netallocation.utils module¶
This module contains tool functions for making the life easier in the other modules.
- netallocation.utils.as_dense(ds)[source]¶
Convert sparse dataset/dataarray into a dense dataset.
- Parameters
ds (xr.Dataset or xr.DataArray) –
- Returns
Dataset or DataArray with dense data.
- Return type
xr.Dataset or xr.DataArray
- netallocation.utils.as_sparse(ds)[source]¶
Convert dense dataset/dataarray into a sparse dataset.
- Parameters
ds (xr.Dataset or xr.DataArray) –
- Returns
Dataset or DataArray with sparse data.
- Return type
xr.Dataset or xr.DataArray
- netallocation.utils.bus_distances(n)[source]¶
Calculate the geographical distances between all buses.
- Parameters
n (pypsa.Network) –
- Returns
Distance matrix of size N x N, with N being the number of buses.
- Return type
xr.DataArray
- netallocation.utils.check_carriers(n)[source]¶
Ensure if carrier of stores is defined.
- Parameters
n (pypsa.Network) –
- netallocation.utils.check_dataset(ds)[source]¶
Ensure the argument is an xarray.Dataset.
If the argument was a Dataset, the a tupel (ds, True) is returned, if it isn’t’ a Dataset a tuple of the (Dataset(ds), False) is returned.
- netallocation.utils.check_one_port_comps(arg, n)[source]¶
Set argument to n.one_port_components if None
- netallocation.utils.check_passive_branch_comps(arg, n)[source]¶
Set argument to n.passive_branch_components if None
- netallocation.utils.filter_null(da, dim=None)[source]¶
Drop all coordinates with only null/nan entries on dimensions dim.
- netallocation.utils.get_branches_i(n, branch_components=None)[source]¶
Get a pd.Multiindex for all branches in the network.
- netallocation.utils.get_ext_branches_i(n, branch_components=None)[source]¶
Get a pd.Multiindex for all extendable branches in the network.
- netallocation.utils.get_ext_one_ports_i(n, per_carrier=True)[source]¶
Get a pd.Multiindex for all extendable branches in the network.
- netallocation.utils.get_non_ext_branches_i(n, branch_components=None)[source]¶
Get a pd.Multiindex for all non-extendable branches in the network.
- netallocation.utils.get_non_ext_one_ports_i(n, per_carrier=True)[source]¶
Get a pd.Multiindex for all non-extendable branches in the network.
- netallocation.utils.is_sparse(ds)[source]¶
Check if a xarray.Dataset or a xarray.DataArray is sparse.
- Parameters
ds (xarray.Dataset or xarray.DataArray) –
- Returns
- Return type
Bool
- netallocation.utils.obj_if_acc(obj)[source]¶
Get the object of underying Accessor if Accessor is passed.
This function is usefull to straightforwardly make functions through the AllocationAccessor accessible.
- Parameters
obj (AllocationAccessor or xarray.Dataset) –
- Returns
Dataset of the accessor if accessor was is passed, ingoing object otherwise.
- Return type
obj
- netallocation.utils.reindex_by_bus_carrier(df, c, n)[source]¶
Group a time-dependent dataframe by bus and carrier.
- Parameters
df (pd.DataFrame) – Time-dependent series to group, e.g. n.generators_t.p
c (str) – Component name of the underlying data.
n (pypsa.Network) –
- Returns
Grouped array with dimension (‘snapshot’, ‘bus’, ‘carrier’).
- Return type
xarray.DataArray
- netallocation.utils.set_default_if_none(arg, n, attr)[source]¶
Set any argument to an attribute of n if None
- netallocation.utils.split_branches(ds, n)[source]¶
Split data into extendable one ports and nonextendable one ports
