Resilience Assessment of Islanded Renewable Energy Microgrids
Abstract
The militarys installations on remote islands have the highest power costs and demand resilient and reliable power for mission assurance. These installations have no electrical connection to an external utility provider and encounter numerous challenges in incorporating renewable energy, and there is a pronounced gap in both defining resilience and measuring it for off-grid islanded microgrids at islanded naval installations (INIs). This works research objective was to develop a methodology to choose renewable energy microgrid designs that maximize resilience and minimize costs on remote islands with applications for INIs. The deliverable is a tool that incorporates the methodology to identify the cost of resilience using a measure that captures the area under the resilience curve. The tool uses the models developed in this research to create the resilience and cost trade-off curves for different microgrid design and maintenance options to enable decision makers to choose an optimal microgrid design primarily for remote islanded military installations like San Nicolas Island. The research concluded that resilience can be improved by using optimal power capacity ratios for a renewable energy microgrids, that redundancy improves resilience for less costs, and that more maintenance only improves resilience when the generation capacity is closer to the demand and for microgrids with less redundancy.
