Implementation of network sensitivity calculation on vector computers

Abstract

A vector implementation of sensitivity computation that can be used in the remedial action planning of N‐1 steady state security assessment function is presented in this paper. In order to exploit the power of vector processors, the formulations of sensitivity calculation are restructured to minimize the execution time and the effects of data storage scheme are investigated. Tests of the proposed schemes are conducted on Alliant FX/80 and Convex 3840 machines. Test results have shown that the execution time required for obtaining a large set of sensitivity factors can be greatly reduced by using the proposed schemes on vector computers.

Key words:

• sensitivity matrix
• vector computer
• security analysis
