Chaos based multi-agent coordination with sharing resources for secondary voltage control in power-system voltage stability

The secondary voltage control (SVC) of power systems initiated by EDF has been developed successfully to improve power-system voltage stability. And, with the development of agent technique, multi-agent system (MAS) has been applied in SVC to maintain the system voltage more stable. The models established in previous papers on MAS based secondary voltage control with no sharing resources and information delays. So a study of the chaotic dynamics of the MAS is presented in this paper, which shows us what helps to eliminate the unstable dynamics of the MAS in resources sharing. And a more efficient MAS model, with resources sharing, in the emergency mode is established to meet the needs of the secondary voltage control for power system in this paper. The simulation results of the New England 39-bus system show that the proposed MAS are efficient in managing global voltage control of power system comparing with the normal MAS scheme.
