Abstract: The large-scale integration of renewable energy makes traditional frequency regulation resources unable to meet the frequency regulation demands of the new power system. Electrolytic aluminum, as a typical high-energy load, has great potential for frequency regulation due to its load characteristics of large capacity and flexible adjustment. Aiming at the control characteristics of electrolytic aluminum, an adaptive control strategy with parameters varying with frequency is proposed. The electrolytic aluminum participates in primary frequency regulation by controlling the saturable reactor. This strategy maintains a stable output curve while making the response speed of the electrolytic aluminum faster, and accelerates the frequency recovery. In order to ensure that electrolytic aluminum participating in frequency regulation for many times has less impact on production efficiency and output. In this paper, the quantitative model of the impact of electrolytic aluminum participating in frequency regulation on the production process flow is established, and based on this, an energy recovery strategy for electrolytic aluminum participating in frequency regulation is proposed. On the premise of ensuring that the frequency recovery is not significantly affected, the electrolytic aluminum quickly returns to its initial working state. Finally, the effectiveness and universality of the control strategy and recovery strategy are verified through cases.
