Bus-Branch Transmission Modeling

Creating a BusBranchModel

Import all required libraries for data profile, connection parameters, database, and BusBranchModel:

import cimgraph.data_profile.rc4_2021 as cim
from cimgraph import ConnectionParameters
from cimgraph.databases.blazegraph import BlazegraphConnection
from cimgraph.models import BusBranchModel

# Blazegraph Connection
params = ConnectionParameters(url = "http://localhost:8889/bigdata/namespace/kb/sparql",
                              cim_profile='rc4_2021', iec61970_301=8)
blazegraph = BlazegraphConnection(params)

Create CIM EquipmentContainer object:

model_mrid = "1783D2A8-1204-4781-A0B4-7A73A2FA6038" #IEEE 118 Bus
container = cim.ConnectivityNodeContainer(mRID=model_mrid)

network = BusBranchModel(connection=blazegraph, container=container, distributed=False)

network.get_all_edges(cim.ACLineSegment)
network.pprint(cim.ACLineSegment)

cim_profile = 'cimhub_2023'
cim = importlib.import_module('cimgraph.data_profile.' + cim_profile)

# RDFLib File Reader Connection
params = ConnectionParameters(filename="../cimgraph/tests/test_models/IEEE118_CIM.xml", cim_profile='cimhub_2023', iec61970_301=8)
rdf = RDFlibConnection(params)

model_mrid = "1783D2A8-1204-4781-A0B4-7A73A2FA6038" #IEEE 118 Bus"
container = cim.ConnectivityNodeContainer(mRID = model_mrid)
network = BusBranchModel(connection=rdf, container=container, distributed=False)
