How power imported or exported using grids between two or more state??

there is a single grid system throughout the country.. if one state has more power it supplies others through a grid., if the same state is deficient of power it gets power from others by SAME GRID., how is this possible?? wats the principle??

the principle is ohm's law.

you might read the thread on alternators started by Bassalisk.

Synchronous machines connected in parallel are mechanically coupled by the grid, just as a team of horses is coupled by their harness equipment (is tack correct word?) .
