摘要：An improved nonlinear (IN) H control of unified power flow controller (UPFC) is investigated and designed in the power system by using the Hamiltonian function method. First, the dissipative Hamiltonian structure of the UPFC system is established by means of variable transformation. Then, based on the obtained dissipative Hamiltonian structure, an IN H control is put forward. Simulation results on the two-area four-machine power system demonstrate the effectiveness and robustness of the IN H control in comparison with that of feedback linearization control (FLC) and add-on self-tuning (ST) control. The research results show that the IN H control has better performance than the two other controls.
