Compact Energy System Modeling Tool (CESM)

This is a compact energy system modeling tool that can model different forms of energy carriers and the conversion processes that convert them to each other. The optimal output of the model determines how much should be invested in each part of the energy system to meet the energy demand and minimize costs.

An example of the German energy system is also provided. The results of the model are compatible with the results of the paper "Barbosa, Julia, Christopher Ripp, and Florian Steinke. Accessible Modeling of the German Energy Transition: An Open, Compact, and Validated Model. Energies 14, no. 23 (2021)"

Installation

1. Download and install the following software from their official websites:

   • Python (version 3.10 or above)
   • Gurobi

2. Set up a virtual environment: ```console

   python -m venv env env\Scripts\activate

3. Clone the repository: ```console

   git clone https://github.com/EINS-TUDa/CESM.git ```

4. Change the directory to the repository: ```console

   cd CESM ```

5. Install the package: ```console

   pip install -e . ```

Quick Start

1. Initialize the Runs directory: ```console

   cesm init ```

2. Run the available models located in the Data folder using the following command: ```console

   cesm run ```

   If you know the specific model to be run, you can alternatively use: ```console

   cesm run -m $MODEL_NAME -s $SCENARIO ```

3. After the run is finished, plot the results with the following command: ```console

   cesm plot ``` These steps will help you quickly set up and start using the Compact Energy System Modelling Tool (CESM).

ABSTRACT = {We present an easily accessible model for dispatch and expansion planning of the German multi-modal energy system from today until 2050. The model can be used with low efforts while comparing favorably with historic data and other studies of future developments. More specifically, the model is based on a linear programming partial equilibrium framework and uses a compact set of technologies to ease the comprehension for new modelers. It contains all equations and parameters needed, with the data sources and model assumptions documented in detail. All code and data are openly accessible and usable. The model can reproduce today’s energy mix and its CO2 emissions with deviations below 10%. The generated energy transition path, for an 80% CO2 reduction scenario until 2050, is consistent with leading studies on this topic. Our work thus summarizes the key insights of previous works and can serve as a validated and ready-to-use platform for other modelers to examine additional hypotheses.},
