Inputs

  • resources/costs.csv: The database of cost assumptions for all included technologies for specific years from various sources; e.g. discount rate, lifetime, investment (CAPEX), fixed operation and maintenance (FOM), variable operation and maintenance (VOM), fuel costs, efficiency, carbon-dioxide intensity.

Outputs

  • networks/elec_s{simpl}_{clusters}_ec.nc:

Description

The rule :mod:add_extra_components attaches additional extendable components to the clustered and simplified network. These can be configured in the config.yaml at electricity: extendable_carriers:. It processes networks/elec_s{simpl}_{clusters}.nc to build networks/elec_s{simpl}_{clusters}_ec.nc, which in contrast to the former (depending on the configuration) contain with zero initial capacity

  • StorageUnits of carrier 'H2' and/or 'battery'. If this option is chosen, every bus is given an extendable StorageUnit of the corresponding carrier. The energy and power capacities are linked through a parameter that specifies the energy capacity as maximum hours at full dispatch power and is configured in electricity: max_hours:. This linkage leads to one investment variable per storage unit. The default max_hours lead to long-term hydrogen and short-term battery storage units.

  • Stores of carrier 'H2' and/or 'battery' in combination with Links. If this option is chosen, the script adds extra buses with corresponding carrier where energy Stores are attached and which are connected to the corresponding power buses via two links, one each for charging and discharging. This leads to three investment variables for the energy capacity, charging and discharging capacity of the storage unit.
