摘要
The AGC(Automatic Generation Control) is researched for the interconnected power grid with hydro and thermal power plants. The AGC state space mathematical model of a two-area power grid is established. A dynamic performance index is introduced and a strategy of optimal dynamic closed-loop AGC based on optimal control theory is proposed. Compared with the full state feedback control, it reduces the internal coupling of the interconnected system and masters timely the critical states within system, resulting in better practicability and maneuverability. Compared with the traditional PI control, it carries out a comprehensively dynamic control, resulting in better dynamic adaptability to complex interconnected power grid. Simulation verifies the correctness of theoretical analysis.
