Implementación de una herramienta para la evaluación de la seguridad dinámica en línea del Sistema Nacional Interconectado usando simulación digital en tiempo real.

Abstract

Today's power system operating environment is becoming more complex. The introduction of new technologies and the high penetration of non-conventional renewable energies make the analysis of the dynamic security of the system more important. On-line dynamic security assessment (DSA) consists of assessing the ability of the power system to support a set of defined contingencies and reach a new acceptable steady state. This computational analysis is performed in quasi-real time considering voltage stability (VSA) and transient stability (TSA) aspects for the current operating point of the system. The present work focuses on implementing an on-line DSA analysis tool applied to the National Interconnected System of Ecuador (S.N.I) using a real-time digital simulator as a high-performance computational tool. To achieve this objective, a methodology has been implemented to acquire data in quasi-real time from CENACE's SCADA/EMS and integrate it with computational tools. With the simulation results, performance indicators have been developed to evaluate the voltage and transient stability, allowing to determine the dynamic security level of the S.N.I for the current operating condition.
