Quality control of electric power is usually performed at the point of delimitation, and mutual influence of the elements of power systems and exchange processes between generators is not considered. But in the transition processes, transmission, accumulation or generation of exchange energy take place both between the supporting elements of the power system and between the generators. The influence of exchange processes on the load is compensated by special instruments and the quality of electricity from a consumer’s perspective is almost not affected. However, mutual overflows of energy, even with full compensation, will produce electromagnetic effect on the equipment (for example, magnetic circuit oversaturation) that would cause deterioration in the operating modes of generators, increasing losses, etc. All the above­said predetermines the need for analysis of exchange processes directly in the intersection of generation. So the calculations were carried out of the exchange capacity during the work of two generators with different modes of operation and the influence of perturbations during the work of one generator was studied. We constructed corresponding graphic dependencies of the exchange capacity on the phase shift angle using MathCAD and Excel software applications. By analyzing graphic dependencies, the conclusions were drawn. Even with an active load, the overflows of inactive power in the system are present. We also defined by the graphs the optimal value of the phase shift angle, at which exchange capacity equals zero. The conducted studies make it possible to carry out analysis and optimization of energy processes in dispersed electric power systems with different energy sources, to identify and minimize unwanted energy flows between the elements of the system, as well as to compensate for the mutual influence of various­type electric power sources, both traditional and non­traditional.
