Harmonic load flow for radial distribution systems

Radial distribution systems (rds) require special load flow methods to solve power flow equations owing to their high r/x ratio. increasing use of power electronic devices and effect of magnetic saturation cause harmonics in rds. this paper proposes a novel algorithm to compute the power flow solution of a rds accounting for all the harmonic components. it uses a recursive solution technique. the proposed method uses a novel dynamic data structure reported in the paper. the proposed method is tested upon a 33-bus rds and the results are reported. © school of engineering,taylor's university.
