Frequency response optimization based on a change in battery state-of-charge during a frequency response period

A method for optimizing frequency response during a frequency response period, the method comprising:

• generating an optimal frequency response midpoint for participating in a frequency response program;
• constraining the optimal frequency response midpoint based on a change in a state-of-charge (SOC) of a battery during the frequency response period;
• determining optimal battery power setpoints for a power inverter based on the optimal frequency response midpoint;
• and
• controlling an amount of the electric power stored to or discharged from the battery by the power inverter based on the optimal battery power setpoints.

A frequency response controller including a computer readable medium and a processor, the frequency response controller comprising computer executable instructions stored in the computer readable medium to:

• generate an optimal frequency response midpoint for participating in a frequency response program;
• constrain the optimal frequency response midpoint based on a change in a state-of-charge (SOC) of a battery during a frequency response period;
• determine optimal battery power setpoints for a power inverter based on the optimal frequency response midpoint;
• and
• control an amount of the electric power stored to or discharged from the battery by the power inverter based on the optimal battery power setpoints.
