edisgo.flex_opt.costs

Module Contents

Functions

grid_expansion_costs(edisgo_obj[, ...])	Calculates topology expansion costs for each reinforced transformer and line
line_expansion_costs(edisgo_obj, lines_names)	Returns costs for earthworks and per added cable as well as voltage level

edisgo.flex_opt.costs.grid_expansion_costs(edisgo_obj, without_generator_import=False)

Calculates topology expansion costs for each reinforced transformer and line in kEUR.

edisgo.flex_opt.costs.edisgo_obj

Type

EDisGo

edisgo.flex_opt.costs.without_generator_import

If True excludes lines that were added in the generator import to connect new generators to the topology from calculation of topology expansion costs. Default: False.

Type

bool

Returns

DataFrame containing type and costs plus in the case of lines the line length and number of parallel lines of each reinforced transformer and line. Index of the DataFrame is the name of either line or transformer. Columns are the following:

typestr

Transformer size or cable name

total_costsfloat

Costs of equipment in kEUR. For lines the line length and number of parallel lines is already included in the total costs.

quantityint

For transformers quantity is always one, for lines it specifies the number of parallel lines.

line_lengthfloat

Length of line or in case of parallel lines all lines in km.

voltage_levelstr {‘lv’ | ‘mv’ | ‘mv/lv’}

Specifies voltage level the equipment is in.

mv_feederLine

First line segment of half-ring used to identify in which feeder the network expansion was conducted in.

Return type

pandas.DataFrame<DataFrame>

Notes

Total network expansion costs can be obtained through self.grid_expansion_costs.total_costs.sum().

edisgo.flex_opt.costs.line_expansion_costs(edisgo_obj, lines_names)

Returns costs for earthworks and per added cable as well as voltage level for chosen lines in edisgo_obj.

Parameters

• edisgo_obj (EDisGo) – eDisGo object of which lines of lines_df are part

• lines_names (list of str) – List of names of evaluated lines

Returns

costs – Dataframe with names of lines as index and entries for ‘costs_earthworks’, ‘costs_cable’, ‘voltage_level’ for each line

Return type

pandas.DataFrame
