Towards a Smart Grid Communication

Smart grids are one of the technological answers to the ‘3 x 20’ objective of the 2020 climate and energy package of the European Union: 20% renewable energies, saving energy and reducing emissions green house gas. The effective insertion of the production of renewables of intermittent nature (wind and) photovoltaic) and new uses of electricity (heat pumps, electric vehicles...) in the electric system requires the design of equipment “smart’, thanks to the new technologies of information and communication. [1,2, 5)].A major challenge is to be able to use five key technology area :Integrated Communications, sensing and measuring,advanced components, advanced control methods, improved Interfaces and decision support in an industrial context demanding in terms of quality, safety, security and cost.This paves the way for researchers to propose relevant and sustainable solutions.This paper tries to focuss on the importance of Information and Communication Technology (ICT), which ensures a two way communications with a collection of secure and reliable data from sensors and meters located throughout the grid and transmitted directly to the grid operator's control room.
