Description Simulation of the transient stability problem, which is the assessment of the short term (several to 30 seconds) angular and voltage stability of the power system following a disturbance, is of vital importance. For some portions of the North American power grids, such as the Western Electric Coordinating Council (WECC), transient stability has always been an important consideration...

Real-time assessment of transient stability is one of the main issues of power system operators in online applications. This paper proposes a novel recursive approach based on corrected kinetic energy which has the capability of real-time assessment and real time computation of transient stability margin in the power system. This approach considers all details of power system by using network p...

With increased power transfer, transient stability is increasingly important for secure operation. Transient stability evaluation of large scale power systems is an extremely intricate and highly non-linear problem. An important function of transient evaluation is to appraise the capability of the power system to withstand serious contingency in time, so that some emergencies or preventive cont...

facts technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. statcom is oneof the most important facts devices used in the parallel compensation, enhancing transient stability andetc. since three phase fault is widespread in power systems, in this paper statcom is used...

This paper proposes a Principal Component Analysis (PCA)-based method to construct composite indices rapidly assess power system transient stability. By assigning appropriate weights few selected sub-indicators, index can be constructed guarantee better coverage of worst-case stability scenarios the system. provides an automatic with four sub-indicators calculated by integral acceleration, spee...
