This paper presents an algorithm oriented to improve the security conditions of electric power systems. The proposed algorithm performs a semi-exhaustive search of the possible configuration of the system substation with the objective of minimizing overloads presented in single contingencies (N-1 criterion). Topological modifications are made by changing the state of switches in substations. Results are presented for the IEEE 118 bus test system showing the effectiveness of the proposed algorithm.
En este artículo se presenta un algoritmo orientado a mejorar las condiciones de seguridad de los sistemas de potencia. El algoritmo propuesto realiza una búsqueda semi-exhaustiva de posibles configuraciones de subestaciones con el objetivo de minimizar las sobrecargas presentadas ante contingencias simples (criterio N-1). Las modificaciones topológicas se hacen a través del cambio de los estados de los interruptores en las subestaciones. Se presentan resultados para el sistema IEEE de 118 barras que evidencian la efectividad del algoritmo propuesto.
