Abstract: To accurately prepare an operation plan that achieves efficient operation in a hydrogen system. In a hydrogen system operation planning device of an embodiment, an acquisition unit is configured to acquire performance data regarding performance of a plurality of hydrogen production devices and tentative operation plan data regarding a tentative operation plan tentatively prepared for the operation plan. A prediction unit is configured to acquire performance prediction data by predicting the performance of the plurality of hydrogen production devices during the planning target period based on the performance data and tentative operation plan data acquired by the acquisition unit. A planning unit is configured to acquire the operation plan by correcting the tentative operation plan based on the performance prediction data acquired by the prediction of the prediction unit.

Abstract: To provide a hydrogen system operation planning device capable of accurately preparing an operation plan that achieves efficient operation in a hydrogen system. In the hydrogen system operation planning device of the embodiment, a classification unit receives input of DR commands regarding demand for electric power in the hydrogen system and classifies the input DR commands into a first DR group and a second DR group with a lower priority than the first DR group. A first planning unit prepares a first operation plan to reflect the DR command classified into the first DR group. A second planning unit prepares a second operation plan by reflecting contents of the DR command classified into the second DR group on the first operation plan so that contents of the DR command classified into the first DR group have priority over the contents of the DR command classified into the second DR group.
