loadDescriptor.xml : Generic Load - acep-uaf/MiGRIDS GitHub Wiki

For inherited tags that have not been modified please see the componentDescriptorInterface.xml documentation.

If a tag is inherited, but has been modified or limited in its use it is denoted with an * in the title.

There are active tags that are implemented in the tool and inactive tags that are not implemented but allow for future expansion and added functionality.

Active tags

minSRC tag

The minSRC tag is the fraction of the load that is the minimum coverage of Spinning Reserve required when this load is supplied in the grid.

Attributes:

value: 0.15 pu.

unit: the units are per unit of the load, PU.

Inactive tags

childOf tag*

The childOf tag names the direct parent. For the loadDescriptor implementation this is componentDescriptorInterface.

type tag*

The of load is always sink even if small discharges from capacitors or inductors are possible.

isDiscrete tag

This is a boolean tag describing if the load levels are discrete or continuous.

Attributes:

value: TRUE if load levels are discrete. Default value TRUE.

discreteLoadLevels tag

This tag is a bin for the available discrete load levels (see children).

Attributes:

pqIdpnt: TRUE if real and reactive power levels can switch independently. Default value is TRUE.

p and q tags

Real (p) and reactive (q) load levels available. These tags are organized in tuples of p and q. However, they only have to be regarded as dependent pairs if the attribute pqIdpnt of the parent element discreteLoadLevels is TRUE. Each tag has a value attribute with default value 0, and a unit attribute with units of kW and kvar for p and q respectively.

switchTime tag

This tag describes the typical time it takes for the unit to switch to the commanded load level from receipt of command (does not include network communications latencies).

Attributes:

value: the switching time. Default is 1000.

unit: the units are milliseconds (ms).

switchTimeDev tag

This tag describes the typical deviation around the switch time (see switchTime tag).

Attributes:

value: the typical time deviation. Default is 500.

unit: the units are milliseconds (ms).
