Solar resource/power forecasting

[williamhobbs]

I've published a small repo for energy forecasting tools, currently limited to just solar.

https://github.com/williamhobbs/energy-forecasting-tools

It currently works with with NOAA GFS, NOAA HRRR, and ECMWF IFS.

It uses Herbie to help put together timeseries point forecasts for one or many points, with some added steps to convert thing like cumulative and/or 3-hour solar radiation into hourly values more suitable for solar power modeling.

Here's a quick example getting resource data from IFS, and the repo includes examples for converting to power:

from forecast_solar import get_solar_forecast

latitude = 33.5
longitude = -86.8
init_date = '2024-06-05 6:00' # datetime the forecast model was initialized
resource_data = get_solar_forecast(
    latitude,
    longitude,
    init_date,
    length_hours=18, # 18 hours are included in the forecast
    lead_time_hours=3, # forecast starts 3 hours out from the init_date
    model='ifs', # use ECMWF IFS
)
resource_data[
    ['ghi','dni','dhi','temp_air','wind_speed']
              ].plot(drawstyle='steps-mid')
