The revolution and wide usage of power electronics devices in modern power system leads to non-sinusoidal voltage and current waveforms due to addition of harmonic signals to the fundamental signals. Defining the total apparent power under non-sinusoidal condition by obtaining different power components for a balanced three phase system is presented in this paper. The apparent power is decomposed in the average and oscillatory power components. The power decomposition proposed in this paper can be used in the power balance equations in load flow analysis under non-sinusoidal conditions as well as in compensator design. To verify the equations derived, a Case study of a distorted system is considered. The power components and total apparent power calculated are compared with the power decomposition given in IEEE Standard 1459-2010 . It is found that the values are satisfactorily matching. Thus accurateness of the proposed method is demonstrated.
