The views that the energy oscillations between supply sources and loads are responsible for the degradation of the effectiveness of the energy transfer are very common in the power engineering community. A suggestion by the Instantaneous Reactive Power p-q Theory that such oscillations should be removed by a compensator, can result in an erroneous control of switching compensators. The paper shows that energy oscillations do not affect the energy transfer effectiveness, however. The roots of this major misinterpretation are discussed as well. The physical meaning of the reactive power is also investigated in the paper, with the conclusion that there is no physical phenomenon that could be described in terms of the reactive power.
