How Bi-directional Power Flow can be achieved in Smart Grids??????
Hi Mukhtiar. Let me give you a simple example. EVs will be one of the most important components of the future smart grids. During EV charging, the power will be transmitted from the grid to the battery system. However, in some occasions, it is possible to fed back power from the EV storage to the utility grid, e.g. for frequency regulation. Here, a two directional energy path can be established. Similarly, other sections of smart grid may also have such capability. the following pdf can give u a good understanding for realization of bidirectional energy flow.
In any smart grid in which you have PV, Fuel cells sources or small biogas power plants and of course EV you will have bidirectional power flows, even it is radial and connected to other parts of utility or distribution grid. Farshid Naseri shaw the sample case,
Dear Mukhtiar,
You can have a look of our paper I am enclosing it for you.

Power can flow bi bidirectionally in the grid. What you might want to know is how can we keep reliability of grid intact under this operation. And solutions provided are different for different phenomenon like protection, voltage control etc.
Bi-Directional power flow in smart grid systems is possible by implementing the distributed energy generation sources using the renewable energy sources like wind & solar etc. according to their availability. during the peak load hours power from the grid will be imported by the consumer to meet his load demand and during off Peak hours the consumer will export the power from his premises to the connected grid.
