A package for the simulation and control of power systems

CommonPower

Introduction

CommonPower provides a flexible framework to model power systems, interface to single-agent and multi-agent RL controllers, and maintain safety based on a symbolic representation of the system equations. Alternatively, the system model can directly be used to solve a given use case via the built-in model predictive controller. Following a modular design philosophy, CommonPower is an easily extendable tool for the development and benchmarking of RL controllers in the context of smart grids. The initial focus is on energy management and economic dispatch. Additionally, CommonPower readily allows the influence of forecast quality to be studied. The primary features are

• an object-oriented approach to modelling power system entities,

• a Pyomo-based symbolic math representation of entities to obtain all relevant system equations in the background,

• interfaces for single/multi-agent reinforcement learning and optimal control,

• a flexible interface to make use of diverse data sources and forecasting models.

Installing CommonPower

You will need Python >= 3.8 installed on your system.

We recommend using a virtual environment to work with CommonPower. To create a virtual environment run

python -m venv </path/to/new/virtual/environment>

You can then activate the virtual environment.

Linux:

source <path/to/venv>/bin/activate

Windows:

<path/to/venv>\Scripts\activate.bat

You can then proceed to install CommonPower. For local development, install the library in editable mode:

cd <your/working/directory>
git clone "https://github.com/TUMcps/commonpower.git"
pip install -e <absolute/path/to/the/commonpower/directory>

Otherwise, install CommonPower via PyPI:

pip install commonpower

Multi-agent reinforcement learning

At the moment, CommonPower supports multi-agent reinforcement learning using the IPPO/MAPPO implementation detailed in this paper. Since we had to make a few adjustments, we forked the original repository. Please clone our fork, cd into the repository and install the package to your virtual environment using pip install -e ..

Gurobi

We use Gurobi as a default solver for our optimization problems. As a student, you can obtain an academic license. There are two options: If you want to run CommonPower on you laptop, you can use the named-user license. To run it on a server, you need the WLS license. After obtaining a license, follow the Gurobi quickstart guide (choose the appropriate one for your system) to install Gurobi and retrieve your license. If you use Gurobi on a server (with the WLS license) and receive the error that it requires two many cores, you can just submit a ticket with the error message and your WLS license will be upgraded.
