In view of the nonlinear time-delay multi-machine power system, involving the local and remote signals into the controller design and considering the diversity of the signal delays, a port controllable Hamilton model is constructed. The model takes steam valve as control variable and takes into account the influence of the disturbance. Based on the proposed model, aiming at a certain form of H function, the corresponding Lyapunov function with some specific H function as its part energy function is given to derive a delay-dependent stability criterion. By energy-shaping method, the PCH model of a general power system could be transformed into a PCH model with specific H function and the corresponding full-state feedback controller is designed according to the stable criterion. Finally, taking a 3-machine 9-bus power system as an example, the simulation results show that the performance of controller is effective in the nonlinear time-delay system with disturbance.
