Application of Vectorization Technology in High Performance Calculation of Power System

Vectorization technology can be applied in the power system computation to improve the executive speed and reduce the complexity of the modeling and implementation. The basic principle of vectorization technology and its application in high performance scientific calculation are introduced in this paper. The vectiorization formulas of power flow calculation in both Cartesian coordinate and polar coordinate are deduced to demonstrate its applicability in the modeling and algorithm implementation of power system. The vectorization calculation library is designed and implemented, based upon which a vectorization implementation of optimal power flow (OPF) program is developed. Simulations of this OPF program show that vectorization improves the executive speed considerably. A solution for the development of vectorial power system program is presented, which shorten the development cycle of high performance program and accelerates the applicability of various algorithms.
