Controlled energy storage balance technology
An energy storage system that comprises an energy reservoir and a system controller. The energy reservoir is charged by DC energy from a DC energy source while discharging DC energy to a DC/AC converter. A system controller regulates the DC energy discharged from the energy reservoir to the DC/AC converter to nearly balance the amount of DC energy charged into the energy reservoir. Because this charging and discharging is nearly balanced, the size of the energy reservoir can be made quite small relative to the amount of charging and discharging. This is advantageous where the flow of charge and discharge is high, as might be the case if the energy reservoir receives charge from all or a substantial portion of a power station, such as a solar power station. With such a controller, the use of an energy reservoir becomes technically feasible even with such large current flows. |
