Parameters of a Phase-Locked Loop (PLL) based on Kaura, Vikram, and Vladimir Blasko. "Operation of a phase locked loop system under distorted utility conditions." IEEE Transactions on Industry applications 33.1 (1997): 58-63.

Arguments

• ω_lp::Float64: PLL low-pass filter frequency (rad/sec), validation range: (0, nothing)
• kp_pll::Float64: PLL proportional gain, validation range: (0, nothing)
• ki_pll::Float64: PLL integral gain, validation range: (0, nothing)
• ext::Dict{String, Any}
• states::Vector{Symbol}: The states of the KauraPLL model are:

vd_pll: d-axis of the measured voltage in the PLL synchronous reference frame (SRF),
vq_pll: q-axis of the measured voltage in the PLL SRF,
ε_pll: Integrator state of the PI controller,
θ_pll: Phase angle displacement in the PLL SRF

• n_states::Int: KauraPLL has 4 states
