Add config for NEP2021 and NEP2023 cost data #83

Closed toniseibold closed 1 month ago

toniseibold commented 1 month ago
Adressing https://github.com/PyPSA/pypsa-ariadne/issues/82 This PR adds the config[costs][NEP] which can be set to 2021 or 2023. Note that the following costs are available: Paramter & unit NEP 23 NEP 21
AC overhead (€/MW/km) 1325-1384 736
AC underground (€/MW/km) 4711 3386
AC submarine (€/MW/km) - -
DC overhead (€/MW/km) - 1000
DC underground (€/MW/km) 3300-3800 3250
DC submarine (€/MW/km) - -
DC inverter pair (€/kW) - 600

To convert the cost data to €2020 the following discount rates are used: inflation rate 0.5% (2020), 3.1% (2021), 7.9% (2022) -> ~0.89686*investment_cost_2023

Since there are missing some values from in the NEP2023, the costs from NEP2021 are assumed to hold true for the future.

In modify_prenetwork new costs are assigned to lines and links. Depending on the config[costs][transmission] either overhead line or underground cable are assumed for HVDC connections.

Looks good! I am wondering if we should switch to NEP23 as default for all scenarios, though...
