In this paper, a method of model predictive control for load frequency control is proposed. The proposed method considers the terminal state into the cost function, which can accelerate convergence speed. And it also can address the realistic constraints. Firstly, a continuous state space model for LFC system is constructed. Because the MPC controller worked on discrete time, the continuous state space model is transformed into discrete state space model. Secondly, due to the quadratic programming is used in this paper to solve the optimal control sequence, the formula derivation procedure is presented in detail. Then, considering the constraints in real LFC system, the constraints matrix is also given. In the end, the simulation in Simulink verifies the effectiveness of the proposed method.

摘要

In this paper, a method of model predictive control for load frequency control is proposed. The proposed method considers the terminal state into the cost function, which can accelerate convergence speed. And it also can address the realistic constraints. Firstly, a continuous state space model for LFC system is constructed. Because the MPC controller worked on discrete time, the continuous state space model is transformed into discrete state space model. Secondly, due to the quadratic programming is used in this paper to solve the optimal control sequence, the formula derivation procedure is presented in detail. Then, considering the constraints in real LFC system, the constraints matrix is also given. In the end, the simulation in Simulink verifies the effectiveness of the proposed method.
