openmodelica-microgrid-gym 0.2.0

Installation

Getting started

The environment is initialized and run like any other OpenAI Gym

import gym

if __name__ == '__main__':
    env = gym.make('openmodelica_microgrid_gym:ModelicaEnv-v1',
                   model_input=['i1p1', 'i1p2', 'i1p3'],
                   model_output=dict(lc1=['inductor1.i', 'inductor2.i', 'inductor3.i']),
                   model_path='grid.network.fmu')

    env.reset()
    for _ in range(1000):
        env.render()
        env.step(env.action_space.sample())  # pick three continous control actions randomly
    env.close()

OMG uses the FMI standard for the exchange of the model between OpenModelica and Python.

An example network consisting out of two inverters, three filters and an inductive load.

You can either use one of the provided FMUs (Windows and Linux, 64-bit, both included in the grid.network.fmu) or create your own by running:

openmodelica_microgrid_gym\fmu> omc create_fmu.mos

Running the staticctrl.py starts a simulation with a manually tuned cascaded PIPI controller

A save Bayesian approach of a reinforcement learning agent is provided under examples/berkamkamp.py.
