摘要：The article concerns a mathematical description of electric power in the case of two nonlinear receivers connected to a common supply network. This description was made on the basis of the fundamental CPC (Currents' Physical Components) power theory. This theory was developed for one nonlinear receiver. In the case of two nonlinear receivers of the same type, i.e. when the harmonics generated by them are created equal, the CPC theory requires some modification. This issue is important when it is necessary to determine the components of currents in an energy system supplying two nonlinear receivers.
