“…The following issues are mainly a matter of concern in some publications on this theory. (i) Some papers [7, 8] report a low performance of the compensators with the IRP p − q theory‐based control in the presence of the supply asymmetry and/or harmonic distortion. (ii) Possibility of an increase of the supply current distortion when a compensator is controlled with the IRP p − q theory‐based algorithms, in [3, 9–12, 24, 25]. (iii) There are different opinions [3, 13–15] whether the IRP p − q theory makes instantaneous compensation possible or not. (iv) There is still confusion, reported in [15, 16, 17, 23], as to the physical interpretation of the IRP q . The first three issues, that is, (i)–(iii), have a practical importance, while the last, (iv), only a cognitive one.…”

“…Items (i) and (ii) imply a question: ‘do p and q powers really convey information sufficient for a compensator control without any restrictions as to the three‐phase system properties?’ The conclusions of the papers [7–12, 24, 25] show that the answer to this question seems to be negative. It means that some restrictions on using the p and the q powers in the control algorithms are necessary.…”

The instantaneous reactive power (IRP) p-q theory can be acknowledged as the first concept that provided fundamentals for switching compensator control and very often such a control is satisfactory. There are situations when this control can result in objectionable effects, however. Instantaneous active and reactive powers, p and q, defined in the IRP p−q theory, were introduced with the emphasis that the definitions of these powers are valid for any three-phase system, without any constraints as to the system properties with respect to the load structure and the supply voltages and load currents waveform. This may imply a conclusion that the instantaneous powers p and q specify the power properties of the threephase systems regardless of such systems properties. This assurance regarding the lack of constraints has contributed to the dissemination of the IRP p−q theory, especially as a fundamental of the algorithms for switching compensator control. This study shows that such a conclusion has no ground, however. In fact, only at very specific properties of the three-phase system some conclusions on its power properties can be derived from the values of the instantaneous active and reactive powers. Also, it shows that the IRP p−q theory identifies the power properties of the three-phase loads correctly only on the condition that such loads are supplied with symmetrical and sinusoidal voltage.

The amount of distributed generation (DG) such as photovoltaic systems and wind power generator systems installed in distribution systems has been increasing because of reduction of the effects on the environment. However, harmonic problems in the distribution system are a concern in the context of increased connection of DGs through inverters and the spread of power electronics equipment. This paper proposes a method for the restraint of voltage total harmonic distortion (THD) in a whole distribution network by active filter (AF) operation of multiple power conditioner systems (PCSs). It also proposes a method for determination of the optimal gain of AF operation so as to minimize the maximum value of voltage THD in the distribution network by real‐time feedback control with measured data from information technology (IT) switches. In order to verify the validity of the proposed method, numerical calculations are carried out using an analytical model of a distribution network of interconnected DGs with PCSs. © 2012 Wiley Periodicals, Inc.
