Multiple-node models of asynchronous wind turbines in wind farm for load flow analysis

Abstract

Considering load flow analysis of power system integrated with multiple wind generators (WGs), the Multiple-Node Models of an asynchronous generator are proposed in this paper. It is more convenient to use the Multiple-Node Models for load flow problem, because the models can be directly applied to conventional load flow programs, and the iteration process of the rotor slip is no longer needed. In addition, a kind of aggregation methodology is presented to aggregate a wind farm into multiple WGs in this paper. The case study is carried out on the basis of the modified IEEE-30 test system, and the detailed comparisons are given. The results show the effective performance of the proposed methods.
