Abstract
In this paper, conventional AC power theory is fundamentally investigated and a new concept is presented. It is shown that reactive power, defined as the peak value of one of the oscillatory components of the instantaneous power, cannot be obtained in the frequency domain. The discrepancy between frequency and time domain results is presented. It is also shown that in the new concept, reactive power is determined in both time and frequency domains as an imaginary DC value, and the method is consistent for all system topologies. Apparent power is independent of the reference point voltage
