How can a generator improve power factor

I have heard in a lecture that, if four generators are supplying a load, and the power factor happens to be poor. It is more convenient to improve the power factor by making one of the generator operating as a reactor or motor-I'm not sure-. Hence, I want to ask is that possible ?
and how is it done??

Hi: The best way to improve power factor (usually lagging with an inductive load) is by the addition of capacitance. Looking at power line poles you will occasionally see a group of rectangular boxes mounted high in the pole. These are capacitors being used for power factor correction. Another method is to use something that is called a synchronous condenser. This is a large synchronous motor placed on line with no load used to improve power factor. Changing the field excitation will allow a range of output either leading or lagging. Theoretically, it is possible to use one of the generators to aid in power factor correction. My day of having the theory at my finger tips is long gone. But as with other information, I am certain you could find an explanation with more detail on the internet.
