An infinite bus with a constant voltage output.

Commonly used in dynamics simulations to represent a very large machine on a single bus or for the representation of import/exports in operational simulations

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: The ACBus that this component is connected to
• active_power::Float64: (default: 0.0) Initial active power set point of the unit in MW. For power flow, this is the steady state operating point of the system. For production cost modeling, this may or may not be used as the initial starting point for the solver, depending on the solver used
• reactive_power::Float64: (default: 0.0) Initial reactive power set point of the unit (MVAR)
• active_power_limits::MinMax: (default: (min=0.0, max=0.0)) Minimum and maximum stable active power levels (MW)
• reactive_power_limits::Union{Nothing, MinMax}: (default: (min=0.0, max=0.0)) Minimum and maximum reactive power limits. Set to Nothing if not applicable
• R_th::Float64: (default: 0.0) Source Thevenin resistance. See here:, validation range: (0, nothing)
• X_th::Float64: (default: 0.0) Source Thevenin reactance. See here:, validation range: (0, nothing)
• internal_voltage::Float64: (default: 1.0) Internal Voltage (pu), validation range: (0, nothing)
• internal_angle::Float64: (default: 0.0) Internal Angle
• base_power::Float64: (default: 100.0) Base Power in MVA
• operation_cost::ImportExportCost: (default: ImportExportCost(nothing)) ImportExportCost of the source.
• dynamic_injector::Union{Nothing, DynamicInjection}: (default: nothing) corresponding dynamic injection device
• services::Vector{Service}: (default: Device[]) Services that this device contributes to
• 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
