begin_edit() → None#

Marks a DSS object for editing

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 and end_edit. For convenience, those are emitted automatically when editing single properties outside an edit block.

edit(**kwargs: typing_extensions.Unpack[altdss.GenDispatcher.GenDispatcherProperties]) → altdss.GenDispatcher.GenDispatcher#

Edit this GenDispatcher.

This method will try to open a new edit context (if not already open), edit the properties, and finalize the edit context. It can be seen as a shortcut to manually setting each property, or a Pythonic analogous (but extended) to the DSS Edit command.

Parameters:: **kwargs – Pass keyword arguments equivalent to the DSS properties of the object.
Returns:: Returns itself to allow call chaining.

end_edit(num_changes: int = 1) → None#

Leaves the editing state of a DSS object

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 the Action property is used with the Process value.

kWBand: float#

‘property(…)’

Bandwidth (kW) of the dead band around the target limit.No dispatch changes are attempted if the power in the monitored terminal stays within this band.

DSS property name: kWBand, DSS property index: 4.

kWLimit: float#

‘property(…)’

kW Limit for the monitored element. The generators are dispatched to hold the power in band.

DSS property name: kWLimit, DSS property index: 3.

kvarLimit: float#

‘property(…)’

Max kvar to be delivered through the element. Uses same dead band as kW.

DSS property name: kvarLimit, DSS property index: 5.

to_json(options: Union[int, dss.enums.DSSJSONFlags] = 0)#

Returns an element’s data as a JSON-encoded string.

The options parameter contains bit-flags to toggle specific features.

By default (options = 0), only the properties explicitly set. The properties are returned in the order they are set in the input. As a reminder, OpenDSS is sensitive to the order of the properties.

The options bit-flags are available in the DSSJSONFlags enum. Values used by this function are:

Full: if set, all properties are returned, ordered by property index instead.
SkipRedundant: if used with Full, all properties except redundant and unused ones are returned.
EnumAsInt: enumerated properties are returned as integer values instead of strings.
FullNames: any element reference will use the full name ({class name}.{element name}) even if not required.
Pretty: more whitespace is used in the output for a “prettier” format.
SkipDSSClass: do not add the “DSSClass” property to the JSON objects.

NOT IMPLEMENTED YET:

State: include run-time state information
Debug: include debug information

Other bit-flags are reserved for future uses. Please use DSSJSONFlags enum to avoid potential conflicts.

batch(**kwargs)#: 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.GenDispatcher.GenDispatcherBatchProperties]) → altdss.GenDispatcher.GenDispatcherBatch#

Creates a new batch of GenDispatcher objects

Either names, count or df 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 to end_edit() or equivalent. The default begin_edit is set to None. With None, 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 to True 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 to count. begin_edit defaults to True 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 to False.

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

edit(**kwargs: typing_extensions.Unpack[altdss.GenDispatcher.GenDispatcherBatchProperties]) → altdss.GenDispatcher.GenDispatcherBatch#

Edit this GenDispatcher batch.

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

find(name_or_idx: Union[AnyStr, int]) → altdss.DSSObj.DSSObj#: Returns an object from the collection by name or index; the index must be zero-based.

kWBand: altdss.ArrayProxy.BatchFloat64ArrayProxy#

‘property(…)’

Bandwidth (kW) of the dead band around the target limit.No dispatch changes are attempted if the power in the monitored terminal stays within this band.

DSS property name: kWBand, DSS property index: 4.

kWLimit: altdss.ArrayProxy.BatchFloat64ArrayProxy#

‘property(…)’

kW Limit for the monitored element. The generators are dispatched to hold the power in band.

DSS property name: kWLimit, DSS property index: 3.

kvarLimit: altdss.ArrayProxy.BatchFloat64ArrayProxy#

‘property(…)’

Max kvar to be delivered through the element. Uses same dead band as kW.

DSS property name: kvarLimit, DSS property index: 5.

new(name: AnyStr, *, begin_edit: Optional[bool] = None, activate=False, **kwargs: typing_extensions.Unpack[altdss.GenDispatcher.GenDispatcherProperties]) → altdss.GenDispatcher.GenDispatcher#

Creates a new GenDispatcher.

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 an end_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.

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. See Obj_ToJSON (C-API) for more, or DSSObj.to_json in Python.

Additionally, the ExcludeDisabled flag can be used to excluded disabled elements from the output.
