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 developed successfully and applied mainly for the generator AVRS to improve power-system voltage stability. Work on secondary voltage control is presented involving various types of power-system voltage controllers, AVRs, SVCs and STATCOMs, for a new application: power-system voltage management in system contingencies. The secondary voltage control is proposed, to be implemented based on the principles of multi-agent system theory, an active branch of applications in the distributed artificial intelligence. An example power system is presented to demonstrate the necessity of the secondary voltage 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-ordination for their secondary voltage control in system contingencies.
