GREECE is a pre-processing model used to extract geographical candidate sites for further selection of optimal RE sites (location and size) using combinatorial optimization.

GREECE processes various geographic layers (areas, networks, terrain, resource) with respect to various range control parameters (buffer, threshold, surface area). It is composed of several sub-models, at the moment for solar GHI synthetic generation, PV conversion, or else road transportation. The model is written in Python and the interface is made through configuration files and Shell scripts.

The easiest way to install greece is through Pypi. In your preferred virtual environment, just type in:

$ pip install greece

Here's the list of what is done and what remains to be done:

• Constraint model
• Solar GHI model
• PV conversion model
• Biomass model
• Hydro model
• Wind model
• Storage model
• Terrain-based effects on solar radiation (horizon obstruction + altitude)
• PostgreSQL interface for input data
• Power Flow model for further analysis of network voltage stability
• Link to CPLEX optimization within Python (through cplex or pyomo)

First, add "/greece/rentools/shell_scripts" directory to your global path (using ~/.bashrc or ~/.profile files). Make all python scripts executable, e.g.:

$ sudo chmod +x solar_ghi.py

Then, build configuration directory ("greece_%s_config" with %s={'solar', 'pv', 'biomass'}) for your problem such as:

$ build_config.py --type solar /path/to/dir/where/config/must/be/stored

Fill corresponding config files. Finally, you can call the script corresponding to the model you want to run. Typical usage is:

$ solar_ghi.py path/to/corresponding/config/folder
