Voltage stability in weak connection wind farms

The total operating wind power capacity in the world increases fast, and these types of generating units also bring new opportunities and problems to the utilities and customers. It becomes necessary and important to evaluate their impact on the electrical network voltage stability, especially for weak connected systems. This paper uses the detailed wind energy conversion system and the full order induction generator model to analyze the voltage stability in a weak connection wind farm. The possibility of network voltage drop and instability are investigated by the detailed electromagnetic transient simulation program. Some techniques to improve the transient response of voltage are also discussed.
