Abstract: To help achieve carbon peaking and carbon neutrality, the new energy power generation plays an important role in the low-carbon transition of energy system and will gradually become the main power source. However, due to the inherent volatility of new energy power generation, the difficulty of new energy consumption has become a bottleneck problem. As a valuable flexible resource on the load side, the electrode electric heating has a good support for new energy consumption. Firstly, combined with the performance and structural characteristics of electric heating, the working principles of the existing electric heating technologies were studied. Then, the differences of conversion efficiency, ramp rate, and safety between the electrode electric heating and solid-state electric heating and traditional heating methods were analyzed. Finally, in view of the advantages of stepless regulation and fast response speed of electrode electric heating, the application prospects of electrode electric heating in peak-cutting and valley-filling of power grid, liberation of thermal power units in heating period, and participation in auxiliary service of frequency regulation were discussed.
