Smart grids: electrical networks that evolve in response to usage

Increasingly, we've heard of smart grids. But, what are they really and how do they change our way of consuming electricity?

The use of electricity has changed greatly since its early days: from simple wireless receivers on to household appliances, heating systems, flat screens, and today’s electric cars, electrical devices have proliferated and our energy needs have increased

At the same time, it is necessary to integrate more and more new means to generate energy such as solar farms and wind parks, whose renewable energies can also be produced by consumers (factories, buildings, individual homes, etc…).

The power grid needs to become smart to adapt to these changes. Equipped with state-of-the-art analytical, diagnostic, communication and real-time monitoring devices, power grids must exchange data, enabling the accountability of the actions of all stakeholders and thus ensuring a balance between supply and demand as well such as predicting discontinuous falls in the generation of renewable energy, etc. In short, power grids are capable of remotely manage and direct the most efficiently flows of electricity generated and consumed.

Smart Grids: Consuming Electricity Intellingently

Smart grids, through their connection with smart meters, allow fine control over electricity consumption by detecting events such as a surge due to excessive generation and by delaying or interrupting the operation of certain devices. Consumers are informed in real time about their consumption level and encouraged to manage it better. They may be invited to turn off certain devices during peak consumption periods or be informed by management tools of the most favorable times (technically and economically) to recharge electric car batteries.

And smart metering?
Smart meters are components in smart grids. They measure electricity, water, and gas consumption, as well as light emissions and data from presence detectors…. This information is then used to assess the energy performance of a building and to implement precise adjustments to respond to immediate conditions or to use as long-term settings.
