Abstract
Improving the energy efficiency of the power grid complex is an urgent problem. The need to solve this problem is due to various technical and economic reasons. First of all, this is due to high power losses in distribution electrical networks, caused by a significant load of its elements by reactive power flows. In this regard, the development of mechanisms for active-adaptive control of reactive power is becoming increasingly important. Currently, the Smart Grid concept has become widespread in the global electric power industry. The use of these technologies allows not only to optimize power losses in distribution networks, but also to improve the efficiency of the electric grid complex. The article proposes an algorithm for optimizing the placement of compensating devices in the distribution network on the example of one of the territorial network organizations of the Kuzbass. This algorithm is based on the theory of multilevel systems using the method of indefinite Lagrange multipliers. The results of applying this algorithm based on the developed simulation model are presented.

There are over 3,000 power grid companies operating in the power grid complex of the Russia
As a result of the research, an algorithm was developed to optimize the placement of compensating devices in the distribution network on the example of one of the territorial grid organizations of Kuzbass, based on the theory of multilevel systems using the method of indefinite Lagrange multipliers [1]
The relevance of the innovative development of the Russian power grid complex based on this concept is due to the low potential for increasing the efficiency of the use of power grid assets and the limited investment resources
Summary
There are over 3,000 power grid companies operating in the power grid complex of the Russia. A significant part of these companies is characterized by relatively low energy efficiency indicators This is due to significant power losses in distribution networks, as well as high depreciation of power grid equipment. Analysis of the structure of technological power losses shows that they are largely determined by the excess reactive power transmitted through the network [1]. It follows from the diagram (Fig. 1) that the share of losses due to the transfer of reactive power accounts for 47%. The need to solve this problem is due to various technical and economic reasons
