General model for representing variable speed wind turbines in power system dynamics simulations

TLDR

Wind turbines are increasingly deployed to reduce environmental impacts of power generation, and their growing penetration is expected to affect power system dynamics through interactions with conventional generators and loads. The study aims to develop a variable‑speed wind turbine model that can be integrated into power system simulation tools. The authors present a comprehensive modeling framework that describes all variable‑speed turbine subsystems and outlines the approach for integrating it into dynamic simulation software. When implemented in PSS/E, the model’s simulated responses closely match measured data, demonstrating its validity for power system studies.

Abstract

A tendency to erect ever more wind turbines can be observed in order to reduce the environmental consequences of electric power generation. As a result of this, in the near future, wind turbines may start to influence the behavior of electric power systems by interacting with conventional generation and loads. Therefore, wind turbine models that can be integrated into power system simulation software are needed. In this contribution, a model that can be used to represent all types of variable speed wind turbines in power system dynamics simulations is presented. First, the modeling approach is commented upon and models of the subsystems of which a variable speed wind turbine consists are discussed. Then, some results obtained after incorporation of the model in PSS/E, a widely used power system dynamics simulation software package, are presented and compared with measurements.
