Midas PV and Wind Data Simulator

The pwdata module, provided by the midas-pwdata package, provides a simulator for PV and wind time series.

Version: 2.1

Installation

This package will usually installed automatically together with midas-mosaik, if you opt-in the bh extra. It is available on pypi, so you can install it manually with

    pip install midas-pwdata

Usage

The intended use-case for the time simulator is to be used inside of midas. However, it can be used in any mosaik simulation scenario.

Inside of midas

To use the pwdata inside of midas, simply add pwdata to your modules

    my_scenario:
      modules:
        - pwdata
        # - ...

and provide a scope and a configuration:

    my_scenario:
      # ...
      pwdata_params:
        my_grid_scope:
          interpolate: True
          randomize_data: True
          randomize_cos_phi: True
          active_mapping:
            16: [[onshore_p_mw, 5]]
            17: [[solar_p_mw, 0.03]]
            20: [[solar_p_mw, 0.41]]

The mapping has to match to the grid that you're using.

Any Mosaik Scenario

If you don't use midas, you can add the pwdata manually to your mosaik scenario_ file. First, the entry in the sim_config:

    sim_config = {
        "PVWindData": {"python": "midas_powerseries.simulator:PowerSeriesSimulator"},
        # ...
    }

Next, you need to start the simulator (assuming a step_size of 900):

    pw_sim = world.start(
        "PVWindData",
        step_size=900,
        data_step_size=3600,
        is_load=False,
        is_sgen=True,
        start_date="2020-01-01 00:00:00+0100",
        data_path="/path/to/folder/where/dataset/is/located/",
        filename="pvwind_profiles.csv",  # this is default
    )

Then the models can be started:

    wind = pw_sim.CalculatedQTimeSeries(name="on_shore_p_mw", scaling=5)
    pv1 = pw_sim.CalculatedQTimeSeries(name="solar_p_mw", scaling=0.03)
    pv2 = pw_sim.CalculatedQTimeSeries(name="solar_p_mw", scaling=0.41)

Finally, the modells need to be connected to other entities:

    world.connect(wind, other_entity, "p_mw", "q_mvar")
