This paper presents a new transient stability index based on the implicit expression for the stability region boundary and an approximation of the proposed index based on the quadratic approximation of the stability region.

Based on angle and angular speed of each generator,an extended d -Ek energy phase plane is proposed in this paper, and on the basis of trajectory information of extended d -Ek energy phase plane of each generator a transient stability index of generator is put forward, then a corresponding analysis method adopting curve fitting is given.

The stability of the transient dynamics is evaluated with the transient stability margin index based.

A new approach to solve the stability-constrained optimal power flow (SCOPF) based on a novel transient stability margin index and its sensitivities is proposed.
