-This paper presents an adaptive optimal control strategy for enhancement of the integrated AC/DC power system performance. The system modeling is general and applicable to large scale power systems with an embedded HVDC link. The control algorithm incorporates the nonlinear power system dynamic equations. A novel feature of this development is the use of real-time system measurements as inputs to the optimal controller. The closed loop optimal control law consists of both model and measurement based terms. The effectiveness of the optimal control algorithm in damping the electromechanical oscillations is illustrated with the use of a nine-bus AC/DC system.
