This paper proposes the three-level multiagent system for monitoring and control of the networks of 0.4–35 kV modes. Regardless of the level each agent physically represents the electronic-computing machine. It runs at substations of 10 kV as the third-level agents, 35 kV as the second-level agents, 110 kV as the first-level agents or at the micro and the small power plants of the corresponding level. The algorithms, which consider the particularities of corresponding voltage network modeling, implement at each level.
