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)
Explanation of Network Technology parameters
Network Technology Name
The name of the technology; can be selected freely
The energy carrier that can be transported with this network
The losses as % of total capacity per meter of network length
The maximum allowable capacity of the technology; only visible if Optimize is selected for "Technology capacity"
The minimum allowable capacity of the technology; only visible if Optimize is selected for "Technology capacity"
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
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
The variable investment costs of the technology (per kW and meter of installed capacity, not annualized)
Fixed O&M Cost
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
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.
Fixed Embodied CO2
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
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
This Network Link must be installed
The hubs in which the technology is forced to be installed
Optimize / Specify Capacity
Select whether to Optimize the capacity or specify the capacity manually (Specify Capacity)
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.
The hub which constitutes one of the extremes of the link.
The other hub which constitutes the other extreme of the link.
The network technology which can be potentially installed in this link geometry
Total length in meters of the network link
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
