Abstract
An electrical accumulator unit wherein an energy storage device is utilized in conjunction with an actively controlled bidirectional power converter to provide auxiliary power to an electrical network is disclosed.
Claims23
A device for providing auxiliary power to an electrical network comprising:
- an energy storage device;
- and
- an actively controlled power converter coupled in parallel to said electrical network and operatively coupled to the energy storage device;
- wherein said actively controlled power converter is configured to provide automatic bidirectional power flow into and out of the electrical network from and to, respectively, the energy storage device in response to at least one measured electrical property within the electrical network.
