Abstract: A capacitor based energy storage system (CBESS) and methods of using it are disclosed. The CBESS uses meta-capacitors in its capacitive energy storage devices (CESD) to configure capacitive energy storage cells (CESC), which are used to configure capacitive energy storage modules (CESM) to achieve the CBESS's function as an uninterruptible power supply. The CBESS is connected to a power generation system (PGS), a load, and a power grid. When the grid is in an abnormal state, the CESM is simultaneously charged with power from the PGS and used to supply power to the load. If a remaining amount of power of a CESM is less than a predetermined level, the CESM is charged with power from PGS or grid. The CBESS interfaces with a computer system or network to buy or sell electricity to the grid depending on grid electricity cost and CESD charging states.
