As distribution static var compensator (DSVC) can synthetically manage power quality problems, the interactions among the DSVC controllers should be considered. The paper establishes the linearized model of a single-load infinite-bus distribution system installed with two DSVC considering the induction motor load, and the system transfer function array can be obtained based on this model. Then, the singular value decomposition (SVD) method is used to analyze the interactions under different electrical parameters, drawing a conclusion that the interactions will be strengthened when the electrical distances are decreased. The simulation results verify the effectiveness of the proposed model and the SVD method.
