Abstract

This paper proposes a multi-objective operational optimization model for an electro-hydrogen-methanol coupling system featuring PEM-AWE mixed electrolytic cells and energy bidirectional conversion functionality. By combining the high responsiveness of PEM with the low-cost advantage of AWE, and through the coordination of the electrical energy subsystem, hydrogen energy subsystem, and methanol energy subsystem—as well as the bidirectional energy conversion among these subsystems—the system’s regulatory capacity and economic efficiency are effectively enhanced. Furthermore, the validity of the model is verified through case studies, providing operational strategies that balance economic efficiency, renewable energy integration, and system stability for the development of new power systems dominated by a high proportion of renewable energy.
