#### Abstract

In carrying out a reactive power compensation it is necessary to select the powers of compensation units for minimizing the active power losses as well as minimize financial losses of installing the reactive power compensation units. Thus, there is a multi-factor optimization problem for sizing of reactive power compensation devices. The paper studied the effect of bare overhead conductors heating to the optimal choice of measures to reduce electricity losses by the example of reactive power compensation. We describe two stages in the selection of reactive power compensation devices and their clarification considering the grid elements temperature. We determine the economic efficiency calculations results of using reactive power compensation as measures to reduce losses in grids, with and without the grid elements temperature dependence consideration. We consider the data on the optimal choice of compensating devices and payback period determination depending on the load, the conductor type and the grid length. The research results can be applied in the optimization of existing systems and in the design of power supply systems of enterprises to reduce the active power losses with the minimal cost of compensation units.
