The DC microgrids based on renewable energy sources (RES) are simple to be implemented in residential houses and should be possible solution for the energy crisis. This paper presents the preliminary results of the implementation of the power-following strategy in a DC microgrid using a fuel cell / electrolyser unit. The fuel regulators of the fuel cell (FC) system will be controlled by the FC current and the boost DC-DC converter interfacing the FC stack with the DC bus will be controlled using the power-following strategy when the regenerable power are less that the load demand. During the period when the renewable power exceeds the load demand, the excess power will supply the electrolyser unit to operate the battery in charge-sustained mode (with the advantage of a smaller size of the battery pack). The advantages of DC microgrid operation using an energy management strategy based on power following for the hydrogen-based energy generation and storage system are presented.
