Determination of impact in intelligent voltagecontrol system in distribution electric networks

The urgency of the work is connected with the improvement of the components of the distributed automation system and voltage control within the framework of the development of actively adaptive electrical networks. An approach is presented to the determination of control actions within the framework of coordinated voltage control in distribution electrical networks using active elements based on multi-agent control. Voltage control in the electric network is carried out by all local regulators within the boundaries of the controlled zone under the condition of voltage stabilization. The control actions of local agents are determined as a result of coordination between each other in the type of "auction", the solution of the linearized optimization problem based on the sensitivity of the locations of the active elements to the change in voltages in the distribution network. The sensitivity of the parameters of the regime to the injection of power in the nodes of the electrical network is determined on the basis of sensory analysis of the conductivity of the network topology elements and the partial derivative of the unbalance of the constituent electrical quantities. Achieving the global goal of managing coordinating agents is achieved by optimizing the mode parameters and adjusting the work of local agents. The presented simulation results on the test circuit showed the feasibility and effectiveness of the proposed approaches..
