MIDAS Weather

Description

This package contains a Midas module providing a simulator for weather data.

Although this package is intendet to be used with Midas, it does not depend on anything Midas-related except for the midas-util package. You can use it in any mosaik simulation scenario.

Installation

This package will usually be installed automatically together with midas-mosaik. It is available on pypi, you can install it manually with

pip install midas-weather

Usage

The complete documentation is available at https://midas-mosaik.gitlab.io/midas.

Inside of Midas

To use the weather data inside of Midas, add weather to your modules

my_scenario:
  modules:
    - weather
    - ...

and configure it with

  weather_params:
    my_weather_scope:
      weather_mapping:
        WeatherCurrent:
          - interpolate: true
            randomize: true

If a store module is enabled, the weather module will automatically send all outputs to the store.

Any mosaik scenario

If you don't use Midas, you can add the weather manually to your mosaik scenario file. First, the entry in the sim_config:

sim_config = {
    "WeatherData": {"python": "midas.modules.weather.simulator:WeatherDataSimulator"},
    # ...
}

Next, you need to define start_date and step_size. The start_date is to be provided as ISO datestring and can anything between 2009 and 2022:

start_date = "2021-06-08 14:00:00+0000"

The step_size can be anything between 1 and 3600. Higher values might be possible, but this is untested.

Now, the simulator can be started:

weather_sim = world.start("WeatherData", step_size=900, start_date=start_date)

Next, a weather data model can be started:

weather_model = weather_sim.WeatherCurrent(interpolate=True, randomize=True)

Finally, the model needs to be connected to other models:

world.connect(weather_model, other_entity, "t_air_deg_celsius", "wind_v_m_per_s")
