1. A computer-implemented method, the method comprising:
identifying an amount of power for a set of energy storage units, each energy storage unit including an energy storage device and a power conversion device that interfaces with an electric power grid;
determining an allocation of power for a first plurality of energy storage units associated with a first controller and a second plurality of energy storage units associated with a second controller, the first plurality of energy storage units located at different geographical locations from the second plurality of energy storage units, the allocation of power determined based on:
a first tier defining a f irst state-of-charge metric and a first load operations schedule associated with the first plurality of energy storage units; and
a second tier defining a second state-of-charge metric and a second load operations schedule associated with the second plurality of energy storage units; and
providing, based on the first tier and the second tier, the allocation of power for the first plurality of energy storage units to the first controller that controls the first plurality of energy storage units and the allocation of power for the second plurality of energy storage units to the second controller that controls the second plurality of energy storage units, wherein providing the allocation of power f or the first plurality of eneray storage units aid the allocation of power for the second plurality of eneray storage units causes at least a portion of the set of eneray storage units to charge and/or discharge based on the first load operations schedule implemented by the first controller and/or the second load operations schedule implemented by the second controller.
