18.1 Introduction

With each passing year, the operation of electric power systems experiences several technical challenges associated with the new paradigms of management and planning such as the inclusion of deregulated markets, the interconnection with neighboring regional systems, the diversification of energy sources, the inclusion of environmental restrictions, and even the massive penetration of nonconventional generation plants. Under these conditions, security and reliability can be seriously compromised since unexpected disturbances may cause violations to the security limits established for the electric power system leading to the outage of important system elements and even partial or total blackouts [1].

Real time supervision of the static and dynamic security of the power system plays a fundamental role inside the applications used in control centers. The main purpose of real time monitoring is to present an early warning to the system operators so they can execute adequate control actions and thus mitigate ...
