• providing (120) an inventory of available bypass components (4), wherein installation and/or usage of each bypass component (4) is associated with a penalty value (4a);
• providing (130), for each customer (3) of the water distribution network (1), a penalty value (3a) that is associated with supply interruption of this customer (3) during isolation of the leak (1a);
• determining (140), based on the inventory of available bypass components (4), bypass connections (4#) between junctions i and j in the water distribution network (1), additive penalty contributions (5+) for installation and/or usage of such bypass connections (4#), and subtractive penalty contributions (5-) for reconnection of customers (3) to a water source (2) by virtue of the bypass connections (4#);
• setting up (150), for each such pair (i,j), at least one equation (6), said at least one equation (6) in at least the flow qij through the bypass connection (4#) and the switching state sij of the bypass connection (4#) stipulating that, of the conditions:
∘ the difference hi - hj between the head hi at junction i and the head hj at junction j shall be dependent on the flow qij through the bypass connection according to a given continuity function Δhij(qij), and
∘ the flow qij shall vanish,
at least one condition is satisfied;

• optimizing (160) for a set of flows qij and switching states sij that fulfils the system of equations (6) while carrying a low overall penalty; and
• determining (190) the obtained set of flows qij∗ and switching states sij∗ as the sought configuration (1*) of the water distribution network (1).

摘要： The invention relates to the field of hydrogen production plant, particularly to a method for producing hydrogen in the hydrogen production plant by using two types of electrolysis systems. The first electrolysis system (ES1) comprises an active DC module (Ma) and at least one first-type electrolyzer (E1), which is configured for producing a first hydrogen output (HO1) by using a first power from the active DC module (Ma), and the second electrolysis system (ES2), comprising a passive DC module (Mp) and at least one second-type electrolyzer (E2), which is configured for producing a second hydrogen output (HO2) by using a second power from the passive DC module (Mp). The method comprises the steps of:
in a ramp-up phase, increasing the first hydrogen output (HO1) of the first electrolysis system (ES1); and
when the first hydrogen output (HO1) of the first electrolysis system (ES1) crosses a first predefined hydrogen output threshold (HO thres1 ),
switching on the second electrolysis system (ES2), and
decreasing the first hydrogen output (HO1) of the first electrolysis system (ES1) to the first predefined hydrogen output threshold (HO thres1 ) minus the second hydrogen output (HO2),
so that an overall hydrogen output (HO total ) of the hydrogen production plant (HPP) is a sum of the first hydrogen output (HO1) and the second hydrogen output (HO2).

摘要： The invention provides a computer-implemented method for controlling operation of an electrolyzer plant. The method comprises determining, by means of a first model, first operating points of the electrolyzer plant for a predetermined first period of time, simulating, by means of a second model, operation of the electrolyzer plant for the first operating points for a predetermined second period of time that is shorter than and comprised in the first period of time, the second model being a model having higher prediction accuracy for the operation of the electrolyzer plant than the first model, and determining whether the simulated operation meets a predetermined requirement. The method comprises, upon determining that the simulated operation does not meet the predetermined requirement, adjusting one or more parameters and/or one or more boundary conditions of the first model, and upon determining that the simulated operation meets the predetermined requirement, setting the first operating points as target operating points for the predetermined second period of time.
