The iterative process is stopped when all stopping criterion
is met. The Path Study Tool has been setup to end all
iterations when pre-contingency and post-contingency flows are within 99.5% and 100% of normal and emergency ratings respectively and when all voltage deviations are within 0.5% of the respective limits for single line contingencies and double line contingencies. These are included in the study parameters file so that they can be adjusted as needed.
Fig.4 shows a detailed flow chart of the comprehensive framework developed to implement an automated path study tool.
