Dear Dr.
Ray,
I have a querry regarding Matpower's OPF program that how its load flow
equations are considering the effect of slack bus generator? Say if bus no. 1
is the slack bus then OPF is considering Pg1 as one of the variable, then how
it becomes possible that Pg1 takes into account additional power to be injected
or taken out for overall balancing of the system.Thanks for providing a
platform to resolve the querries.K D Singh
