Integrated Control Strategy for Electrolytic Aluminum Load Participation in Frequency Modulation

The introduction of electrolytic aluminum load in a large-scale power system with complex station structure is essential for frequency control (LFC). In this paper, we propose strategy to participate the modulation grid based on IEEE standard two-region LFC model. Besides, fractional-order PID (FOPID) controller designed and compared traditional PID, parameters FOPID are optimized by PSO algorithm. addition, model was built verify integrated participation modulation, which show that algorithm has stronger robustness LFC.
