Gym-ANM

gym-anm is a framework for designing reinforcement learning (RL) environments that model Active Network Management (ANM) tasks in electricity distribution networks. It is built on top of the Gymnasium toolkit.

The gym-anm framework was designed with one goal in mind: bridge the gap between research in RL and in the management of power systems. We attempt to do this by providing RL researchers with an easy-to-work-with library of environments that model decision-making tasks in power grids.

Papers:

• Gym-ANM: Reinforcement Learning Environments for Active Network Management Tasks in Electricity Distribution Systems
• Gym-ANM: Open-source software to leverage reinforcement learning for power system management in research and education

Key features

• Very little background in electricity systems modelling it required. This makes gym-anm an ideal starting point for RL students and researchers looking to enter the field.
• The environments (tasks) generated by gym-anm follow the Gymnasium framework, with which a large part of the RL community is already familiar.
• The flexibility of gym-anm, with its different customizable components, makes it a suitable framework to model a wide range of ANM tasks, from simple ones that can be used for educational purposes, to complex ones designed to conduct advanced research.

Installation

Requirements

gym-anm requires Python 3.10+ and can run on Linux, MaxOS, and Windows. Some rendering features may not work properly on Windows (not tested).

If you need Python 3.8 or 3.9, you can use gym-anm < 2.0.

We recommend installing gym-anm in a Python environment (e.g., virtualenv or conda).

Using pip

Using pip (preferably after activating your virtual environment):

pip install gym-anm

Building from source

Alternatively, you can build gym-anm directly from source:

git clone https://github.com/robinhenry/gym-anm.git
cd gym-anm
pip install -e .

Example

The following code snippet illustrates how gym-anm environments can be used. In this example, actions are randomly sampled from the action space of the environment ANM6Easy-v0. For more information about the agent-environment interface, see the official Gymnasium documentation.

import gymnasium as gym
import time

def run():
   env = gym.make('gym_anm:ANM6Easy-v0')
   o = env.reset()

   for i in range(100):
       a = env.action_space.sample()
       o, r, done, info = env.step(a)
       env.render()
       time.sleep(0.5)  # otherwise the rendering is too fast for the human eye.

   env.close()

if __name__ == '__main__':
    run()

The above code would render the environment in your default web browser as shown in the image below:

Additional example scripts can be found in examples/.

Testing the installation

All unit tests in gym-anm can be ran from the project root directory with:

python -m pytest tests
