Models for dynamic interaction of wind turbine generators (WTGs) on electric utility networks have been suggested, but only a few publications have addressed the aggregation of hundreds of turbine generators. This topic has a significant impact on studies related to power system dynamics, because it helps reduce system complexity and computation cost. This article features a study that set out to: simulate the electromechanical dynamics of a typical grid-connected wind turbine generator, test an aggregation technique for representing a group of WTGs by a single unit, and demonstrate how such a complicated analysis of interconnected systems can be performed using state-of-the art software that performs both numerical simulation and linearized eigenstructure studies. The SIMULINK software simplifies the analysis of the interconnected power systems, performing both numerical simulation and linearized eigenstructure studies.
