Title
(EN) ENERGY STORAGE SYSTEMS WITH ENNHANCED STORAGE AND DISCHARGE RESPONSE ALLOCATION
(FR) SYSTÈMES DE STOCKAGE D'ÉNERGIE AVEC STOCKAGE ET ATTRIBUTION DE RÉACTION DE DÉCHARGE AMÉLIORÉS
Abstract
(EN)
In one embodiment, an energy storage system includes a plurality of energy storage banks. The plurality of energy storage banks include a first set of one or more energy storage banks and a second set of one or more energy storage banks. The first set of the energy storage banks is associated with a faster charge/discharge rate relative to the second set of energy storage banks. The energy storage system includes at least one control device that is configured to control the first set of energy storage banks to accept or discharge energy in response to fluctuations in a power signal associated with a first frequency; and is further configured to control the second set of energy storage banks to accept or discharge energy in response to fluctuations in the power signal associated with a second frequency. The first frequency is greater than the second frequency.

Dans un mode de réalisation de l'invention, un système de stockage d'énergie contient une pluralité de banques de stockage d'énergie. La pluralité de banques de stockage d'énergie comprend un premier ensemble d'une ou de plusieurs banques de stockage d'énergie et un deuxième ensemble d'une ou de plusieurs banques de stockage d'énergie. Le premier ensemble de banques de stockage d'énergie est associé à une vitesse de charge/décharge plus rapide par rapport au deuxième ensemble de banques de stockage d'énergie. Le système de stockage d'énergie contient au moins un dispositif de commande qui est configuré pour commander le premier ensemble de banques de stockage d'énergie pour qu'il reçoive ou décharge de l'énergie en réponse à des fluctuations dans un signal d'alimentation associé à une première fréquence; et il est aussi configuré pour commander le deuxième ensemble de banques de stockage d'énergie pour qu'il reçoive ou décharge de l'énergie en réponse à des fluctuations dans le signal d'alimentation associé à une deuxième fréquence. La première fréquence est supérieure à la deuxième fréquence.
