NonlinearShuntCompensator has ambiguity where NonlinearShuntCompensator class has description where it says: "The attributes g, b, g0 and b0 of the associated NonlinearShuntCompensatorPoint describe the total conductance and admittance of a NonlinearShuntCompensatorPoint at a section number specified by NonlinearShuntCompensatorPoint.sectionNumber." This describes total admittance model. In NonlinearShuntCompensatorPoint.b there is this note: "Positive sequence shunt (charging) susceptance per section." This describes additive admittance model. These two notes are contradictory. NonlinearShuntCompensatorPoint should be aligned with NonlinearShuntCompensator. Additive admittance model cannot model variable shunt reactor where admittance is decreasing with increasing section which is problem for conductance (negative conductance is not possible to enter).
