Wind farm: Dynamic model and impact on a weak power system

Abstract

The inclusion of wind power in power systems is steadily increasing around the world. This incorporation is forcing the utilities to assess its influence on the dynamics of power systems. Therefore, it is important to evaluate the information resulting from models that simulate the dynamic interaction between wind farms and the power systems they are connected to. Such models allow performing the necessary preliminary studies before connecting wind farms to the grid. The purpose of this paper is to show by means of simulations the voltage fluctuations caused by a wind farm linked to a weak power system. A model for dynamic performance of wind farms is presented. Moreover, a wind speed model and a wind turbine model are briefly presented. The results of the effects of the wind farm on the grid performance are shown in a testing power system through different settings.
