The mosaik protocol handler can be used to access data from the Smart Grid co-simulation framework mosaik.
To connect odysseus and mosaik, the odysseus query has to run first and after that the simulation in mosaik can be started.
In the mosaik documentation a tutorial can be found which describes the connection between mosaik and odysseus.
Options
- cleanStrings If set to true, all underscores (_) in attribute names are replaced by hyphen (-), so that they can be used in expressions.
Example
PQL
MosaikProtocolHandler
mosaik = ACCESS({TRANSPORT = 'TCPServer',
PROTOCOL='Mosaik',
SOURCE = 'Mosaik',
DATAHANDLER = 'KeyValueObject',
WRAPPER = 'GenericPush',
OPTIONS =[
['port', '5555'],
['mosaikPort', '5554'],
['byteorder', 'LITTLE_ENDIAN']
]})
///short version:
mosaikInput = MOSAIK({source = 'MosaikReceiver',
type = 'simapi'})
/// type = 'zeromq'})
Simulator in mosaik
To allow the connection in mosaik a simulator has to be created as follows:
Initialising mosaik simulator
sim_config = {’Odysseus’:
{’connect’: ’127.0.0.1:5554’ }
}
odysseusModel = world.start(’Odysseus’, step_size=60*15)
odysseus = odysseusModel.Odysseus.create(1)
To receive data components have to be connected to the simulator in the mosaik scenario definition.
In the mosaik-demo this could be:
Connecting mosaik simulator
connect_many_to_one(world, nodes, odysseus[0], 'P', 'Vm') connect_many_to_one(world, houses, odysseus[0], 'P_out') connect_many_to_one(world, pvs, odysseus[0], 'P')
More details can be found in the mosaik documentation.
