It is proposed to include the principle of distributed generation of reactive power in the basic principles of constructing smart microgrids for non-commercial facilities. Individual reactive power compensation devices should be installed for its implementation at the points of final distribution of electricity networks of buildings and structures. As a result, in addition to the effect of reducing the losses of electricity in distribution networks from the flow of reactive component currents, it is possible to create virtual sources of reactive power as an auxiliary resource at the disposal of the distribution system operator for solving the problem of providing a balance of reactive power in normal and post-accidental transient operational modes for reliable and high-quality power supply. The article substantiates the expediency and expected effect of reactive power compensation in the electric grids of civil engineering facilities.
