Nonlinear coordinated control is presented for synchronous generator excitation and Static Synchronous Compensator (STATCOM). Considering the coordinated control problem of synchronous generator excitation and STATCOM, multi-objective equations are built to include system variables interested by practical operation. When Nonlinear Control method with Objective Holographic Feedbacks (NCOHF) is applied to deal with above coordinated control, a nonlinear control method, called Nonlinear Coordinated Control with Objective Holographic Feedbacks (NCCOHF), is proposed. In this condition, satisfactory dynamic and static-state performances of terminal voltage, active power and angular speed are achieved except for the voltage at the STATCOM connection point. This is because these variables are punished during the course of nonlinear feedback. Finally, simulation model is built to examine the effectiveness of the proposed method.
