InterruptibleStandardLoad

Package: PowerOperationsOpenAPIModels · Source: Operations/StaticInjection/InterruptibleStandardLoad.json

An interruptible, voltage-dependent ZIP load whose demand can be curtailed through demand response programs, subject to an interruption cost.

Like StandardLoad, it breaks the ZIP into three pieces: Z (constant impedance), I (constant current), and P (constant power), according to P = P_P * V^0 + P_I * V^1 + P_Z * V^2 for active power and Q = Q_P * V^0 + Q_I * V^1 + Q_Z * V^2 for reactive power. (Voltage V is in per unit.) Unlike StandardLoad, it carries an operation_cost for interrupting the load.

For a non-interruptible ZIP load, see StandardLoad. For an interruptible constant-power load, see InterruptiblePowerLoad.

Properties

`id`	`integer`	yes	—	Unique integer identifier for this component.
`name`	`string`	yes	—	Name of the component. Components of the same type (e.g., `InterruptibleStandardLoad`) must have unique names, but components of different types (e.g., `InterruptibleStandardLoad` and `ACBus`) can have the same name.
`available`	`boolean`	yes	—	Indicator of whether the component is connected and online (`true`) or disconnected, offline, or down (`false`). Unavailable components are excluded during simulations.
