A TEMPLATE SPARSE LIBRARY FOR POWER SYSTEMS

Amrane Tolba – Louiza Benfarhi –Mohamed Belkacemi

   This paper present a Template Sparse Library for Power Systems (TSLPS) developed in C++. Its aim is to provide a coherent platform for many power system applications such as Load Flow(LF), Short Circuit(SC), Optimal Power Flow(OPF) and Transient Stability (TS). The TSLPS is inspired by the recent template numerical library but considers only power system characteristics, eg for a class of large sparse symmetric matrices over real and complex numbers. Template facility of C++ is used to write a generic program on float, double and complex data types. The paper describes the generic code developed and its impact on the power system applications. LF and SC analysis have been successfully applied to the solution of several power systems and presented good computational performance.

Keywords: power systems, sparse matrix, template, LU decomposition, object oriented programming
