Power Flow Problem Formulation
Dr. Dan Tylavsky
Without knowledge of PLoss, PG cannot be determined a priori & vice versa.
Defn: Distributed Slack Bus - Losses to the system are supplied by several generators.
Defn: Slack Bus - That generator bus at which losses to the system will be provided. (Often the largest bus in the system.)
Solution is slightly slower to converge than polar form but, it is possible to construct a non-diverging iterative solution procedure.
(Important: When on VAR limits, the PV bus equations are the same as the PQ bus equations)
