摘要：助力“双碳”战略目标，新能源发电在能源系统低碳转型中发挥重要作用，将逐渐成为主力电源。然而，由于新能源发电固有的波动性，新能源消纳困难成为瓶颈问题。电极式电制热作为负荷侧宝贵的灵活性资源，对新能源消纳具有良好的支撑作用。首先，结合电制热的性能和结构特点，分析了现有电制热技术的工作原理。然后，整理了电极式电制热、固态电制热和传统制热在转换能效、爬坡速率以及安全程度等方面的差异。最后，针对电极式电制热无级调节、响应速度快等优势，论述了电极式电制热在电网削峰填谷、供暖期解放火电机组、参与调频辅助服务等方面的应用前景。
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.
