| 英文摘要 |
| To the problem that complex power systems are difficult to model accurately, system parameter perturba
tions and nonlinear physical constraints lead to the degradation of frequency modulation performance, a data-driven load
frequency control (LFC) algorithm based on controller dynamic linearization is proposed. Firstly, the nonlinear inter
connected power system is equivalent to a dynamic linear function model and the estimated value of the pseudo partial
derivative (PPD) is obtained by using an adaptive observer. Assuming the existence of an ideal controller, the equivalent
parameterized realizable controller form is given. Secondly, a long short-term memory (LSTM) neural network is construct
ed to adjust the controller parameters online. The stability of closed-loop power system and the convergence of observer
estimation method are proved strictly in theory. Finally, the effectiveness of the proposed load frequency control algorithm
in realizing frequency regulation is verified by simulation on the interconnected power system, which is independent of the
model information of the power system and does not measure the system status signal. |
