Resilience Analysis of Extensive Meshed Distribution Network to Supply Feeder Outages

Abstract

Resilience assessment is also relevant for highly reliable power systems, such as meshed networks. The paper deals with resilience of an urban densemeshed low voltage network to supply feeder outages and subsequent cascading failures. Presented resilience analysis evaluates the amount of preserved load during multiple feeder outages. The simulations account for a timespan of 1 year of network operation with regard to load variations. Based on disturbances simulation results, the weakest elements of the network are identified. To increase resilience, corrective measures are proposed and incorporated into the simulations. Resilience improvements of applied measures are evaluated and discussed.Resilience assessment is also relevant for highly reliable power systems, such as meshed networks.
