Due to their unpredictable generation patterns, large-scale wind farms may affect the voltage stability of their integrated power systems negatively. This paper proposes a novel on-line collaborative voltage stability control method to eliminate the negative impact of large-scale wind farms integrated with a power system. The implementation of the proposed method is based on the on-line collaboration of existed local control devices installed in the power system to enhance their total control efficiency. The on-line control collaboration operates on the basis of a proposed protocol of information exchange for multi-agent systems. In the paper, an example of multi-machine power system is presented where a multi- agent system for the on-line collaborative voltage stability control of local devices, including AVRs, STATCOM and circuit breakers is set up. Effectiveness and feasibility of the proposed method to eliminate the threat to system voltage stability posed by the integrated large-scale wind farms is demonstrated.
