Steps to smart grid realization

In principle, the smart grid is a simple upgrade of 20th century power grids which generally "broadcast" power from a few central power generators to a large number of users to instead be capable of routing power in more optimal ways to respond to a very wide range of conditions. In this paper we introduce four essential steps for implementation of a smart grid and explain about various solutions and technologies. At the end one optimum solution is concluded depending to the case.
