Abstract: At present, the problems of rational reactive power compensation are among the most pressing problems of the distribution grid complex. Distribution grids of 6-35 kV of territorial network organizations are characterized by a special structure and properties. Therefore, it is important to solve the problem of optimization of compensating devices placement for these networks. It is obvious that this problem belongs to the class of multicriterial optimization problems. The purpose of this work is to form an objective function and a constraint system when optimizing the compensating devices placement in the distribution grids of territorial network organizations. This provides optimal solutions that are most appropriate to the real operating conditions of power grids. The conducted researches were based on general provisions of the theory of electrical circuits, optimization methods and methods of planning and decision-making. As a result of the research, the main problems of solving the issue of optimization of compensating devices placement in power grids as a multicriterial task are considered. A block diagram of the process for solving the multicriterial optimization problem is presented. Features of setting the task of optimization of placement of compensating devices in distribution grids of the territorial network organizations are considered. The objective function and the constraint system of the problem and also matrix-vectors of optimization results are offered.

Key words: distribution grid territorial network organization reactive power compensation compensating device multicriterial optimization objective function limitation system
