Resilience of power systems is already a key issue that is getting frequent attention all over the world.It is useful to analyze resilience issues not only for bulk supply, but at all levels including at a customer level.This is because distributed energy resources can play a prominent role in enhancing resilience.Although the literature on planning models, tools and data for bulk supply and distribution systems have expanded in recent years, customer-centric planning, e.

g., for an individual household, is yet to receive adequate attention.Although solar PV and battery storage at a household level have been analyzed, how these resources can be optimally combined, together with grid supply, from a resilience perspective is the focus of this study.The study demonstrates how a conceptual framework can be developed to show the trade-off Ergobar between system costs and resilience including its dimensions such as duration, depth and frequency of service outages.

A planning model is Hose Connection Trim Ring developed that incorporates multiple facets of resilience and individual customer preferences.The model considers power system resilience explicitly as a constraint.The model is implemented for a household level case study in Miami, Florida.The results show there are complex trade-offs among different dimensions of resilience.

The study demonstrates how combined resilience metrics can be formulated and evaluated using the proposed least-cost planning model at a household level to optimize grid supply together with solar, battery storage and diesel generators.The model allows a planner to directly embed a resilience standard to drive the optimal supply mix.These concepts and the modeling construct can also be applied at other levels of planning, including community level and bulk supply system planning.
