A dynamic inverter with the necessary data for modeling the dynamic response of an inverter in a phasor or electromagnetic transient simulation.

A dynamic inverter is composed by 6 components, namely a Converter, Outer Loop Control, Inner Loop Control, a DC Source, a Frequency Estimator and a Filter.

It must be attached to a StaticInjection device using add_component!, which contains all the rest of the generator's data that isn't specific to its dynamic response.

Arguments

• name::String: Name of inverter.
• ω_ref::Float64: Frequency reference set-point in pu.
• converter <: Converter: Converter model for the PWM transformation.
• outer_control <: OuterControl: An OuterControl controller model.
• inner_control <: InnerControl: An InnerControl controller model.
• dc_source <: DCSource: DCSource model.
• freq_estimator <: FrequencyEstimator: a FrequencyEstimator (typically a PLL) model.
• filter <: Filter: Filter model.
• limiter <: Union{nothing, OutputCurrentLimiter}: (default: nothing) Inner Control Current Limiter model
• base_power::Float64: (default: 100.0) Base power of the unit (MVA) for per unitization. Although this has a default, in almost all cases base_power should be updated to equal the base_power field of the StaticInjection device that this dynamic generator will be attached to.
• n_states::Int: (Do not modify.) Number of states (will depend on the inputs above).
• states::Vector{Symbol}: (Do not modify.) Vector of states (will depend on the inputs above).
• 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
