Summary, in English

Quality of supply regulations are today in use in a large number of countries. While these regu-lations are likely to decrease the direct economical consequences from power outages it is less clear to what extent they take into account the societal criticality of consumers. In order to advance knowledge in this area, two different ways of estimating consequences of power outages are here contrasted. In recent years a system, named Styrel, has been introduced in Sweden, intended to enable prioritization of critical power customers from a societal perspective during times of power shortage. The Styrel prioritizations are here used as a proxy for the societal consequences of power outages. The second way of measuring consequences that arise makes use of the Swedish power outage regulation concerning outage compensations to customers. A case study is carried out for a real-life distribution system in Sweden, where failures of different sizes are simulated and the two consequence measures are calculated for each failure scenario. The overall result is that the present power outage regulation poorly mirrors the societal consequences as estimated by the Styrel prioritizations, leading to the conclusion that present day power outage regulation in Sweden is not satisfactorily taking some aspects of societal criticality into account.
