**ASSUME** is an open-source toolbox for agent-based simulations of European electricity markets, with a primary focus on the German market setup.
Developed as an open-source model, its primary objectives are to ensure usability and customizability for a wide range of users and use cases in the energy system modeling community.

## Introduction

A unique feature of the ASSUME toolbox is its integration of **Deep Reinforcement Learning** methods into the behavioral strategies of market agents. The model offers predefined agent representations for both the demand and generation sides that can be used as plug-and-play modules, simplifying the implementation of learning strategies.
This setup enables research into new market designs and dynamics in energy markets.

### What can the software do?
The main motivation of ASSUME is to overcome the limitations of fixed, rule-based behaviors in existing ABMs.
For this, it leverages advancements in artificial intelligence, particularly deep reinforcement learning (DRL), enabling agents to adapt their behavior dynamically in response to market conditions.
This approach is practical for modeling interactions among competing market participants and observing emergent patterns from these interactions.
To support market design analysis in transforming electricity systems, we developed the ASSUME framework - a flexible and modular agent-based modeling tool for electricity market research.
ASSUME enables researchers to customize components such as agent representations, market configurations, and bidding strategies, utilizing pre-built modules for standard operations.
With the setup in ASSUME, researchers can simulate strategic interactions in electricity markets under a wide range of scenarios, from comparing market designs and modeling congestion management to analyzing the behavior of learning storage operators and renewable producers.
The framework supports studies on bidding under uncertainty, regulatory interventions, and multi-agent dynamics, making it ideal for exploring emergent behavior and testing new market mechanisms.
ASSUME has been utilized in research studies addressing diverse questions in electricity market design and operation.
It has explored the role of complex bids, demonstrated the effects of industrial demand-side flexibility for congestion management, and advanced the explainability of emergent strategies in learning agents.

### Who is it made for?
The framework is versatile enough to be employed in smaller-scale projects, such as master's theses, while also robust enough for complex doctoral research or investigations conducted by industry professionals.
This accessibility and scalability make ASSUME suitable for many users, from early-career researchers to experienced professionals.

## Documentation

- [User Documentation](https://assume.readthedocs.io/en/latest/)
- [Installation Guide](https://assume.readthedocs.io/en/latest/installation.html)

## Installation

You can install ASSUME using [pip](https://pip.pypa.io/).
Choose the appropriate installation method based on your needs:

### Using pip

To install the core package:

```bash
pip install assume-framework
```

**To install with reinforcement learning capabilities:**

```bash
pip install 'assume-framework[learning]'
```

Please keep in mind that the above installation method will install the PyTorch package without CUDA support.
If you want to make use of your GPU with CUDA cores, please install PyTorch with GPU support separately as described [here](https://pytorch.org/get-started/locally/).

We also include **network-based market clearing algorithms** such as for the re-dispatch, zonal clearing with NTCs and nodal market clearing, which all require the PyPSA library.
To install the package with these capabilities, use:

```bash
pip install 'assume-framework[network]'
```

To install with all capabilities:

```bash
pip install 'assume-framework[all]'
```

### Timescale Database and Grafana Dashboards
The Timescale Database and Grafana Dashboard are used to store and represent simulation results.

If you want to use the supported TimescaleDB and integrated Grafana dashboards for scenario analysis, you can use the provided Docker Compose file.

Follow these steps:

1. Clone the repository and navigate to its directory:

```bash
git clone https://github.com/assume-framework/assume.git
cd assume
```

2. Start the database and Grafana using the following command:

```bash
docker compose up -d
```

This will launch a container for TimescaleDB and Grafana with preconfigured dashboards for analysis.
You can access the Grafana dashboards at `http://localhost:3000`.

### Using TensorBoard to display Learning Metrics
TensorBoard is used to visualize and monitor the learning progress during reinforcement learning training.

When running an example with learning capabilities, you can start TensorBoard to observe the learning process.
Use the following shell command to start TensorBoard:
```shell
tensorboard --logdir tensorboard
```

You can then head to `http://localhost:6006/` to view and evaluate the training progress.

Please note that TensorBoard should ideally be shut down via `Ctrl + C` every time you want to start a new simulation run in the same folder structure and want to overwrite existing results, as failing to do so may lead to conflicts deleting old logs.

## Trying out ASSUME and the provided Examples

To ease your way into ASSUME, we provided some tutorial notebooks and preconfigured example simulations in the examples folder.
The former are helpful if you would like to get an impression of how ASSUME works, as they present different functionalities of ASSUME condensed in specific notebooks, and the latter provides various example simulations ranging from 8 power plant examples to the representations of Germany for one year.

### The Tutorial Notebooks

You can run the tutorials locally using the notebooks [here](examples/notebooks) or use [Google Colab](https://assume.readthedocs.io/en/latest/examples_basic.html).
The tutorials begin with the basics of ASSUME, e.g., introducing a new unit, while the later tutorials cover more advanced use cases.

We particularly recommend these tutorials; more can be found at the linked pages:

### Preconfigured Examples

To explore the provided example simulations [here](examples/inputs), follow these steps:

1. Clone the repository and navigate to its directory:

```bash
git clone https://github.com/assume-framework/assume.git
cd assume
```

2. Quick Start:

There are three ways to run a simulation:

- Local:

```bash
python examples/examples.py
```

- Using the provided Docker setup:

If you have installed Docker and set up the Docker Compose file previously, you can select 'timescale' in `examples.py` before running the simulation.
This will save the simulation results in a Timescale database, and you can access the Dashboard at `http://localhost:3000`.

- Using the CLI to run simulations:

```bash
assume -s example_01b -db "postgresql://assume:assume@localhost:5432/assume"
```

For additional CLI options, run `assume -h`.
