10 months ago regarding "has_global_default" in the table above
global defaults are values which are equal for all source regions.
I checked for the combinations where a global default should be present from the above table. Global defaults are queried with empty strings in source_region_code. The following code works with 4032cb84256fc4b0f0c0e26cb4eeecd774973a08 on the api-data branch:
from ptxboa.api_data import DataHandler
from ptxboa.api import PtxboaAPI
api = PtxboaAPI()
handler = DataHandler(api.data, "2030 (high)")
for process in api.data.dimensions["process"]["process_code"].to_list():
for parameter_code in ["CAPEX", "OPEX-F", "SPECCOST", "WACC"]:
try:
value = handler.get_parameter_value(parameter_code, process_code=process, source_region_code="")
print(f"found global default for {process}, {parameter_code}: {value}")
except ValueError:
print(f"No global default for {process}, {parameter_code}")Looking at the output , we see that for many parameter / process combinations, there exists no global default. Is this intentional @wingechr & @markushal?

10 months ago For the following parameter we only use region specific data, and global defaults are not needed:
For all other parameters region specific data does not exist (as long as it is not defined by the user), so there should be a global default value, and there should be no region specific data points in the input data set.
@joAschauer I tried to write down my thoughts on the general structure of the
api.calculate()function in a class based design:a
chainis a series of main processes (and optionally attached secondary processes)each process is an instance of a (sub) class of class
processmain subclasses are (probably):
each process has a main
flowthat converts an input value to an output valuethis conversion creates also values for required secondary flows
we probably want a function
set_input_flow(self, value)to set the input that triggers these calculationsmost of the calculation requires process specific
parametersparametersare also dependent on user selections likewhenever a process instanciated, depending on it's subclass, it has to retrieve it's parameters from the data api, e.g. parameter EFF (efficiency):
or for instance conversion parameter for secondary flows:
maybe we also want classes for
flows, but also maybe not, there is not really any logic attached to it,so maybe just using the code strings is enoughList of Parameters
List of Processes
List of Flows
