| Abstract | This paper presents a strategy to implement transient stability constrained optimal power flow in cascading outages. Anticipatory computing detects transient instability due to weakened system conditions in cascading progressions and prepares transient stability constraints for optimal power flow. The prepared constraints use trajectory sensitivities, which can speed up the analysis by estimating rotor angle response changing with generation levels. The proposed strategy has been tested on a 140-bus, 48-machine system. |
