Evaluación de la operación en isla de sistemas eléctricos de potencia mediante teoría de grafos

Abstract

This article deals with the analysis of islands that are generated in an electrical power system, due to faults that may exist in it. Graph theory will be used through a BFS (Breadth First Search) search algorithm in order to find the number of isolated areas, through the route of the entire circuit, with some sections being radial and mostly meshed, because their difficulty of analysis is closer to reality respect to the electric power networks that currently exist. Following the analysis of the number of registered islands, the characteristics of each island will be defined and thus consider whether each island can operate or not, taking into account the operating limits of a synchronous generator, as is the active power respectively and maintain the balance between generation and demand. The data exchange will be carried out between Digsilent Powerfactory and Matlab, which will define the most important parameters and variables to resolve the cases presented in the 39 and 118 bar models of the IEEE.
