The Smart Grids concept

Historically, grids have been developed to transmit electricity from power stations to consumers. This paradigm tends to change with the massive integration of renewable energies leading to electricity circulation in two directions. The arrival of electric vehicles, representing a significative electrical load, will also impact the electric system. The deployment of Smart Grid technologies allows for the support of the energy transition.

A Smart Grid is a modernized electric grid relying on new communication and IT technologies allowing measurement, control, data management and remote action in order to better manage the entire electricity grid, from producer to the final consumers.

One of the first building blocks behind the electrical Smart Grid is the communicating smart meter known as ‘Linky.’ Linky allows, among other things, for the achievement of better visibility across the distribution grid.

A Smart Grid demonstrator is a project deployed in a limited geographical area (for example on tertiary and industrial sites) to carry out experiments on grid management schema and electrical uses. A demonstrator thus makes it possible to implement technological innovations on the real grid and to draw lessons from experiences to make decisions on the industrialization of certain innovations. It also makes it possible to develop business models and, if necessary, propose regulatory evolutions.

The aim of Smart Grids is to:

> Reduce greenhouse gas emission rates (CO2) in order to combat global warming.

> Foster the development of renewable energy and new electricity usages.

> Avoid costly reinforcement of the electricity grid by setting in place an intelligent energy management system.

> Allow customers to realize energy savings in order to make them players in their own energy consumption.

> Improve the reactivity of the grid in cases of consumption or production peaks (adjustment of supply and demand).
