Harmonic analysis in power systems is a significant challenge due to the increasing prominence of harmonics and owing to customer requirements for high power quality. This paper proposes a new harmonic power flow method and considers different key categories of nonlinear loads: loads with defined nonlinear V-I functions, thyristor-controlled converters, and inverters. A novel formulation for each device is derived and the effect of these harmonic sources are studied in single-source and multiple source scenarios. This method is not only simpler than conventional methods but also reveals the same precision. The method is implemented on the IEEE 14-bus system and different scenarios are studied. The results are compared to other methods in literature which proves the precision, applicability, and efficiency of the proposed method.
