Resources

There are seven basic resource types. This includes shed demand response and flexible loads, which are modeled as resources (instead of as loads).

In Recap, resources are grouped into 7 different types. Each of these resources have their own inputs, assumptions, and constraints. Future work includes making Recap a mulit-zonal model. Challenges include how resources would heuristically dispatch and tuning perfect capacity across multiple zones.

Resource	Type	Heuristic Dispatch	Optimized Dispatch
Generic	Availability	Yes	No
Variable	Availability	Yes	No
Hydro	Energy-Limited Resource	Yes	Yes
Storage	Energy-Limited Resource	Yes	Yes
Hybrid	Energy-Limited Resource	Yes	Yes
Shed Demand Response	Energy-Limited Resource	Yes	Yes
Flexible Loads	Energy-Limited Resource	Yes	Yes

Each resource class as their own set of constraints and therefore their own set of constraints. Below is a list of Attributes for all resource classes
