摘要：
In order to estimate the harmonic pollution caused by the residential loads, a dynamic adaptive harmonic coupled admittance matrix (HCAM) model was proposed for the nonlinear household appliance. Firstly, the partial least squares (PLS) method was used to solve the parameters of HCAM model of nonlinear home load based on the measured voltage and current data. This method can effectively overcome the multicollinearity problem among the input data. The model can reflect the coupling relationship between harmonic voltage and harmonic current. Then, based on the recursive PLS method, an adaptive updating method of model parameters was proposed, so that the model can be adjusted adaptively with the fluctuation of load supply voltage, and the harmonic characteristics of load fluctuating with supply voltage can be accurately illustrated. The effectiveness and accuracy of the proposed model are verified based on the analysis results of the typical home nonlinear loads. It is used to evaluate harmonic emission level accurately in low voltage distribution system. © 2020 Chin. Soc. for Elec. Eng.
