Research output: Contribution to journalArticlepeer-review


This paper discusses several of the practical and theoretical issues associated with the dynamic vs. static issues of voltage problems. It focuses mainly on the issues of maximum loadability and the avoidance of non-physical models. It concludes with the proposition that static analysis normally produces optimistic upper bounds on practical questions about loadability. Realistic bounds are obtained by a small disturbance analysis and even better with transient large disturbance analysis.
