The topology of the clean energy system is a flexible structure with PV, wind power, hydrogen storage, and battery storage. Thus, the construction and operation of the clean energy system should pay more attention to the temporal and spatial variations. This paper discussed a solar-storage-hydrogen-charging demonstration to accommodate the diverse temporal and spatial features of the clean energy system. The present study developed a Modelica library to support the cooperative control of this clean energy system based on value stream analysis. The result shows that the sold electricity profit of the electric storage system can reach 2.3 times than the electricity purchase cost. Though the hydrogen charging demand in the demonstration is small compared with the electric load demand, the hydrogen charging profit can be 1.7 times of the energy cost.
