Creates a new batch handler of (existing) objects
- batch_new(names: Optional[List[AnyStr]] = None, *, df=None, count: Optional[int] = None, begin_edit: Optional[bool] = None, **kwargs: typing_extensions.Unpack[altdss.Reactor.ReactorBatchProperties]) altdss.Reactor.ReactorBatch #
Creates a new batch of Reactor objects
Either
names
,count
ordf
is required.- Parameters:
begin_edit – The argument
begin_edit
indicates if the user want to leave the elements in the edit state, and requires a call toend_edit()
or equivalent. The defaultbegin_edit
is set toNone
. WithNone
, the behavior will be adjusted according the default of how the batch is created.**kwargs – Pass keyword arguments equivalent to the DSS properties of the object.
names – When using a list of names, each new object will match the names from this list.
begin_edit
defaults toTrue
if no arguments for properties were passed,False
otherwise.count – When using
count
, new objects will be created with based on a random prefix, with an increasing integer up tocount
.begin_edit
defaults toTrue
if no arguments for properties were passed,False
otherwise.df – Currently EXPERIMENTAL AND LIMITED, tries to get the columns from a dataframe to populate the names and the DSS properties.
begin_edit
defaults toFalse
.
- Returns:
Returns the new batch of DSS objects, wrapped in Python.
Note that, to make it easier for new users where the edit context might not be too relevant, AltDSS automatically opens/closes edit contexts for single properties if the object is not in the edit state already.
- begin_edit() None #
Marks for editing all DSS objects in the batch
In the editing mode, some final side-effects of changing properties are postponed until
end_edit
is called. This side-effects can be somewhat costly, like updating the model parameters or internal matrices.If you don’t have any performance constraint, you may edit each property individually without worrying about using
begin_edit
andend_edit
. For convenience, those are emitted automatically when editing single properties outside an edit block.
- edit(**kwargs: typing_extensions.Unpack[altdss.Reactor.ReactorBatchProperties]) altdss.Reactor.ReactorBatch #
Edit this Reactor batch.
This method will try to open a new edit context (if not already open), edit the properties, and finalize the edit context for objects in the batch. It can be seen as a shortcut to manually setting each property, or a Pythonic analogous (but extended) to the DSS
BatchEdit
command.- Parameters:
**kwargs – Pass keyword arguments equivalent to the DSS properties of the objects.
- Returns:
Returns itself to allow call chaining.
- end_edit(num_changes: int = 1) None #
Leaves the editing states of all DSS objects in the batch
num_changes
is required for a few classes to correctly match the official OpenDSS behavior and must be the number of properties modified in the current editing block. As of DSS C-API v0.13, this is only required for the Monitor class, when theAction
property is used with theProcess
value.
- find(name_or_idx: Union[AnyStr, int]) altdss.DSSObj.DSSObj #

- new(name: AnyStr, *, begin_edit: Optional[bool] = None, activate=False, **kwargs: typing_extensions.Unpack[altdss.Reactor.ReactorProperties]) altdss.Reactor.Reactor #
Creates a new Reactor.
- Parameters:
name – The object’s name is a required positional argument.
activate – Activation (setting
activate
to true) is useful for integration with the classic API, and some internal OpenDSS commands. If you interact with this object only via the Alt API, no need to activate it (due to performance costs).begin_edit – This controls how the edit context is left after the object creation:
True
: The object will be left in the edit state, requiring anend_edit
call or equivalent.False
: No edit context is started.None
: If no properties are passed as keyword arguments, the object will be left in the edit state (assumes the user will fill the properties from Python attributes). Otherwise, the internal edit context will be finalized.
- Parameters:
**kwargs – Pass keyword arguments equivalent to the DSS properties of the object.
- Returns:
Returns the new DSS object, wrapped in Python.
Note that, to make it easier for new users where the edit context might not be too relevant, AltDSS automatically opens/closes edit contexts for single properties if the object is not in the edit state already.

Multiple properties can be listed to allow filtering various conditions.
Example for loads:
# Create an initial batch using a regular expression abc_loads = altdss.Load.batch(re=r'^abc.*$') # a batch of all loads with names starting with "abc" abc_loads_filtered = abc_loads.batch(Class=1, Phases=1, kV=(0.1, 1.0)) # Create an initial batch, already filtered abc_loads_filtered = altdss.Load.batch(re=r'^abc.*$', Class=1, Phases=1, kV=(0.1, 1.0))
- begin_edit() None #
Marks for editing all DSS objects in the batch
In the editing mode, some final side-effects of changing properties are postponed until
end_edit
is called. This side-effects can be somewhat costly, like updating the model parameters or internal matrices.If you don’t have any performance constraint, you may edit each property individually without worrying about using
begin_edit
andend_edit
. For convenience, those are emitted automatically when editing single properties outside an edit block.
- edit(**kwargs: typing_extensions.Unpack[altdss.Reactor.ReactorBatchProperties]) altdss.Reactor.ReactorBatch #
Edit this Reactor batch.
This method will try to open a new edit context (if not already open), edit the properties, and finalize the edit context for objects in the batch. It can be seen as a shortcut to manually setting each property, or a Pythonic analogous (but extended) to the DSS
BatchEdit
command.- Parameters:
**kwargs – Pass keyword arguments equivalent to the DSS properties of the objects.
- Returns:
Returns itself to allow call chaining.
- end_edit(num_changes: int = 1) None #
Leaves the editing states of all DSS objects in the batch
num_changes
is required for a few classes to correctly match the official OpenDSS behavior and must be the number of properties modified in the current editing block. As of DSS C-API v0.13, this is only required for the Monitor class, when theAction
property is used with theProcess
value.
- kV: altdss.ArrayProxy.BatchFloat64ArrayProxy#
‘property(…)’
For 2, 3-phase, kV phase-phase. Otherwise specify actual coil rating.
DSS property name:
kV
, DSS property index: 5.
- kvar: altdss.ArrayProxy.BatchFloat64ArrayProxy#
‘property(…)’
Total kvar, all phases. Evenly divided among phases. Only determines X. Specify R separately
DSS property name:
kvar
, DSS property index: 4.
- pctEmergency(allNodes=False) altdss.types.Float64Array #
For each element in the batch, calculate the maximum current across the conductors as a percentage of the emergency ampere rating.
By default, only the nodes from the first terminal is used for the maximum current, matching the behavior of the “export capacity” command. Pass
allNodes=True
to force the analysis to all terminals.See also: https://sourceforge.net/p/electricdss/discussion/beginners/thread/da5b93ca/
- pctNormal(allNodes=False) altdss.types.Float64Array #
For each element in the batch, calculate the maximum current across the conductors as a percentage of the normal ampere rating.
By default, only the nodes from the first terminal is used for the maximum current, matching the behavior of the “export capacity” command. Pass
allNodes=True
to force the analysis to all terminals.See also: https://sourceforge.net/p/electricdss/discussion/beginners/thread/da5b93ca/
- pctPerm: altdss.ArrayProxy.BatchFloat64ArrayProxy#
‘property(…)’
Percent of failures that become permanent.
DSS property name:
pctPerm
, DSS property index: 23.
- to_json(options: Union[int, dss.enums.DSSJSONFlags] = 0)#
Returns the data (as a list) of the elements in a batch as a JSON-encoded string.
The
options
parameter contains bit-flags to toggle specific features. SeeObj_ToJSON
(C-API) for more, orDSSObj.to_json
in Python.Additionally, the
ExcludeDisabled
flag can be used to excluded disabled elements from the output.
