“…This Energy Management System proposes that the energy consumed is adapted to the available energy by switching on/off electrolysis units and regulating the performance of the devices that are connected, following a smart grid approach for the local micro grid [2]. In comparison with previous works [2,18,27], this proposal focuses on using an advanced control system to optimize H 2 production and reduce the connections/disconnections of the appliances [26]. In this work, the produced energy is totally consumed, but the results can be extrapolated to the majority of situations using only the excess energy from green sources [13,29e31].…”

Predictive control Wave energyWind energy a b s t r a c t An Energy Management System (EMS), based on Model Predictive Control (MPC) ideas, isproposed here to balance the consumption of power by a set of electrolysis units in an offshore platform. In order to produce renewable hydrogen, the power is locally generated by wind turbines and wave energy converters and fully used by the electrolyzers. The energy generated at the platform by wind and wave is balanced by regulating the operating point of each electrolysis unit and its connections or disconnections, using an MPC based on a Mixed-Integer-Quadratic-Programming algorithm. This Predictive Control algorithm makes it possible to take into account predictions of available power and power consumption, to improve the balance and reduce the number of connections and disconnections of the devices. Two case studies are carried out on different installations composed of wave and wind energies feeding a set of alkaline electrolyzers. Validation using measured data at the target location of the platforms shows the adequate operation of the proposed EMS.
