1. A method of providing a frequency response to an electrical grid with a distributed energy resource (DER), the method comprising:
transitioning to an active state and drawing energy from or discharging energy to the electrical grid;
maintaining a timer that indicates an amount of time since the DER transitioned to the active state or a remaining amount of time before the DER will cease drawing or discharging energy and transition from the active state to an inactive state;
calculating a timer interruption threshold according to a measured frequency of the electrical grid;
comparing the timer to the timer interruption threshold; and
interrupting the active state in response to the timer exceeding the timer interruption threshold.
