Converging the Power Flow, Part 2
Reasons for divergence, and our explanations.
The power system is going to “blow-up.” — the term “blow-up” just applies to the numerical solution.
There is something wrong with the solution algorithm. — not the formulation but perhaps the implementation into computer code.
There is something wrong with the data. — yes, of course. The old concept – garbage in, garbage out.
There is something wrong with my computer. — do you have a 386?
The solution hit a bad iteration. — like hitting a crack in the pavement that breaks your differential and off goes the wheel! Not a bad analogy except that its much easier to do the bad iteration than it is to break the car.
We hit a bifurcation. — yes, after we exclude all the other simple reasons.
We hit a saddle-node bifurcation. — even better.
We hit the wall. — like, “this software is driving me crazy, I want to hit my head against the wall?” Continue reading

Oct 2009 Power Flow Analysis and Applications Course
Held in Albany, NY, Sept 29-Oct 1, 2009
We have to look back on how many times this course has been held, but this remains a popular topic. This time around the attendees came from the New York ISO, ISO New England and the Midwest ISO. (ISO – independent system operator, for our overseas friends).
Student Comments
The average course rating by the participants was 5.0 on a scale of 5. Some of the participant comments:
•Excellent instructors. Responsive to questions, shared experience and knowledge and examples.
•Very logical structure of course progression and presentation – easy to follow and learn
•Being quite new, I appreciate the “hand-holding” during exercises and discussions.
•I learned a lot. Small class size was helpful.
•Knowledgeable and friendly staff!
•Excellent experience – thank you!
