Load Modeling Considering Distributed Generation

Distributed generation is regarded as the developing direction of the power system in 21 century. Because distributed generation always connects with the distribution system, which has great influence on every aspects of power system. This paper studied the influence of distributed generation on load modeling. When the influence of distributed generation is not negligible, the composite induction motor load model can´t effectively describe the actual load characteristic. This paper proposes a new load model-asynchronous generator +ZIP. The validity of the proposed load model is also testified via the comparison and contrast from a great deal of simulations. Then, composite induction-motor and asynchronous generator +ZIP load models were unified in one program.
