Fast assessment of the effect of preventive wide area emergency control

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


This paper describes an approach to quick assessment of the effect that a suggested countermeasure would have on the system generators stability margins in respect to aperiodic rotor angle small signal stability. The approach ensures that computational demanding simulations can be avoided to determine whether the suggested counteraction is sufficient to avoid system instability during severely critical operating conditions. The fast assessment of the effect that a
countermeasure has on system stability provides an important decision support for the control room personnel in emergency situations. The validity of the suggested approach is proved on the 8 bus test system and IEEE30 bus test system.
