Improvement of Power System Transient Stability Using Optimal Control: Bang-Bang Control of Reactance
N. Ratmarao,Daniel K. Reitan +1 more
TL;DR: In this article, the problem of restoring a power system to its initial steady state in minimum time after a transient disturbance is identified as a minimum time problem in optimal control theory, and the optimal control obtained to achieve this objective, by use of Pontryagin's maximum principle, is bang-bang control of line reactance.

The Transient-Energy Method of Calculating Stability
TL;DR: In this paper, the transient-energy method is used to check and quantitatively evaluate the transient stability of a system of three or possibly more synchronous machines, where each machine is represented by a constant-magnitude voltage behind a fixed reactance (usually the transient reactance) and all losses and nonsynchronous loads are assumed to be constant throughout the transient.
