SiModIn

Simulation Model Interface

Interface between simulation models and brightway25.

SiModIn can be used to:

• Create simulation based brightway25 datasets.
• Calculate the impact of your models.
• Provide your simulation models for LCA studies.

Installation

Install SiModIn from PyPi:

pip install simodin

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 SimModel_powerplant import tespy_model
from simodin import interface as link

my_model= tespy_model('powerplant')

Then 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.define_flows()

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

For LCA calculation, the needed brightway25 dataset needs to be assigned 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]

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.add_dataset('heat source', ei_steam)
my_interface.add_dataset('cooling water source', ei_water)
my_model.set_flow_attr('cooling water source', 'dataset_correction', 0.1)

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()
