US Patent:

20180041051, Feb 8, 2018

Filed:

Aug 8, 2016

Appl. No.:

15/230613

Inventors:

- Schenectady NY, US
Richard Scott Bourgeois - Albany NY, US
David Eugene James - Schenectady NY, US
Joshua Paul Webb - Schenectady NY, US
Mark Edward Gotobed - Schenectady NY, US

International Classification:

H02J 7/00

Abstract:

The present disclosure is directed to a system and method for controlling an energy storage system. The energy storage system includes a plurality of parallel-connected energy storage devices. The method includes determining, by one or more controllers, a limiting energy storage device based at least in part on a current rating for the limiting energy storage device. The method includes determining, by the one or more controllers, an adjusted allowable system current based at least in part on modifying one or more operational parameters of the limiting energy storage device. The method includes determining, by the one or more controllers, a modified operational parameter of the limiting energy storage device to increase the allowable system current of the energy storage system. The method includes controlling the limiting energy storage device based at least in part on the modified operational parameter.

Appl. No.:

15/186798

Inventors:

- Schenectady NY, US
Kenneth McClellan Rush - Ballston Spa, NY
Joshua Paul Webb - Schenectady NY, US
Richard Scott Bourgeois - Albany NY, US

International Classification:

H02J 7/34

Abstract:

Systems and methods for controlling power distribution are provided. The method includes receiving a power command, wherein the power command requests a discharge from one or more BESS units, and wherein the one or more BESS units are housed in one or more temperature controlled rooms. For each of the one or more temperature controlled rooms, a lowest energy remaining of the one or more BESS units in the temperature controlled room is determined; a low threshold is determined based on the determined lowest energy remaining and a floor; a limit is determined based on the determined low threshold; and the limit is assigned to each of the one or more BESS units housed in the temperature controlled room. The method includes causing the power command to be at least partially satisfied by the one or more BESS units based on the assigned limits.

International Classification:

H01M 10/657
H01M 10/0525
H01M 10/30
H01M 10/42

Abstract:

Systems and methods for controlling the temperature of an energy storage system are provided. More specifically, a time period of increased battery temperature attributable to, for instance, charging or discharging of the battery can be identified. A control system can be used to reduce the ambient temperature of a space associated with the battery energy storage devices in the time period prior to or immediately before the period of increased battery temperature. The ambient temperature can be maintained at a nominal ambient temperature at other times.

Abstract:

Systems and methods for controlling an energy storage system to provide for delivery of multiple grid services are provided. Grid service requests can be categorized into a plurality of priority tiers. Power demands associated with the grid service requests can be allocated to enforce the prioritization scheme of the priority tiers. For instance, power demands associated with grid service requests in higher priority tiers can be given preference over power demands associated with grid service requests in lower priority tiers. Multiple grid service requests can be categorized within the same priority tier. In addition, the energy storage system can be controlled not only give priority to grid services requests categorized in the higher priority tiers, but also to manage the state of charge of the system to ensure that there is sufficient reserve capacity to meet power demands of the grid service requests categorized in the higher priority tiers.
