Released Examples

Welcome to the released examples section of the project oemof_heat. Here you find models and applications that were used in published research of the project. We apply the Open Energy Modelling Framework oemof in energy system analysis for dispatch and system optimizations. Our work focuses on modelling heat components with linear programming, e.g., combined heat and power plants (CHP), heat pumps, district heating networks and solar thermal collectors.

List of currently available models:

  • Highly flexible Combined Heat and Power Production (flexCHP)
  • Highly flexible Combined Heat and Power Production - System Optimization (flexCHP_SysOpt)

Please contact us if you have any questions regarding the models or the input data, if you are struggling with the installation or if you have ideas for enhancements or further research.

Model description

flexCHP

Dispatch optimization. Scenario comparison.
Published research:
J. Wolf, C. Pels Leusden, S. Köhler, and J. Launer, “Flexibilisierung von KWK-Anlagen für wachsende Herausforderungen einer sicheren strom- und wärmeversorgung,” in 2. Regenerative Energietechnik Konferenz (RET.Con), Nordhausen, 2019.

flexCHP_SysOpt

System and dispatch optimization. Sensitivity analysis.
Published research:
J. Wolf, C. Pels Leusden, S. Köhler, and J. Launer, “Optimization of Extended CHP Plants with Energy Storages – an Open-Source Approach,” in International Renewable Storage Conference (IRES 2019), Düsseldorf, 2019.

How to download and run a model?

In the following steps we describe how you get from here to running the script, solving the optimization program yourself and finally looking at the results. We assume that you have python installed already and that you are familiar with the basic use of a terminal (e.g., enter a command or navigate to a directory).

Preparation steps:

  • Download or clone this repo. Download the repository from this page (our GitHub repository) and unzip it to a local directory of your choice or use Git to clone this repository.

  • Install required packages. You can use the requirements.txt file and pip or install the packages listed in the requirements.txt file in any other way you are familiar with. If you want to use pip open a terminal, navigate to the downloaded directory and enter pip install -r requirements.txt.

  • Download and install Cbc (an open-source mixed integer linear programming solver). For instructions have a look at the oemof-documentation and scroll down to the section Solver, for Linux distributions, or Solver for Windows.

  • Run installation test (optional). By now you should have installed two essential requirements: oemof and the Cbc-solver. You can check whether both were installed successfully with the installation test provided by the oemof developer team. Simply run oemof_installation_test in your terminal. If you are using virtual environments (recommended but not necessary) make sure your run the test in the environment where oemof is installed. If the installation was successful, the following message will be displayed:

    *****************************
    Solver installed with oemof:

    cbc: working
    glpk: not working
    gurobi: not working
    cplex: not working

    *****************************
    oemof successfully installed.
    *****************************

  • Provide input data. The input data that needs to be provided differ from one model to another. How to handle the input data and how you can run the model with your own data is therefore described in the models individual readme-file.

  • Check settings in configuration file. You find a configuration file (*.yml) in the directory ./experiment_config/. It holds information and settings that are needed to run the program and solve the optimizations problem (e.g., solver settings, paths and file names of input data). The config file specifies your experiment. Its structure and content differs for each model and is therefore described individually in each model file.

  • Run the program. Open a terminal. Navigate to the source code directory (/src/) of the model you like to run (e.g., my-computer/path-to-downloaded-file/released_examples/flexCHP_SysOpt/src/). Enter python main.py.

  • Get the results. See description in the models individual readme-file.

  • Find out what else can be modelled with oemof! The oemof-developer team provides several examples for applications on there GitHub repository: github.com/oemof/oemof-examples.
