Allowing for OCGT, CCGT and CHP plants to be retrofitted to hydrogen
kudos to Daniel Rüdt
If the config
[electricity][H2_retrofit_plants][enable] = true
the model is allowed to retrofit OCGT, CCGT and CHP plants which are built later than[electricity][H2_OCGT_retrofit][year]
.E.g. if the year is set to 2019, in
add_existing_baseyear
the OCGT/CCGT links are copied and added asOCGT H2 retrofitted
/CCGT H2 retrofitted
links. Both link types are extendable withp_nom_max
set to the current installed capacity of OCGT/CCGT.If the optimization is myopic, the same function is used in
add_brownfield
.In
solve_network
additional constraints are set for all OCGT/CCGT and OCGT/CCGT H2 retrofitted links in a way that the sum of installed capacity equals the original OCGT/CCGT installed capacity.Some remarks:
Cluster Test Run (3H Resolution)
Together with PyPSA/pypsa-ariadne#65, the development of installed capacities in Germany is the following. Note that the gas fired power plants that are capable of retrofitting are deleted from a certain year on, but the system does not have to retrofit the total installed capacity all at once (so the installed capacity of hydrogen fired plants can be smaller than the previous installed gas fired capacity).
There is still some installed capacity of OCGT from 2015 which does not qualify for retrofitting.
The CCGT plants are not expanded. All installed capacities are from earlier than 2020. The long lifetime does not push them out of the system by 2045.
For CHPs which fall under the
grouping_years_heat
, existing 2024 CHPs are already retrofitted early on. Code currently allows for reduction of installed capacities becausep_nom_min=0
.Checking the model
p_nom_max
is equal for OCGT and hydrogen retrofitted plantsp_noms
