Arguments

profile_id

load profile identifier, required

start_date

start date in ISO 8601 format, required

end_date

end date in ISO 8601 format, required

state_code

identifier for one of 16 German states, optional

Value

A data.frame with four variables:

  • profile_id, character, load profile identifier

  • start_time, POSIXct / POSIXlt, start time

  • end_time, POSIXct / POSIXlt, end time

  • watts, numeric, electric power

Details

In regards to the electricity market in Germany, the term "Standard Load Profile" refers to a representative pattern of electricity consumption over a specific period. These profiles can be used to depict the expected electricity consumption for various customer groups, such as households or businesses.

For each distinct combination of profile_id, period, and day, there are 96 x 1/4 hour measurements of electrical power. Values are normalized so that they correspond to an annual consumption of 1,000 kWh. That is, summing up all the quarter-hourly consumption values for one year yields an approximate total of 1,000 kWh/a; for more information, refer to the 'Examples' section, or call vignette("algorithm-step-by-step").

In total there are 11 profile_id for three different customer groups:

  • Households: H0

  • Commercial: G0, G1, G2, G3, G4, G5, G6

  • Agriculture: L0, L1, L2

For more information and examples, call slp_info().

Period definitions:

  • summer: May 15 to September 14

  • winter: November 1 to March 20

  • transition: March 21 to May 14, and September 15 to October 31

Day definitions:

  • workday: Monday to Friday

  • saturday: Saturdays; Dec 24th and Dec 31th are considered a Saturdays too if they are not a Sunday

  • sunday: Sundays and all public holidays

Note: The package supports public holidays for Germany, retrieved from the nager.Date API. Use the optional argument state_code to consider public holidays on a state level too. Allowed values are listed below:

  • DE-BB: Brandenburg

  • DE-BE: Berlin

  • DE-BW: Baden-Württemberg

  • DE-BY: Bavaria

  • DE-HB: Bremen

  • DE-HE: Hesse

  • DE-HH: Hamburg

  • DE-MV: Mecklenburg-Vorpommern

  • DE-NI: Lower-Saxony

  • DE-NW: North Rhine-Westphalia

  • DE-RP: Rhineland-Palatinate

  • DE-SH: Schleswig-Holstein

  • DE-SL: Saarland

  • DE-SN: Saxony

  • DE-ST: Saxony-Anhalt

  • DE-TH: Thuringia

start_date must be greater or equal to "1990-01-01". This is because public holidays in Germany would be ambitious before the reunification in 1990 (think of the state of Berlin in 1989 and earlier).

end_date must be smaller or equal to "2073-12-31" because this is last year supported by the nager.Date API.

Examples

start <- "2024-01-01"
end <- "2024-12-31"

# multiple profile IDs are supported
L <- slp_generate(c("L0", "L1", "L2"), start, end)
head(L)

# you can specify one of the 16 ISO 3166-2:DE codes to take into
# account holidays determined at the level of the federal states
berlin <- slp_generate("H0", start, end, state_code = "DE-BE")

# for convenience, the codes can be specified without the prefix "DE-"
identical(berlin, slp_generate("H0", start, end, state_code = "BE"))
#> [1] TRUE

# state codes are not case-sensitive
identical(berlin, slp_generate("H0", start, end, state_code = "de-be"))
#> [1] TRUE

# consider only nationwide public holidays
H0_2024 <- slp_generate("H0", start, end)

# electric power values are normalized to consumption of ~1,000 kWh/a
sum(H0_2024$watts / 4 / 1000)
