    摘要： A method (100) of optimizing at least a part of a hydrogen, H 2 , production plant (300), and a system comprising the at least a part of the hydrogen production plant, are provided. The method comprises obtaining a first set of data (110) associated with component categories (120a-c) comprising component category type(s) (130a-c). The first set of data comprises a first and a second subset (150, 160) associated with a capital expenditure, and am operational expenditure, respectively, of each component category type. The method further comprises obtaining a second set of data (180) and a third set of data (190) associated with a cost of electrical power and ancillary service(s), respectively, and determining (200) the at least a part of the hydrogen production plant by a combination of the component category type(s) based on optimization criterion(s) (250) as a function of the first, second and third set of data.

    摘要： 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.

    摘要： A charging and field supplement circuit for superconducting magnets based on a pulsed current includes a capacitor charging circuit, an energy-storage capacitor, a capacitor discharging circuit, a superconducting magnetic energy storage circuit, and a superconducting persistent-current switch. Two output ends of the capacitor charging circuit are respectively connected to two ends of the energy-storage capacitor. Two input ends of the capacitor discharging circuit are respectively connected to the two ends of the energy-storage capacitor. Two output ends of the capacitor discharging circuit are respectively connected to two input ends of the superconducting magnetic energy storage circuit. Two output ends of the superconducting magnetic energy storage circuit are respectively connected to two input ends of the superconducting persistent-current switch. Two output ends of the superconducting persistent-current switch are configured to charge and magnetize a target superconducting magnet.
