Sets¤
Basic Sets¤
END_USES_CATEGORIES¤
Description:
Categories of end-uses (e.g., electricity, heat, mobility).
Type:
Main input set.
Usage:
Used to group and classify end-use demand types.
END_USES_INPUT¤
Description:
Types of end-use demand that are input to the model (e.g., lighting, heating, mobility).
Type:
Main input set.
Usage:
Combined with SECTORS to define end_uses_demand_year and subsequently end_uses_input.
INFRASTRUCTURE¤
Description:
Infrastructure components (e.g., DHN, grids, intermediate conversion technologies).
Type:
Main input set.
Usage:
Represents networks and infrastructure elements for distribution and conversion.
PERIODS¤
Description:
Time periods over which the model is solved.
Type:
Main input set.
Usage:
Defines temporal resolution for parameters (e.g., t_op) and variables (e.g., F_Mult_t).
RESOURCES¤
Description:
Available energy resources (e.g., fuels like wood and fossils, electricity imports).
Type:
Main input set.
Usage:
Used to define resource availability, costs, and emission factors.
SECTORS¤
Description:
Sectors of the energy system (e.g., residential, commercial, industrial).
Type:
Main input set.
Usage:
Used for disaggregating end-use demands (end_uses_demand_year).
STORAGE_TECH¤
Description:
Set of storage technologies.
Type:
Main input set.
Usage:
Used to store and release energy, subject to efficiencies and capacity limits.
Derived Sets¤
END_USES_TYPES¤
Description:
Secondary set of all end-use types, constructed from END_USES_CATEGORIES and END_USES_TYPES_OF_CATEGORY.
Definition:
END_USES_TYPES := setof {i in END_USES_CATEGORIES, j in END_USES_TYPES_OF_CATEGORY[i]} j;
Usage:
Used for balancing and meeting demand.
END_USES_TYPES_OF_CATEGORY¤
Description:
For each end-use category, defines the specific end-use types belonging to it.
Definition:
END_USES_TYPES_OF_CATEGORY {END_USES_CATEGORIES};
Usage:
Supports construction of END_USES_TYPES.
LAYERS¤
Description:
Secondary set representing layers of energy flows.
Definition:
LAYERS := (RESOURCES diff BIOFUELS diff EXPORT) union END_USES_TYPES;
Usage:
Used to balance resources and products in the system.
TECHNOLOGIES¤
Description:
All technologies considered in the model, including end-use technologies, storage, and infrastructure.
Definition:
TECHNOLOGIES := (setof {i in END_USES_TYPES, j in TECHNOLOGIES_OF_END_USES_TYPE[i]} j) union STORAGE_TECH union INFRASTRUCTURE;
Usage:
Central set for technology-related parameters and decision variables.
TECHNOLOGIES_OF_END_USES_CATEGORY¤
Description:
Subset of TECHNOLOGIES by end-use category.
Definition:
TECHNOLOGIES_OF_END_USES_CATEGORY[i] := setof {j in END_USES_TYPES_OF_CATEGORY[i], k in TECHNOLOGIES_OF_END_USES_TYPE[j]} k;
Usage:
Groups technologies based on their corresponding end-use categories.
TECHNOLOGIES_OF_END_USES_TYPE¤
Description:
For each end-use type, defines the set of technologies that convert resources into that end-use.
Definition:
TECHNOLOGIES_OF_END_USES_TYPE {END_USES_TYPES};
Usage:
Defines the conversion layer in the model.
Additional Sets¤
BIOFUELS¤
Description:
Subset of RESOURCES representing imported biofuels.
Definition:
BIOFUELS within RESOURCES;
Type:
Subset of RESOURCES.
Usage:

BOILERS¤
Description:
Set of boiler technologies.
Definition:
BOILERS within TECHNOLOGIES;
Type:
