Multi-agent co-ordination for the secondary voltage control in power-system contingencies

The secondary voltage control of power systems initiated by EDF has been de veloped successfully and applied mainly for the generator AVRS to improve p ower-system voltage stability. Work on secondary voltage control is present ed involving various types of power-system voltage controllers, AVRs, SVCs and STATCOMs, for a new application: power-system voltage management in sys tem contingencies. The secondary voltage control is proposed, to be impleme nted based on the principles of multi-agent system theory, an active branch of applications in the distributed artificial intelligence. An example pow er system is presented to demonstrate the necessity of the secondary voltag e control among an AVR, an SVC and a STATCOM installed in the power system, and also to illustrate the success of applying the multi-agent co-ordinati on for their secondary voltage control in system contingencies.
