4 - Add Network Technology Candidates

Network Technology Candidates and Network Link Candidates are used to specify the possible installation of network infrastructure for transfer of energy carriers between different hubs. Key features include:
A link candidate can be specified between any 2 hubs.
Multiple link candidates, e.g. corresponding to different energy carriers, can be specified between 2 hubs.
For each Link Candidate, a corresponding Network Technology needs to be defined, which specifies the technical and economic parameters of the link.
Similar to conversion and storage technologies, network technology candidates can be added from a database (Add from Database) or created from scratch (Create Custom)

|
Cost parameters |
|
|
|
|
Lifetime | years | Yes |
| The financial lifetime of the technology; specified in years. This is used as a basis for annualizing the investment costs of the technology. |
Fixed Investment cost | CHF/m |
| 0 | The fixed investment costs of the technology per meter (not annualized), incurred in the specified amount if the technology is installed, regardless of the sizing. |
Variable Investment Cost | CHF/kW/m |
| 0 | The variable investment costs of the technology (per kW and meter of installed capacity, not annualized) |
Fixed O&M Cost | CHF/m/year or |
| 0 | The operation and maintenance costs of the technology per meter that are incurred as a fixed amount each year if the technology is installed |
Variable O&M Cost | CHF/kW/m/year |
| 0 | The operation and maintenance costs of the technology (per kW per meter of installed capacity) that are incurred as variable amount each year depending on the installed capacity. |

|
|
Environmental parameters |
|
|
|
|
Fixed Embodied CO2 | kg-CO2/m |
| 0 | The embodied CO2 of the technology (i.e. the CO2 emissions incurred in the course of the technology's production and installation) |
Variable Embodied CO2 | kg-CO2/kW/m |
| 0 | The embodied CO2 of the technology (i.e. the CO2 emissions incurred in the course of the technology's production and installation); expressed per kW per meter of installed capacity |
Explanation of Network Link parameters
PARAMETER | UNITS | REQUIRED? | DEFAULT | EXPLANATION |
Optimization Options |
|
|
|
|
This Network Link must be installed |
|
| FALSE | The hubs in which the technology is forced to be installed |
|
|
|
|
|
Technical parameters |
|
|
|
|
Technology Capacity | Optimize / Specify Capacity |
| Optimize | Select whether to Optimize the capacity or specify the capacity manually (Specify Capacity) |
Capacity | kW | Yes, if "Specify Capacity" is selected above |
| The pre-specified capacity of the technology; only visible if Specify Capacity is selected above. A non-zero value of this parameter does not force the installation of the technology. Rather, it only specifies that, if the technology is installed, this is the capacity which it must assume. |
Node 1 |
| Yes |
| The hub which constitutes one of the extremes of the link. |
Node 2 |
| Yes |
| The other hub which constitutes the other extreme of the link. |
Network Technology |
| Yes |
| The network technology which can be potentially installed in this link geometry |
Length | m | Yes |
| Total length in meters of the network link |
Uni-Directional Flow? |
| Yes | No | Whether 2 directions or just 1 can be chosen by the optimization for this link. The Sympheny engine will choose whether 1 à 2 OR 2 à 1 is the optimal direction of the energy flow |
