HybridOutputCurrentLimiter

PowerSystems.HybridOutputCurrentLimiterType
mutable struct HybridOutputCurrentLimiter <: OutputCurrentLimiter
    I_max::Float64
    rv::Float64
    lv::Float64
    ext::Dict{String, Any}
end

Parameters of Hybrid Current Controller Limiter. Regulates the magnitude of the inverter output current, but with a closed loop feedback regulated by a virtual impedance which provides ant-windup. Described in: Novel Hybrid Current Limiter for Grid-Forming Inverter Control During Unbalanced Faults by Baeckland and Seo, 2023

Arguments

  • I_max::Float64: Maximum limit on current controller input current (device base), validation range: (0, nothing)
  • rv::Float64: Real part of the virtual impedance, validation range: (0, nothing)
  • lv::Float64: Imaginary part of the virtual impedance, validation range: (0, nothing)
  • ext::Dict{String, Any}: (default: Dict{String, Any}())
