    Abstract

    An adaptive coordination scheme is proposed to improve the transient stability, voltage security and frequency damping of a power system network by optimally scheduling the parameters of the available controllers. A set of real-time stability indicators, including a transient stability index, transient voltage stability index and damping factor are used to reflect the stabilities of power systems. Then, the relative significances of a group of controllers to the power system are used as references for the optimiser to schedule new controller parameters. This coordinated control scheme effectively allocates power system resources to handle different stability issues in different time frames. The results suggest that power system security can be further enhanced by means of coordinated control.
