Mosaik

Mosaik is a simulation compositor for Smart Grid simulations.

It lets you re-use existing simulators and couple them to simulate large-scale Smart Grid scenarios. Mosaik offers powerful mechanisms to specify and compose these scenarios.

Example

A simple demo scenario with mosaik:

>>> import mosaik
>>> sim_config = {
...   'ExampleSim': {'python': 'example_sim.mosaik:ExampleSim'},
... }
>>> def create_scenario(world):
...   sim_1 = world.start('ExampleSim')
...   sim_2 = world.start('ExampleSim')
...   a_set = [sim_1.A(init_val=0) for i in range(3)]
...   b_set = sim_2.B.create(2, init_val=0)
...   for i, j in zip(a_set, b_set):
...     world.connect(i, j, ('val_out', 'val_in'))
...
>>> world = mosaik.World(sim_config)
>>> create_scenario(world)

Installation

Mosaik requires Python >= 3.8. Use pip to install it, preferably into a virtualenv:

$ pip install mosaik
