h2_grid

The central module containing all code dealing with the H2 grid in eGon100RE

calculate_H2_capacity(pressure, diameter)[source]

Method for calculagting capacity of pipelines based on data input from FNB Gas

Parameters:

  • pressure (float) – input for pressure of pipeline

  • diameter (float) – input for diameter of pipeline

  • column_to_match (str) – matching column

  • treshhold (float) – matching percentage for succesfull comparison

Returns:

energy_flow (float) – transmission capacity of pipeline

connect_h2_grid_to_neighbour_countries(scn_name)[source]

Connect germand H2_grid with neighbour countries. All german H2-Buses wich were planned as connection points for Import/Export of Hydrogen to corresponding neighbours country, are based on Publication of FNB-GAS (https://fnb-gas.de/wasserstoffnetz-wasserstoff-kernnetz/).

Returns:

None

connect_saltcavern_to_h2_grid(scn_name)[source]

Connect each saltcavern with nearest H2-Bus of the H2-Grid and insert the links into the database

Returns:

None

download_h2_grid_data()[source]

Download Input data for H2_grid from FNB-Gas (https://fnb-gas.de/wasserstoffnetz-wasserstoff-kernnetz/)

The following data for H2 are downloaded into the folder ./datasets/h2_data:

  • Links (file Anlage_3_Wasserstoffkernnetz_Neubau.xlsx,

    Anlage_4_Wasserstoffkernnetz_Umstellung.xlsx, Anlage_2_Wasserstoffkernetz_weitere_Leitungen.xlsx)

Returns:

None

fix_h2_grid_infrastructure(df)[source]

Manuell adjustments for more accurate grid topology based on Detailmaßnahmenkarte der FNB-Gas [https://fnb-gas.de/wasserstoffnetz-wasserstoff-kernnetz/]

Returns:

df (<class ‘pandas.core.frame.DataFrame’>)

fuzzy_match(df1, df2, column_to_match, threshold=80)[source]

Method for matching input data of H2_grid with georeferenced data (even if the strings are not exact the same)

Parameters:

  • df1 (pandas.core.frame.DataFrame) – Input dataframe

  • df2 (pandas.core.frame.DataFrame) – georeferenced dataframe with h2_buses

  • column_to_match (str) – matching column

  • treshhold (float) – matching percentage for succesfull comparison

Returns:

matched (list) – list with all matched location names

insert_h2_pipelines(scn_name)[source]

Insert H2_grid based on input data from FNB-Gas.

read_h2_excel_sheets()[source]

Read downloaded excel files with location names for future h2-pipelines

Returns:

  • df_Neu (<class ‘pandas.core.frame.DataFrame’>)

  • df_Um (<class ‘pandas.core.frame.DataFrame’>)

  • df_Erw (<class ‘pandas.core.frame.DataFrame’>)

replace_pipeline(df, start, end, intermediate)[source]

Method for adjusting pipelines manually by splittiing pipeline with an intermediate point.

Parameters:

  • df (pandas.core.frame.DataFrame) – dataframe to be adjusted

  • start (str) – startpoint of pipeline

  • end (str) – endpoint of pipeline

  • intermediate (str) – new intermediate point for splitting given pipeline

Returns:

df (<class ‘pandas.core.frame.DataFrame’>) – adjusted dataframe
