An interactive visual enviroment based on advanced numerical and computer techniques for power systems applications

This contribution details the application of a developed interactive visual environment for power system analysis. In principle, it is based on a methodology to obtain the numerical solution of the Ordinary Differential Equations (ODEs) that represent the dynamic behavior of power systems. The methodology relies on the application of Object Oriented Programming (OOP) techniques, so that power system components can be represented as objects, which are later used as functional blocks, facilitating the representation of a system of any type of complexity. Parallel Programming (PP) techniques are also applied in order to fully exploit the capabilities of new micro-processors of executing more than one process simultaneously, with the aim of reducing the simulation time. Besides, the parallel evaluation scheme presented in this paper has shown to be effective and can be easily adapted to any other numerical integration method without the need to modify the numerical algorithm. Case studies are presented which demonstrate the effectiveness of the proposed interactive digital tool and the methodology for power system analysis.
