Thanks Omar for sharing the articles, but I need very precise definitions.

Smart grid provides two way communication between utility and customers. Automation like AGC does not provide this feature. I feel that is the basic difference. For further information you may use this link.

Thank you for Krishnarayalu Movva your comment. In fact, the automation includes much more advanced operation and remote control facilities that are already available in the traditional grids. For example, remote wide area monitor, and load shedding schemes. IMHO, most traditional grids are already smart in the generation and transmission subsystems, or at least within the generation subsystem. The main problem is associated with lack of sufficient remote monitoring, energy management, and control within the subtransmission, and distribution subsystems considering distributed generation. If these facilities are integrated within these subsystems, then the entire system will be at the smart grid automation level. I am still confused between automation, and smart grids. It seems to me that they are the same if they are available allover the power system!

The automation concerns the automatic management of the power system that takes place by means of remote-controlled or programmed devices to respond to planned actions. The concept of smart grid is broader and incorporates all the technologies and functionalities that make the electricity system similar to the Internet: exchange of information not only for the management of the electricity system, therefore to automate processes, but also to simply inform users (who can also be customers) on the state of the system. In short, automation concerns the industrial management of the system (field level), when we speak of smart grid we also refer to the processing of information at a higher hierarchical level.

OK, I would say that a smart grid is a slightly extended form of s fully automated grid. In addition, the current structure of utility scale grids is partially automated and also partially smart. Anyway, the terms may be mixed if utility scale or large scale systems are considered, while the significant differences in the scope appear in micro grid scale.

I also tend to consider a smart grid as a commercial name of a fully automated grid regardless of its size.

What i believe "Automation is the part of smart grid". What, if there is automation without demand side management ?? So, we can move to complete automation grid system but not a perfect smart grid. Always there will be something to add.

Power system automation has existed for decades, gettitng cheaper all the time, is one of the enabling technologies used to make a smart grid work. Smart Grid is a term that arrived after the invention of the smart phone.

There are lots of articles about the "Smart" = automation aspect. It worries me sometimes that many people (especially politicians and business people) forget that the physical grid will need investment to use the benefits of all these new smart ideas.

With the Smart Grid infrastructure, the power system automation can be implemented very efficiently.

So smart grid technology can be used for many power system applications, and power system automation is one of it.

Power system automation is more general. It includes smart grids and traditional power system auxiliary services such as upgraded controllers of power plants, distribution systems automation and automatic generation control.

I think this is a matter of definitions, nothing more. Some arbitrary degree of automation may be accepted to name the system a smart one.

I agree with you Prof. Taher. Your comment is also in confirmation with the most of us.
