Fuel Cell Output Scheduling With Early Unit Switching

The patent applies preliminary action by advancing the timing of changing the power-generating number of fuel cell units before the scheduled unit period change timing. The control device determines the actual output change timing of the fuel cell device and sets the power-generating number change timing to precede this actual change timing, thereby proactively compensating for the delay between planned and actual output changes. This reduces planning errors by anticipating and preparing for the inevitable lag in actual output response.

The patent implements feedback by continuously monitoring the actual output of the fuel cell device and using this information to dynamically adjust the timing of power-generating number changes. The control device determines the actual output change timing based on real-time output data and adjusts the control strategy accordingly. This feedback mechanism enables accurate power generation planning while maintaining operational simplicity through automated, data-driven decision-making.

The patent applies preliminary action by shifting the power-generating number change timing from the unit period boundary to a point before the actual output change timing. This proactive adjustment maintains the structured approach of scheduled changes while correcting the timing to account for the delay between planned and actual output. The control device calculates the appropriate advance timing based on the determined actual output change timing, thereby preserving plan structure stability while improving power generation accuracy.
