Risk and Vulnerability Management of Electrical Distribution Grids

Johansson, Jonas LU and Svensson, Stefan (2008) Nordic Distribution and Asset Management Conference (NORDAC2008)
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... (More)
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. (Less)
