POWER-SYSTEM MODELING AND SPARSE-MATRIX OPERATIONS USING OBJECT-ORIENTED PROGRAMMING

This paper reports on power system modelling and sparse matrix operations using object-oriented programming (OOP). It has been claimed that OOP leads to more flexible, modular and reusable code, and that programs can be written more general. The main focus of the paper is OOP design principles and practical implementations for power systems. Specific examples included demonstrate a power system model design, particularly focusing on OOP mechanisms and object-oriented style of programming. Also demonstrated, using OOP, are tailor-made sparse matrix storage schemes and operations. Numedcal tests indicate that the proposed design is efficient compared to standard numerical library routines and that the particular OOP features that are used to obtain flexibility etc. do not significantly increase computation time.
