AWE-SE

A repository establishing the coupling between interoperable external repositories repositories AWE-Power and AWE-Eco to setup workflows for system design of airborne wind energy (AWE). The framework is based on the field of multi-disciplinary design, analysis and optimisation (MDAO). It enables the design of AWE systems with an objective to minimise the levelised cost of energy (LCoE) and also other profit-based metrics.

How to cite

If you use the framework then please cite:

Joshi, R., von Terzi, D., and Schmehl, R.: System design and scaling trends for airborne wind energy, Wind Energ. Sci. Discuss. [preprint], https://doi.org/10.5194/wes-2024-161, in review, 2024.

Dependencies

The framework is built and tested in MATLAB R2021b (without additional add-ons). Try installing this version if your version of MATLAB does not execute the code successfully.

Installation

Please Clone the repository using the following command

git clone --recurse-submodules https://github.com/awegroup/AWE-SE

This will automatically download the interoperable external repositories AWE-Power and AWE-Eco as git submodules.

Overview of the repository

The Repository consists following folders:

1. AWE-Eco: External repository estimating cost of AWE systems included as a git submodule.
2. AWE-Power: External repository estimating power curve of AWE systems included as a git submodule.
3. inputFiles: Contains pre-defined input files.
4. outputFiles: Contains generated output files based on the pre-defined input files.
5. src: Contains the functions required to utilise the capabilities of the framework.
6. WES2025_paper: Contains scripts, input files and generated output files used to generate plots used in the associated journal publication mentioned in the citation.

Pre-defined example simulation

The script example_workFlow_AWE_Power_AWE_Eco_coupling.m can be directly executed to simulate with pre-defined input files.

It shows the workflow to couple AWE-Power and AWE-Eco.

inputFiles folder

1. A pre-defined file named inputFile_500kW_example.yml describes a 500kW system and is the input file required to run AWE-Power.
2. A pre-defined file named eco_cost_inputs_GG_fixed.xlsx describes the initialization of AWE-Eco.
3. A pre-defined file named eco_system_inputs_awePower.m describes the coupling between variables of AWE-Power and AWE-Eco.

outputFiles folder

The generated output files have a prefix as alpha-numeric text mentioned under the name field in the input file. Following .mat files are automatically saved in the outputFiles folder at the end of every simulation.

AWE-Power outputs

1. optimDetails has the details regarding the optimization.
2. outputs has all the raw outputs.
3. processedOutputs has post-processed relevant outputs for better visualization.

AWE-Eco outputs

1. inp has the definition of the system taken from the outputs of AWE-Power.
2. par has the cost parameters as defined in eco_cost_inputs_GG_fixed.xlsx.
3. eco has the final outputs.

To run with user-defined inputs

Create your own input files preserving the format and the structure as described by the pre-defined input files and use the example_workFlow_AWE_Power_AWE_Eco_coupling.m as a reference for execution.
