As you reduce your demand to zero, the current falls to zero, then when you start feeding into the grid, the current becomes negative with respect to voltage (ie. 180 degrees out of phase). So to determine energy flow, you need to know the current in the wire and whether that current is negative or positive with respect to the voltage.
