System and method of synchronous aggregate control of a power plant with multiple conversion stations that regulates the active and reactive power supplied to the power grid (3) through a virtual synchronous control strategy that has a two-level structure. A central control (6) that has the ability to provide support in frequency and voltage by means of the electromechanical characteristic of the synchronous machine, and a local control (11) that is responsible for defining the levels of active and reactive power in each conversion station (two). This control method assists the stability of the network through frequency and voltage support by dynamically distributing the power levels required by each conversion station by means of a charging angle (20) and the voltage amplitude of the electromotive force (21) .

Un control central (6) que tiene la capacidad de proveer soporte en frecuencia y tensión mediante la característica electromecánica de la máquina síncrona, y un control local (11) que se encarga de definir los niveles de potencia activa y reactiva en cada estación de conversión (2). Este método de control asiste a la estabilidad de la red mediante el soporte en frecuencia y tensión distribuyendo dinámicamente los niveles de potencia requeridos por cada estación de conversión mediante un ángulo de carga (20) y la amplitud de tensión de la fuerza electromotriz (21).
