Voltage stability continues to be a critical wide-area phenomenon in power systems. WAMPAC infrastructures have improved the voltage stability margin, but for betterachievements the margins, Multi Agent System technology has been merged in some studies. This paper proposes an approachto form a Multi Agent System by reactive and bus agents and discusses about the strategy of arranging them to take this advantage in voltage control plan of a transmission network. Theprinciple of the proposed strategy is to give the allocation of reactive agents according to their effectiveness in supporting thevoltage of the bus. Also, the criterion for the number of agents to be called by a bus agent in an under voltage condition due to a contingency is presented.
