Identificación de Áreas de Control de Voltaje en el Sistema Nacional Interconectado de Ecuador utilizando Minería de Datos

Abstract

This paper presents a new methodology in order to identify the Voltage Control Areas VCA in a power system. Each VCA is constituted by a group of system buses exhibiting similar voltage behavior patterns when the power system is subjected to perturbations that could originate voltage instability problems. Once identified the VCA, the system operator can perform proper coordinated control and supervisory strategies in order to improve the voltage behavior in these buses. In this sense, the electrical distance concept has been used in order to identify the VCA using a new methodology based on data mining. The methodology has been applied in order to identify the VCA of the National Interconnected System of Ecuador SNI; this will establish the monitoring and control strategies by the National Electricity Operator CENACE in the SNI and improve the system security.
