Abstract

A controller for an electric power storage device is described herein, wherein the electric power storage device is included in a microgrid. The electric power storage device has at least one of a charge rate, a discharge rate, or a power retention capacity that has been customized for a collective microgrid. The at least one of the charge rate, the discharge rate, or the power retention capacity of the electric power storage device is computed based at least in part upon specified power source parameters in the at least two connected microgrids and specified load parameters in the at least two connected microgrids.

Claims5

Dependent claims

A microgrid system, comprising:

a controller comprising a control algorithm comprising a customized profile for at least one parameter of an electric power storage device included in the microgrid system;
wherein the at least one parameter is one of electric power storage capacity, charge rate, or discharge rate;
wherein the control algorithm dynamically controls the at least one parameter during microgrid operation;
wherein the at least one parameter conforms to a stability constraint defined for the microgrid system;
and
adjusting the at least parameter to bring the electric power storage device into conformity;
inserting the electric power storage device into the microgrid system;
wherein the microgrid system comprise two or more connected microgrids;
and
wherein at least one of the of electric power storage capacity, charge rate, or discharge rate of the electric power storage device is controlled based at least in part upon specified power source parameters in the two or more connected microgrids and specified load parameters in the two or more connected microgrids.
