Reduced Order DFIG Models for PLL-Based Grid Synchronization Stability Assessment
IEEE Transactions on Power Systems, 2023This paper presents a reduced-order modeling approach to study the grid synchronization stability of type-3 wind turbine generator (WTG) by considering the dynamics of the phase-locked loop (PLL) alone.

An Optimization-Based Method for Transient Stability Assessment
IEEE Conference on Decision and Control, 2023The paper proposes an optimization-based method for the transient stability assessment of lossy multi-machine power systems. To achieve this objective, a global control Lyapunov function candidate including an auxiliary state is introduced. On this basis,

Direct Transient Stability Assessment with Excitation Control
IEEE Power Engineering Review, 1989The authors extended the applicability of the transient energy function method by incorporating the exciter effects in the energy of a multimachine power system during the first swing transient. The generator was represented by the two-axis model and the exciter was represented by one gain, one time constant, and one limiter. In this study they compute

A Physics-Informed Deep Learning Paradigm for Transient Power Angle Stability Assessment
IEEE Journal of Radio Frequency Identification, 2022Transient stability assessment (TSA) plays an essential role in the safe and stable operation of power system. The traditional time-domain simulation method and direct method have great limitation in modeling and computing, which can not meet the need of

A mixed direct method for transient stability assessment
Journal of the Chinese Institute of Engineers, 1993Abstract A mixed direct method taking the advantages of both the potential energy boundary surface (PEBS) method and the extended equal area criterion (EEAC) method for transient stability analysis of multimachine power systems with detailed models is presented.

Gait & Posture, 2015
For maintaining heading direction while walking we heavily rely on vision. Therefore, walking in the absence of vision or with visual attention directed elsewhere potentially leads to dangerous situations. Here we investigated whether tactile information from the feet can be used as a (partial) substitute for vision in maintaining a stable heading ...

A fast accurate method for direct assessment of transient stability
26th IEEE Conference on Decision and Control, 1987A direct stability assessment method that can act as a fast screening tool for determining retention or loss of stability is becoming of increasing interest in system planning, operation planning and on-line control center applications. In this paper, a fast, accurate method for determining retention or loss of stability without requiring time ...

Direct Methods of Stability Analysis in Dynamic Security Assessment
IFAC Proceedings Volumes, 1984Abstract Direct methods of stability analysis have been intensely investigated over the past two decades and are now found practicable in obtaining accurate critical breaker clearing times for a given fault. Obtaining this information on-line is only an indirect way of ascertaining robustness of the system.
