mosaik-pv 1.1

PV Simulator for Mosaik

This component was initially created by Cornelius Steinbrink based on PyPVSim by Daniel Soto, which is licensed under CC-BY 3.0). It was further extended by Thomas Raub and updated by Jan Sören Schwarz and Danila Valko.

The PV system simulator calculates active power output based on the Direct Normal Irradiance (DNI, [W/m2]) input and current time (hourly).

PV system output data:

• P[MW] - active power produced

PV system input data:

• DNI[W/m2] - Direct Normal Irradiance

• scale_factor - multiplies output [coef]

Configuration:

• latitude [grad]

• area - insolated panels area [m2]

• efficiency [coef]

• el_tilt - elevation [grad]

• az_tilt - azimuth [grad]

An example scenario is located in the ´demo´ folder.

Other options

Please pay attention to the input data. If you want to use only Direct Normal Irradiance input data as part of the co-simulation, then mosaik-pv is suitable, if you want to use full weather information (global irradiance, wind speed, air temperature and pressure) then mosaik-pvlib is suitable. If you are satisfied with historical performance estimates for a particular location or have no other input data, then mosaik-pvgis is the best solution which is based on PVGIS performance data.

Installation

• To use this project, you have to install at least version 3.2.0 of mosaik

• It is recommended, to use the Mosaik-CSV Library to import DNI data

If you don’t want to install this project through PyPI, you can use pip to install the requirements.txt file:

pip install -r requirements.txt

How to Use

Specify simulators configurations within your scenario script:

LAT = 32.0
AREA = 1
EFF = 0.5
EL = 32.0
AZ = 0.0
START = "2014-01-01 01:00:00"
END = 3600 * 24
STEP_SIZE = 60 * 60
DNI_DATA = "solar_data.csv"


SIM_CONFIG = {
    'DNISim': {
        'python': 'mosaik_csv:CSV'
    },
    'PVSim': {
        'python': 'mosaik_components.pv.pvadapter:PvAdapter'
    },
    ...
}

Initialize the PV- and DNI-simulator:

# Create DNI simulator
DNI_sim = world.start("DNISim",
                    sim_start=START,
                    datafile=DNI_DATA)

# Create PV system with certain configuration
pv_sim = world.start(
                    "PVSim",
                    start_date=START,
                    step_size=STEP_SIZE)

Instantiate model entities:

DNI_model = DNI_sim.DNI.create(1)

pv_model = pv_sim.PV.create(1, latitude=LAT, area=AREA,
                        efficiency=EFF, el_tilt=EL, az_tilt=AZ)

Connect DNI input with PV-simulator:

world.connect(
                    DNI_model[0],
                    pv_model[0],
                    ("DNI", "DNI[W/m2]"),
                )

CSV-Formatting

For the simulator to work correctly, both .csv files have to be specifically formatted!

DNI-data

The meteo_data.csv is formatted accordingly to the conventions of the mosaik_csv simulator:

Wind
Date,wind_speed
YYYY-MM-DD HH:mm:ss,v1
YYYY-MM-DD HH:mm:ss,v2
...
DNI
Time,DNI
YYYY-MM-DD HH:mm:ss,2.1,92.0,0.0,0.0

• Each entry in the .csv needs a Date in the YYYY-MM-DD HH:mm:ss format and a set of values.
