Doubly-Fed Wind Farm Engineering Aggregation Model Used for Planning

Abstract

Establishing an appropriate aggregation model of wind farm is the first step of the electrical computation in wind power integration planning. This paper first summarizes the technical requirements of wind farm model from the viewpoint of engineering, then proposes an aggregation DFIG model of wind farm. Because of the lack of measured data in the planning stage, the single equivalent model is used in this paper, and be improved by considering the equivalent collection lines model. The accuracy of the aggregation model in different electrical calculation, such as power flow, transient stability and shortcut current simulation, is verified through a sample system in DIgSILENT.
