This model corresponds to ACdqo.Capacitor, but uses a different determination of the coefficients.
Instead of b and g the parameters y_abs and cos(phi) are used.
y = Y / G_base y_abs = |y| g = real(y) = |y|*cos(phi) conductance b = imag(y) = |y|*sin(phi) admittance dqo-components
No phase to phase capacitance.
