An increasing number of power electronic based Distributed Generation (DG) systems and loads generate not only characteristic harmonics but also unexpected harmonics. Several methods like impedance based analysis, which are derived from the conventional average model, are introduced to perform research about the harmonic interaction. However, it is found that the Linear Time Invariant (LTI) based model analysis makes it difficult to analyze these phenomena because of the timevarying properties of the power electronic based systems. This paper investigates gridconnected converter by using the Harmonic State Space (HSS) small signal model, which is based on a Linear Timevarying Periodically (LTP) theory. The proposed model can include the switching behavior of the model, where it makes the model possible to analyze how harmonics are transferred into both the acside and dcside circuits. Furthermore, a harmonic matrix of the gridconnected converter is developed to analyze the harmonic interaction at the steadystate behavior. Besides, the frequencydomain results are compared with timedomain simulation results by using HSS modeling to verify the theoretical analysis. Experimental results are finally discussed to verify the proposed model and study.
