An Iterative Approach to Calculating Dynamic ATC
نویسندگان
چکیده
Stability limits place restrictions on the available transfer capability (ATC) of power systems. Calculation of these limits is therefore very important, but has traditionally been quite difficult. This paper proposes an iterative algorithm for determining parameter values which result in marginal stability of a system. (A system is marginally stable for a particular disturbance if the postdisturbance trajectory lies on the stability boundary.) A knowledge of the critical parameter values allows the dynamic ATC to be determined. The algorithm is based on the Gauss-Newton solution of a nonlinear least-squares problem. This solution process uses trajectory sensitivities.

In this study, a hybrid method is proposed to investigate the nonlinear vibrations of pre- and post-buckled rectangular plates for the first time. This is an answer to an existing need to develope a fast and precise numerical model which can handle the nonlinear vibrations of buckled plates under different boundary conditions and plate shapes. The method uses the differential quadrature element...
