Abstract :
The increase in power transfer among areas of interconnected power systems and the reduction of reactive power reserves together with the competition in the electricity markets, force system operators and planners to look at the determination of the available transfer capability (ATC) of the system in a new perspective. In particular, a (N-1) security approach should be adopted in the determination of the ATC. In this paper, second order information derived from the singular value decomposition of the load flow (LF) Jacobian matrix is combined with an iterative procedure in order to obtain a suitable estimation of the ATC by means of a linear programming procedure. The effectiveness of the presented approach is supported by the tests on the IEEE 73 buses reliability test system and on the Italian EHV transmission system
