The efficiency of a microgrid hydrogen circuit

The paper discusses the efficiency of a microgrid hydrogen circuit. We measured and calculated the energy efficiency values to describe two main sources of low efficiency. The principle of the proposed design consists in improving the stability of a direct current microgrid and enabling the maximum exploitation of the electric energy produced by renewable sources. The circuit is composed of a microhydropower plant, solar panels, and wind power plants. In this respect, we present a module to save the energy, proposing an efficiency calculation procedure for the hydrogen circuit.
