Aiming at the disadvantages of converting traditional transient stability margin into power system control measures, this paper proposes a new transient stability margin characterization method based on critical cutset transient stability available capacity (TATC). Compared with traditional transient stability margin based on fault clearance time or transient energy function, TATC can directly reflects power system transient stability margin form the view of power which is more conducive for power system planning and operation personnel to grasp system transient stability state, at the same time, is also advantageous for prevention measures and emergency control measures to be developed directly according TATC. Simulation results based on IEEE50 machine 145 bus system show that the proposed TATC can effectively characterize power system transient stability margin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
