  Part II of this paper elaborates on the unique capability of the proposed
power flow analysis framework to obtain the true solution corresponding to the
stable operating point of a network. It explains the significance of obtaining
the true solution for an accurate assessment of the voltage collapse margin.
This feature distinguishes the framework from all iterative and non-iterative
heuristic approaches as demonstrated in the context of a 7-bus network with
Newton-Raphson, its variants and semidefinite and moment-based relaxations of
power flow. Another important feature of this framework is that it obtains the
true solution when it exists and declares its non-existence otherwise. This is
demonstrated in the context of small networks and in comparison with heuristic
approaches. This paper also explores how the proposed framework detects a
limit-induced bifurcation where a network controller reaching its limit can
initiate voltage collapse.
