Extended Equal Area Criterion Revisited: A Direct Method for Fast Transient Stability Analysis
Energies, 2021 For transient stability analysis of a multi-machine power system, the Extended Equal Area Criterion (EEAC) method applies the classic Equal Area Criterion (EAC) concept to an approximate One Machine Infinite Bus (OMIB) equivalent of the system to find ...

Segmental equal area criterion for grid forming converter with current saturation
International Journal of Electrical Power & Energy SystemsPrevious research indicates that post-fault grid-forming (GFM) converters only work in current limiting control (CLC) mode. However, converters integrating the current saturation algorithm (CSA) can operate in both constant voltage control (CVC) and CLC ...

Transient Energy of an Individual Machine PART III: Newtonian Energy Conversion
IEEE Access, 2021 In this third paper, the fundamental mechanism of individual-machine transient stability is explained through Newtonian mechanics. The original Newtonian system with variant gravity is developed. This system is formed by a ball and the Earth. It is found

A PMU-based algorithm of synchronous generator stability prediction during a disturbance [PDF]
E3S Web of Conferences, 2021 A PMU-based algorithm of synchronous generator stability prediction is proposed and tested in the paper. The algorithm is based on the application of the equal area criterion for the following spaces: active power – load angle, active power – time.
