A voltage-dependent ZIP load, most commonly used for dynamics modeling.

An ExponentialLoad models active power as P = P0 * V^α and reactive power as Q = Q0 * V^β, where the exponents α and β select govern the voltage dependency. For an alternative three-part formulation of the ZIP model, see StandardLoad. For a simpler load model with no voltage dependency, see PowerLoad

Arguments

  • name::String: Name of the component. Components of the same type (e.g., PowerLoad) must have unique names, but components of different types (e.g., PowerLoad and ACBus) can have the same name
  • available::Bool: Indicator of whether the component is connected and online (true) or disconnected, offline, or down (false). Unavailable components are excluded during simulations
  • bus::ACBus: Bus that this component is connected to
  • active_power::Float64: Active power coefficient, P0 (MW)
  • reactive_power::Float64: Reactive power coefficient, Q0 (MVAR)
  • α::Float64: Exponent relating voltage dependency for active power. 0 = constant power only, 1 = constant current only, and 2 = constant impedance only, validation range: (0, nothing)
  • β::Float64: Exponent relating voltage dependency for reactive power. 0 = constant power only, 1 = constant current only, and 2 = constant impedance only, validation range: (0, nothing)
  • base_power::Float64: Base power (MVA) for per unitization, validation range: (0.0001, nothing)
  • max_active_power::Float64: Maximum active power (MW) that this load can demand
  • max_reactive_power::Float64: Maximum reactive power (MVAR) that this load can demand
  • conformity::LoadConformity: (default: LoadConformity.UNDEFINED) Indicates whether the specified load is conforming or non-conforming. Options are listed here.
  • services::Vector{Service}: (default: Device[]) Services that this device contributes to
  • dynamic_injector::Union{Nothing, DynamicInjection}: (default: nothing) corresponding dynamic injection device
  • ext::Dict{String, Any}: (default: Dict{String, Any}()) An extra dictionary for users to add metadata that are not used in simulation.
  • internal::InfrastructureSystemsInternal: (Do not modify.) PowerSystems.jl internal reference
