Conclusions
The main goals of the smart grid are to upgrade the power grid, and so to make it more stable, reliable and efficient. But next to this there is another main goals, that is to make it possible and ready for the new technologies to be integrated in the various systems of the power grid.
Smart grid, the communications network for the electrical grid, has a great potential to improve the power grid in terms of economic and energy efficiency for the complex requirements in the field of power generation, transmission, distribution and supply. The power markets of many countries has undergone fundamental changes in recent years that makes it necessary to fall back on the use of ICT, more communication technologies, and more automation.
