Abstract
It is important to consider a stabilization problem for a large scale power system. In this paper, we use a dynamic compensator based on observer theory such that desired poles are placed for a closed loop multimachine power system. Since dimension of the system is large, it is difficult to apply a conventional dynamic compensator method to an excitation control problem for a multi-machine power system.
We introduce the homotopy method to solve fundamental nonlinear equations which are required for observer synthesis. To show the effectiveness of the proposed method, we consider an excitation control of generators for a multi-machine power system.
From the simulation result, it is shown that the present method is useful to stabilize a mufti-machine power system.
