BDEW Load Profiles

Using the oemof-demand you can create heat and electrical profiles by scaling the BDEW profiles to your desired annual demand. The BDEW profiles are the standard load profiles from BDEW.

Heat Profiles

Description

Heat profiles are created according to the approach described in the corresponding BDEW guideline.

The method was originally established in this PhD Thesis at TU Munich.

The approach for generating heat demand profiles is described in section 4.1 (Synthetic load profile approach).

Q_{day}(\theta) = KW \cdot h(\theta) \cdot F \cdot SF

KW: Kundenwert (customer value). Daily consumption of customer at \approx 8 ^\circ C, depending on SLP type and Temperature timeseries.
h: h-Wert (h-value) , depending on SLP type and daily mean temperature.
F: Wochentagsfaktor (week day factor), depending on SLP type and day of the week.
T: Daily mean temperature 2 meters above the ground (simple mean or “geometric series”, which means a weighted sum over the previous days).
SF: Stundenfaktor (hour factor)

The geometric series approach is meant to account for thermal inertia.

\theta = \frac{T_t + 0.5 \cdot T_{t-1} + 0.25 \cdot T_{t-2} + 0.125 \cdot T_{t-3}}{1 + 0.5 + 0.25 + 0.125}

Depending on the profile type, different coefficients A, B, C, D for the sigmoid function are used.

h(\theta) &= \frac{A}{1+(\frac{B}{\theta-\theta_0})^C} + D \\ \theta_0 &= 40^\circ C

Types of houses:

EFH: Einfamilienhaus (single family house)
MFH: Mehrfamilienhaus (multi family house)
GMK: Metall und Kfz (metal and automotive)
GHA: Einzel- und Großhandel (retail and wholesale)
GKO: Gebietskörperschaften, Kreditinstitute und Versicherungen (Local authorities, credit institutions and insurance companies)
GBD: sonstige betriebliche Dienstleistung (other operational services)
GGA: Gaststätten (restaurants)
GBH: Beherbergung (accommodation)
GWA: Wäschereien, chemische Reinigungen (laundries, dry cleaning)
GGB: Gartenbau (horticulture)
GBA: Backstube (bakery)
GPD: Papier und Druck (paper and printing)
GMF: haushaltsähnliche Gewerbebetriebe (household-like business enterprises)
GHD: Summenlastprofil Gewerbe/Handel/Dienstleistungen (Total load profile Business/Commerce/Services)

Building class:

The parameter building_class (German: Baualtersklasse) can assume values in the range 1-11.

Electrical Profiles

Description

The electrical profiles are the standard load profiles from BDEW. All profiles have a resolution of 15 minutes. They are based on measurements in the German electricity sector. There is a dynamic function (h0_dyn) for the houshold (h0) profile that better takes the seasonal variance into account [BDEW].

F_t = -3,92\cdot10^{-10} \cdot t^4 + 3,2\cdot10^{-7} \cdot t^3– 7,02\cdot10^{-5}\cdot t^2 + 2,1\cdot10^{-3}\cdot t + 1,24

With t the day of the year as a decimal number.

The following profile types are available. Be aware that the types in Python code are strings in lowercase.

Usage

from oemof.demand import bdew
e_slp = bdew.ElecSlp(year=2020)

# get all available types
print(e_slp.get_profiles().columns)

# get the "h0" and "g0" profile
profiles = e_slp.get_profiles("h0", "g0")

# get scaled profiles
scaled_profiles = e_slp.get_scaled_profiles({"h0": 3000, "g0": 5000})

# get scaled profiles with power values instead of energy values
# a conversion_factor of 4 will convert Wh, kWh etc. to W, kW
e_slp.get_scaled_power_profiles({"h0": 3000, "g0": 5000}, conversion_factor=4)

# add holidays, holidays are treated as Sundays
holidays = {
    datetime.date(2010, 1, 1): "New year",
    datetime.date(2010, 10, 3): "Day of German Unity",
}
e_slp = bdew.ElecSlp(year=2010, holidays=holidays)
