1. A method, comprising: receiving at least one parameter for a source of electric power into a computer-readable model of a proposed microgrid; receiving at least one parameter for a variable load that consumes electric power into the computer-readable model of the proposed microgrid; responsive to receiving the at least one parameter for the source of electric power and the at least one parameter for the variable load, the computer-readable model computing at least one parameter for at least one electric power storage device having a customized profile that is to be placed in the proposed microgrid, the electric power storage device configured to retain electric power generated by the source of electric power and discharge electric power requested by the variable load, the at least one parameter for the at least one electric power storage device computed based at least in part upon the at least one parameter for the source of electric power and the at least one parameter for the variable load, and wherein the at least one parameter for the at least one electric power storage device conforms to a stability constraint for the microgrid; wherein the at least one parameter of the at least one electric power storage device is one of electric power storage capacity, charge rate, or discharge rate; and wherein the customized profile conforms to one or more stability constraints; and dynamically controlling and installing an electric power storage device with the customized profile comprising the at least one parameter of the electric power storage device into an operating microgrid; wherein the customized profile is indicative of the at least one parameter of the electric power storage device that is to be included in the microgrid that satisfies the stability constraint.
