Smart power grids

Power grids transport the electricity from the point of production to the point of consumption.

Power grids transport the electricity from the point of production to the point of consumption.
Consumption points.

The introduction of smart grids will mean modernising existing installations and adapting them to twenty- first century technology.
Adding digital technology to meters and distribution and control centres will:
• Make them more efficient
• Limit energy losses
• Cut carbon emissions
• Better quality of supply

The greatest advantage of the new smart grids is the detailed information they provide. This is very useful for:
• The general public. With more and more reliable information about their consumption habits, they can take the necessary energy saving measures.
• Creating new rates that better meet the real energy needs of citizens.
• The system. It will manage demand better and reduce the use of less efficient generation plants leading to lower emission rates.

Smart Grids provide information in two directions: to users and system managers. User consumption, energy produced in small facilities, failures at points in the grid. A large volume of information for a complex interconnected network.

ENERGY + INFORMATION
TWO-WAY INFORMATION

The most visible part of the new grids will be the SMART ELECTRICITY METERS.

• Remote readings: no more invoices with consumption estimates.
• Users will be able to check their consumption figures at all times using web applications.
• hey will be able to switch rates with immediate effect.

New services will be created with specific rates to adapt to different uses, etc.

The smart electricity meter sends information to and from the system managers: consumption, energy produced in small facilities, failures, etc.
Users can check real consumption at all times (doing away with the need for bills with consumption estimates), rate changes, etc.

Smart information and control systems will have to be installed.

The new smart grids will be capable of efficiently absorbing and monitoring supply from multiple small producers making the grid vastly more complex:
• Photovoltaic panels.
• Small CHP producers.
• Domestic micro-generators.
• Electric vehicle users.

Solar panels: connected to the digital grid, they supply power to the grid.

Digital gas meter
Digital water meter
The smart electricity meter can receive signals from digital gas and water meters and send it to the services managers, avoiding the needs for estimated readings.

The introduction of electric vehicles will also add new loads and complexity to the grid. A smart grid will be needed to provide the user with complete information on load, and to the system on occasional energy requirements.

Charging point.

Production centres will be increasingly diverse and will be available closer to the energy users thus cutting transmission losses and, by extension, carbon emissions.
