Welcome to a journey through PowerGridworld, an innovative framework designed specifically for creating multi-agent environments in the realm of power systems. This framework caters to the growing need for effective reinforcement learning (RL) solutions tailored to heterogeneous power systems.

What is PowerGridworld?

PowerGridworld provides users with a robust, modular, and customizable framework to develop multi-agent Gym environments. It stands out in its ability to integrate seamlessly with popular reinforcement learning training frameworks, making it an essential tool for researchers and developers in the field.

While various frameworks exist for training multi-agent RL policies, PowerGridworld allows users to rapidly prototype and develop environments, especially crucial for complex power systems requiring dynamic power flow solutions. Designed with user-friendliness in mind, this open-source package is dedicated to making the development and training process simpler and more efficient.

Key Features of PowerGridworld

• Lightweight and modular framework
• Customizable for specific power systems
• Integration with existing RL frameworks like OpenAI’s MADDPG and RLLib’s PPO
• Default incorporation of power flow solutions into agent rewards

Installing PowerGridworld

Ready to dive in? Here’s a step-by-step guide to install PowerGridworld:

1. Set up your environment:
• Run the command: conda create -n gridworld python=3.8 -y
• Activate the environment: conda activate gridworld
2. Clone the PowerGridworld repository:

git clone git@github.com:NRELPowerGridworld.git

3. Navigate into the directory:

cd PowerGridWorld

4. Install the package:
• pip install -e .
• pip install -r requirements.txt
5. For users of poetry, simply run:

poetry install

6. Run tests to ensure everything is set:

pytest tests

pytest –nbmake examples

Understanding the Code: An Analogy

Think of PowerGridworld as a Lego set designed for building cities but specifically tailored for power systems. The instructions you follow to build a complex city represent the installation commands and framework features. Each unique piece, such as different buildings or roads, corresponds to the various modules and customizable aspects you can configure within PowerGridworld.

Just like assembling Lego blocks requires careful attention to detail, installing PowerGridworld involves specific commands to ensure you have all necessary components in place. If you miss a piece or choose the wrong block, your city—or in this case, your power systems—might not function as expected.

Examples of PowerGridworld in Action

Once installed, you can explore various environments and MARL training algorithms provided in the examples directory. This is your playground to understand how agents interact within the framework and how RL policies can be applied.

Troubleshooting Tips

If you encounter issues during installation or usage, consider the following troubleshooting ideas:

• Ensure that you are using the correct version of Python (3.8).
• Check that you have activated your conda environment before running installation commands.
• Revisit the command syntax for any typos while cloning or installing the repositories.
• If tests fail, attempt to update your pip and packages to their latest versions.
