How do power plants feed electricity into the power grids?

I understand the different methods that power companies use to generate electricity. What I was wondering about is how they transfer the electricity into the power grid. Do they feed it directly from the electricity generator to the grid or do they transfer it to a type of storage and then regulate the rate that if feeds in the power lines?

Also, I would really appreciate it if you could give me a link to a website that contains more information regarding this question.

Thanks

    There is no really good storage method for electric power.

    It is fed into the grid as it is generated, carefully. The voltage, frequency and phase has to be matched first. Then the voltage is increased, keeping phase matched, until current flows out of the plant at the rated capacity.

    Power is generated at a medium voltage level and then “stepped-up” to transfer power over large distances and then “stepped-down” so it can be utilized at the load location. It is hard to visualize but generators are coupled to the power grid so they are at a set speed with relation to the 60Hz frequency of the grid. Varying the torque fed into the generator from the turbine or motor is directly related to the real power watts fed into the grid. Varying the generator field excitation controls the reactive power or VARs fed to the grid.

    Directly to grid by synchronizing.
