Abstract
The present disclosure provides an energy storage system comprising at least one capacitive energy storage device and a DC-voltage conversion device. The capacitive energy storage device comprises at least one metacapacitor. The output voltage of the capacitive energy storage device is the input voltage of the DC-voltage conversion device. The capacitive energy storage system is capable of being charged from a power generation system and/or an electrical grid and discharging energy to a load and/or electrical grid. The capacitive energy storage system is configurable to supply external power as an operating power in a first state in which the external power is applied and/or to supply power as the operating power in a second state in which the external power is not applied.
