Hi there, i have met a problem or error that is described as "ValueError: could not convert string to float: ‘’
What do you expect to happen?
I hope you can help me to solve this problem.
What have you tried so far?
I am trying to running this wind energy model.The all input data is from the sample data. But i can’t find the bathymetry data in the sample data profile.So i download bathymetry data from GEBCO datasets.So except for the bathymetry data, which is not from sample data, the rest is all from sample data. When I put these datasets into the model run, there was a error:"ValueError: could not convert string to float: "
Hi @JasonLee,
I’m sure one of our software team will be able to help you out with your specific problem if you’d like to continue to use the gebco data. The sample data for the bathymetry is “global_dem.tif” in the base data folder from the sample data downloads - i.e. in this zip file here.
One issue I see in your log is that you are missing or incorrectly have entered several variables.
“global_wind_energy_parameters.csv.gz” should be "“global_wind_energy_parameters.csv”
You are also missing “Land Polygon” (you can find this in the base_data folder too, named “global_polygon.shp”), Minimum Distance (m), and Maximum Distance (m). In older versions of the model, you could get away without entering these latter two variables (for example, version 3.10), but version 3.14 expects these. Once these are all addressed, you should be able to complete the model run.
Thank you a lot. i have run this model with the sample data. it seems like that i haven’t input this land polygon data.Now i try to use my own data to run this model. thank you again.Have a nice day!!!
Hi there,i find the file called parameters of turbine that has a new parameter, i can’t find it meaning in the guide.Could you please help me?what is the parameter of “turbines_per_circuit”
That is used to derive how much infield cable (between turbines) is used as part of the cost estimates. The model assumes a rectangular layout. It isn’t really designed to investigate wake losses from alternate layouts, if that is a research question you have.
