N2 - For future power system, a micro power grid system, which is mainly composed of several power modules, such as superconducting (SC) cable, superconducting magnetic energy storage (SMES) system, hydrogen system, fuel cell (FC) system, renewable energy modules, and power converter modules, is expected. In the grid system, hydrogen mainly produced by renewable energy is liquefied for cooling down of the SC cable and SMES, and is stored in a tank for generation of the electric power through the FC. Since the SMES has quick response to power fluctuation and the fuel cell with the hydrogen can supply constant electric power for longer time, the combination of the SMES and the FC can generate highly qualified electric power. The cable can simultaneously transfer both electric power and hydrogen fuel with refrigerant energy. We investigate functions of various power modules and simulate the power balance of the micro grid to estimate the energy recovery rate. It is found that the proposed micro grid can reduce the energy transfer loss.
