Coordinated Management Strategy for Off-Grid Electric Hydrogen Integrated Supply Station

This paper proposes a novel energy management strategy for an off-grid electric hydrogen integrated supply station (EHISS). The fuel cell electric vehicle (FCEV) could be supplied both by hydrogen and electric energy, and by utilizing such an energy substitute characteristic, a novel energy trading framework for EHISS is developed. Under this framework, a two-stage price energy coordinated management strategy (PECMS) is proposed. The PECMS combines the source side energy management and demand side energy management, and could influence the users' tendency by regulating the selling price of hydrogen, which further improves the performance of energy management. The PECMS contains a genetic algorithm-mixed integer linear programming (GA-MILP) solving frame in the scheduling stage and a finite state machine algorithm based on the day-ahead scheduling results in the real-time control stage. The optimization of the proposed strategy is then validated in both the scheduling stage using the Gurobi solver and the realtime control stage by simulation.
