SiModIn

Simulation Model Interface

Interface between simulation models and brightway25.

Getting started

The basic usage of SiModIn will be presented for an Tespy powerplant model from the offical Tespy documentation.

To use the existing SiModIn model, import and instantiate the SimModel class:

from simodin import interface as link
from tespy_example import tespy_model

my_model= tespy_model('powerplant')

Than inititate the model and calculate it.

my_model.init_model()
my_model.calculate_model()

Create the technosphere dictionary and pass the model to an modelInterface instance.

my_model.technosphere

my_interface= link.modelInterface('tespy powerplant',my_model)

For LCA calculation, the needed brightway25 dataset needs to be linked to the technosphere flows:

import bw2data as bd

bd.projects.set_current('bw_meets_tespy')
my_interface.methods=[('ecoinvent-3.11',  'EF v3.1',  'climate change',  'global warming potential (GWP100)')]
ei=bd.Database('ecoinvent-3.11-cutoff')

ei_heat=[act for act in ei if 'heat production, at hard coal industrial furnace 1-10MW' in act['name']
 and 'Europe without Switzerland' in act['location'] ][0]
my_interface.technosphere['heat source'].source=ei_heat

ei_water=[act for act in ei if 'market for tap water' in act['name']
 and 'Europe without Switzerland' in act['location'] ][0]

my_interface.technosphere['cooling water source'].source=ei_water
my_interface.technosphere['cooling water source'].dataset_correction = 0.1 #blowdown rate

After that, the LCA calculation can be executed or the data exported to a brightway25 database:

my_interface.calculate_background_impact()
my_interface.calculate_impact()
code= my_interface.export_to_bw()
