HOMER Grid models the cost of an outage to the customer and the cost to keep only critical loads running during an outage event.
Resilience: Resilience refers to multi-day outage events that occurs at a maximum of once per year. This is used to model natural disasters like a hurricane, flood, or fire.
Reliability: Reliability models multiple short outages that occur every year.
Outage Settings: This section also gives you additional ways to control your system during the outage. For example, you can ensure your generator runs only during an outage or you can add a penalty for every hour there is a capacity shortage.
Non-Critical Load: In case of an outage or a demand response event, only the critical load will be served. The Electric Load is the critical load. During normal grid operation, the sum of the Electric Load and the Non-critical load is served. For example, the owner of a super market would like to keep at least the freezer/refrigerator running during an outage to minimize loss to their business.
