Abstract
Risk and vulnerability management can serve a very important purpose as a decision support
tool for investments and planning of electrical distribution systems. In 2006 amendments to
the Swedish Electricity Act came into force, stating that every distribution system operator
has to, on a yearly basis, perform a risk and vulnerability analysis regarding security of supply
to customers. Furthermore, the act also declares that risk mitigating efforts should be
addressed and reported to the enforcing authority, i.e. encompassing a risk and vulnerability
management approach. The present paper will discuss the concept of risk and vulnerability
management for electrical distribution systems and how it interplays with other regulatory
frameworks. Similarities and differences between the concepts of risk and vulnerability, as
proposed by the authors, are also discussed. The paper covers both how such an analysis can
be performed, using consumer and network structure information combined with network
operational and performance data, and how the results can be incorporated and utilised in the
overall management of electrical distribution systems. Important issues that require further
research and input from stakeholders are also illuminated. Such issues are for example how to
define appropriate risk acceptance criteria and the impact of the regulatory framework
concerning quality of supply for distribution system operators.
