Voltage stability is a major concern in the planning and operation of electric power systems. This book provides a clear, in-depth explanation of voltage stability, covering both transient and longer-term phenomena and presenting proven solutions to instability problems. The book describes equipment characteristics for transmission, generation, and distribution/load subsystems of a power system, together with methods for the modelling of equipment. Readers will find static and dynamic computer simulation examples for small equivalent power systems and for a very large power system, plus an account of voltage stability associated with HVDC links. They will also get helpful planning and operating guidelines, computer methods for power flow and dynamic simulation, and descriptions of actual voltage instability incidents.read more

IEEE recommended practice for excitation system models for power system stability studies
TL;DR: The model structures presented are intended to facilitate the use of field test data as a means of obtaining model parameters and do not represent all of the control loops on any particular system.

Small-Signal Methods for AC Distributed Power Systems–A Review
TL;DR: In this article, a review of small-signal analysis for AC distributed power systems can be found in several new and emerging applications, and the compatibility of each type of models with state-space and impedance-based system analysis approaches is discussed.

Use of local measurements to estimate voltage-stability margin
TL;DR: In this article, a new data processing method is proposed to estimate the proximity to voltage collapse in real-time, which employs only local measurements-bus voltage and load current-and calculates the strength of the transmission system relative to the bus.
