Risk investigations in investment planning under consideration of a supply interruption insurance system

This paper presents investigations of an insurance approach against supply interruptions as an enhanced model of monetary valuation of supply interruptions. Results of praxis relevant risk-based investigations for different investment measures for medium voltage systems considering the supply interruption insurance system are presented. Upgrading of the protection system, improvement of restoration strategy and the conversion from radial to open loop system structure are considered. The behaviour of a cable and an overhead line power system is compared. Different parameters such as different observation periods and insurance tariffs are taken into account.
