Electrolytic Aluminum Load Participating in Power Grid Frequency Modulation Method Based on Active Adjustable Capacity Coordination

摘要

In recent years, new energy power generation has developed rapidly, and how to absorb the fluctuation of power grid frequency caused by the fluctuation of new energy is the main direction of future development. Using the damping effect of load to simulate the response of load to frequency deviation plays an important role in system frequency response. Usually, the damping coefficient of load is considered as a constant, which can not be adjusted, and is usually measured by practice. This paper studies the effect of electrolytic aluminum with large industrial load on frequency response of power grid. Electrolytic aluminum load is a voltage-driven DC load, which has no frequency response, but has large load capacity and great adjustable potential. Based on this, this paper studies a load damping control method, which responds to the system frequency change by controlling the saturable reactor. The simulation results verify the effectiveness of the proposed control method.
