A framework for risk-informed decision support in electricity distribution companies utilizing input from quantitative risk assessment

摘要

Electricity distribution companies are to an increasing extent using risk assessment methods in their asset management practices. This paper presents an overall framework for risk-informed decision support where simplified risk analysis methods are used for initial risk assessment, and quantitative risk analysis methods are used to perform more in-depth studies for selected problems. Quantitative risk assessment methods are far more laborious compared to simplified analyses, so it is important that such analyses are performed only to a limited number of risk problems.
