Abstract As the negative interaction may exist between several different control loops of D-FACTS system, taking DSTATCOM as an example, the paper establishes the mathematic model of DSTATCOM with ac and dc control, analyzes static-state interaction between two control loops with the RGA approach, then the effect of the load and power factor which could be relevant to the interaction above has also been discussed, finally the paper presents variable power-factor reference method to prevent the interaction. The simulation results validate the effectiveness of RGA approach and feasibility of variable power-factor reference method.

Key words： RGA approach DSTATCOM interaction mathematic model variable power-factor
