Electricity Distribution Resilience Framework Through West Coast Alpine Fault Secenario

Abstract

The poster gives an overview of the research for the funded project " Electricity Distribution Resilience Framework through West Coast Alpine Fault Scenario". This research is being undertaken through four tracks: quantification of disaster impacts, micro-grid solution to boost electricity distribution network resilience, power system optimum recovery from disasters and communication lifeline resilience and its inter-dependency to electricity.

The first track aims to provided quantitative estimate on the likelihood of different levels of damage and extent of affected areas under different earthquake intensities, which is worthwhile for determining the necessary upgrading of an existing system and for emergency planning and disaster reduction preparedness, including restoration of power.

Widespread sustained blackouts is highly likely to happen after an AF8 earthquake. Microgrid is a potential possibility to bring power back up within the shortest possible time frame. In collaboration with West Coast distribution system operator, the feasibility of forming microgrids on West Coast after a major earthquake is being investigated from technical perspective.

Optimum distribution network restoration for Westpower network is also being undertaken. The generator’s black start capability with all available network components are examined after which critical assets required for this activity are mapped.

Communication is integral for infrastructure resilience. The mechanisms by which communication networks are affected following large-scale natural disasters are studied. This research track will investigate the extent to which wireless systems can be dynamically reconfigured to provide coverage to ‘cutoff’ regions, while still maintaining acceptable levels of interference and quality of service
