An integrated scheme to coordinate preventive control and emergency control for transient stability enhancement in power systems

This paper proposes an integrated optimization scheme to coordinate the preventive control and emergency control in order to improve the transient stability in power systems. A linear mixed integer programming model, based on the sensitivity methods of Transient Energy Function, is presented to tackle dynamic security dispatching problems. The approach is tested on a 36-bus power system. The results show that the proposed comprehensive scheme can deal with the problem of transient stability effectively, and it is compatible with operation requirements in practical systems.
