Operación diaria del sistema
Las operaciones de energía (PowerOps) y los operadores de
autoridades para el balance (BAO, por sus siglas en inglés)
son los grupos principales que participan en la operación
diaria del sistema de la empresa de servicios públicos. Hay
dos funciones de las PowerOps: la programación con un día
de antelación y la programación en tiempo real. La función
de programación con un día de antelación emplea una herra-
