Within electricity grid networks it is conventional for large-scale central generators to both provide power and control grid node voltage. Therefore when wind turbines replace conventional power stations on a substantial scale, they must not only generate power, but also control grid node voltages. This paper reviews the basic principles of voltage control for tutorial benefit and then considers application of grid-connected wind turbines for voltage control. The most widely used contemporary wind turbine types are considered and further detail is given for determining the range of variables that allow control.
