Abstract: Nowadays, the problems of power saving and improving the power efficiency of the electric grid complex are among the most urgent. In this respect, distribution grids of territorial network organizations occupy a special place. They are characterized by large transmitted reactive power. This causes significant power losses. Therefore, an important role is played by rational reactive power compensation in these networks. The purpose of this work is to develop a multilevel optimization model for placement of compensating devices in the distribution grids of territorial network organizations, which provides an increase in efficiency of measures of reactive power compensation. The conducted researches were based on general provisions of multilevel systems theory, methods of system analysis, methods of planning and decision-making, and method of uncertain Lagrange multipliers. As a result of the research, a multilevel optimization model fort placement of compensating devices in the distribution grids of territorial network organizations was developed. General principles of the description of the activities of the main levels (level of abstraction, decision-making level and organizational level) and their internal hierarchy are considered. It is established that there are numerous longitudinal and transverse communications on transfer of information between the elements of the three main levels.

Key words: distribution grid territorial network organization reactive power compensation compensating device multilevel optimization model power efficiency
