The Big Data gathers the massive and varied data, retrieved in real time from the Internet, which is then processed, stored and exploited. But did you know that it is also one of the pillars on which the energy transition ? Some energy players are also using this data to improve their service. Here’s how these mega-data improve and optimize the power consumption.
Intelligent buildings that save money
The digital conversion The current situation benefits the ecological transition. And we have proof of this with the home automation. This includes all the electrical systems that allow, locally or remotely, to control and automate the equipment of the dwelling allowing at the same time to improve its comfort, but also tooptimize its energy consumption.
Indeed, these connected buildings rely on smart power grids – the smart grids – present in the public distribution network, to store and send data concerning the condition and use of the building. In this way, they allow the unused electricity to be fed back into the grid and thereby improve the power draw of the networked house.
These intelligent habitats rely on these same technologies to intermittently integrate renewables in the distribution network. Indeed, the latter is made more reactive and can anticipate variations in production from renewable sourcesand thus, flexibly, facilitate the insertion of green energy into the network.
They also integrate sensors distributed in strategic locations in the home to control, among other things, lighting, heating system or household appliances and, therefore, toadjust energy consumption.
Solar home automation to optimize self-consumption
The New Information and Communication Technologies (NICT) also allow the integration of this inexhaustible but intermittent resource, which is thesolar power. In the event that photovoltaic solar panels installed on the roof of the house are directly associated with a home automation system, we then speak of a “home automation system”. solar home automation.
The objective is to improve thesolar self-consumption of the building, i.e. the building consumes as much of its own energy as possible. power generationa electricity produced by its solar plant. By relying on connected devicesit is possible to make operate electrical appliances mainly when the sun is shining.
Linky Smart Meters
Let’s take a look at one home automation device in particular: the Linky counter. It is expected to be present in all homes by 2021.
This connected box collects data remotely and initially allows the power grid operator to Enedis to better control the energy demand of the buildings it serves and to better control the energy demand of the buildings it servesthus avoid problems of overproduction.
On the individual side, they can have access to their Linky data by connecting to their personal space on the Enedis website. Because this data is accessible almost in real time (viewable the next day), it is possible to adapt electricity consumption, and thus reduce it, because it is possible to :
- scale back by taking note of the eco-gestures delivered by the Agency for Ecological Transition (ADEME) ;
- switch power suppliers if it offers both green energy and lower rates;
- identify dysfunctionsand therefore abnormal consumption, taking as a point of comparison the consumption of dwellings with similar characteristics to avoid energy loss.
Finally, this connected meter favours thesolar self-consumption. When connected to solar panelsIt promotes the consumption of during the periods when photovoltaic panels are most efficient.
There are still outstanding issues regarding larger scale projects, including the use of data from the smarts cities – smart cities – throughalgorithms and artificial intelligence (IA). It is to be hoped that local and regional authorities will take up technologies such as theInternet of Things (IoT), or systems of data.
But it is certain that the place of digital technologies in the battle against the climatic upsetwith the objectives of reduce greenhouse gas emissions emissions by at least 50% by 2030 compared to 1990 levels and to achieve carbon neutrality by 2050, is unquestionable.
