| description | In recent years, the solid-state electro-thermal storage device has been connected to the power supply side of the power system for peak regulation by virtue of its high voltage and large capacity characteristics, which plays a positive role in the consumption of wind power, photovoltaic and other new energy. Based on the coupling effects of heat, current, electricity, magnetism, force and other physical fields in the equipment, this paper studies the optimal design of thermal storage structure. A multi-physical field and multi-criteria collaborative optimization design method was proposed to design the surface load of heating power, heat transfer channel of heat storage body, and porosity of body. Through the multi-field coupling numerical simulation and experiment verification, the thermal field, flow field, stress field, electric field and other changes are analyzed, and it is verified that the design method can effectively overcome the malpractice of low heat transfer rate temperature imbalance of thermal storage materials. The experimental results provide theoretical guidance for device design and engineering application. |
