Load Model with Small Generators Considered

In this paper, based on coherency equivalence algorithm, a new equivalent load model of distribution network which contains small generators is presented. Because in distribution network, the electric distance of any two small generators is short, all small generators can be divided into only one coherent group, which has been verified by substantial electric simulations. Aggregation of electromagnetic circuit of, prime mover governor of, excitation of, power system stabilizer of small generators into only ones have been inferred explicitly too. In addition, effectiveness of this method has been verified by a simulation.
