control philosophies play a major role in the overall performance of the system. This study aims to provide a general evaluation function that can be applied to different load shedding schemes, even those with different philosophies and operating principles. For the sake of exemplification, a set of AUFLS schemes were evaluated by the proposed metric.
