1. A frequency response optimization system comprising:
- a battery configured to store and discharge electric power;
a power inverter configured to use battery power setpoints to control an amount of the electric power stored or discharged from the battery; and
a frequency response controller configured to;
receive a regulation signal from an incentive provider in a frequency response (FR) program, wherein the regulation signal indicates a proportion of a regulation award power amount to add to or remove from an electric grid relative to a frequency response midpoint,predict future values of the regulation signal for each time within an optimization time period,use the predicted values of the regulation signal to generate the battery power setpoints for the power inverter for each time within the optimization time period; and
operate the power inverter using the generated battery power setpoints to cause the battery to store or discharge the electric power.

Abstract
A frequency response optimization includes a battery that stores and discharges electric power, a power inverter that uses battery power setpoints to control an amount of the electric power stored or discharged from the battery, and a frequency response controller. The frequency response controller receives a regulation signal from an incentive provider, predicts future values of the regulation signal, and uses the predicted values of the regulation signal to generate the battery power setpoints for the power inverter.
