The Impact of Large Wind Farms on the Transient Voltage Stability Using Different Control Techniques-Jordan as a Case Study

In this paper, an overview of the major problems caused by connecting wind farms to conventional electrical networks is given. Then, the characteristics and impact of doubly-fed induction wind generators on the voltage stability of the network are discussed. This work is applied to the electrical grid in Jordan as a case study, using a detailed 40-BUS network model to represent the southern part of the Jordanian transmission system. This model is employed as a tool to study the system stability by illustrating the network response to a three-phase fault applied to the wind farm connection bus. The Electrical Transient and Analysis Program is used to perform various simulation cases of operational techniques of voltage and reactive power control. The study is done for different production levels of wind plants to achieve the goal of voltage stability assessment and to investigate the size of the system portion, which the introduction of the wind farm might correctly enhance. Finally, the current work reveals that with adequate reactive power support and a proper application of voltage control, the wind farm's performance during the fault can approach the same level as that of the conventional one.
