Abstract: In recent decades, several improvements have been achieved in power system operation and control. The evolution was mainly in the development of computational and communication systems. Both areas allowed the analysis of complex models of power system operation and control that resulted in a more flexible system controlled in almost real-time mode. All these improvements favoured the change of power system operation to a new environment, in which the traditionally electrical energy system-regulated monopoly became deregulated with operations based on energy market operations. In this environment, not only security, but also the monitoring of power flow direction and the controls, represent critical issues. This paper presents an overview on the real-time monitoring and control in power systems.
Keywords: electric power systems; real-time modelling; real-time control; security analysis; reliability.
