Fuel cell response to electrical grid frequency events
A method for addressing electrical grid frequency changes by a fuel cell system includes measuring, by a frequency sensor, a frequency of an electrical grid, determining that the frequency of the electrical grid differs from a normal frequency of the electrical grid by a threshold, determining, base...

| description | A method for addressing electrical grid frequency changes by a fuel cell system includes measuring, by a frequency sensor, a frequency of an electrical grid, determining that the frequency of the electrical grid differs from a normal frequency of the electrical grid by a threshold, determining, based at least in part on the measured frequency, an AC power setpoint bias, applying a magnitude limit, a rate-of-change limit, and a duration limit to the determined AC power setpoint bias to generate a limited power setpoint bias, generating a frequency adjusted power setpoint based on the limited power setpoint bias, and providing the frequency adjusted power setpoint to one or more control modules of the fuel cell system such that the fuel cell system adjusts a power output based on a difference between the measured frequency and the normal frequency. |
