This paper proposes a Fast Harmonic Analysis (FHA) method for efficient harmonic analysis in distribution power networks with converter-interfaced distributed energy resources (CIDERs). The integration of CIDERs, such as photovoltaic and wind power, introduces harmonic distortion due to power electronic converters. Harmonics can impact power transmission efficiency, damage equipment, and cause measurement errors. The FHA method utilizes time-domain Kron reduction and considers harmonic interactions between different frequencies to accelerate simulation speed and improve accuracy. A comparison with the harmonic power flow (HPF) method is conducted, and the harmonic characteristics of distribution power networks with CIDER integration are analyzed using FHA. The proposed FHA method offers a valuable contribution to effective harmonic analysis and management in distribution power networks with CIDERs.
