El análisis de los eventos y las tendencias recientes de la
red en la operación del sistema demuestra que se necesitan
mejoras en la filosofía operativa actual, o incluso una nueva
filosofía, con el fin de garantizar la seguridad del sistema
eléctrico en un contexto de constante cambio. En esta sección analizamos elementos que tendrán un papel central en
un nuevo paradigma operativo exitoso.

La operación segura del sistema eléctrico requiere tomar
medidas rápidas y efectivas en condiciones críticas de la
red. Normalmente se muestran muchas alarmas en el gran
monitor del centro de control de un GRT en caso de que
haya un evento en la red. En algunos casos, los operadores
de sistemas deben procesar de manera visual esta información e identificar las alarmas más importantes. La aplicación de análisis e inteligencia artificial en los datos de monitoreo en tiempo real pueden ayudar a clasificar las alarmas
en primera prioridad (por ejemplo, alarmas asociadas con
el origen de un evento) y segunda prioridad (por ejemplo,
alarmas activadas como consecuencia de otras alarmas).
Tales métodos, junto con enfoques de visualización modernos que, por ejemplo, muestren las alarmas de acuerdo con
