Smart Grids: Reasons and Origins
Growing energy demand
Integration of more renewables, electric vehicles and energy
efficiency
Ambitious climatic goals
The energy demand, combined with ambitious climatic goals, as well as with the integration of more renewables and the electric vehicle,
push for increased flexibility of the electric power network

Power Network Management is evolving from a traditional concentrated generation configuration
into a phase of high penetration of Dispersed Generation, Renewable Energy Sources, and Energy Storage, which will require an Active Management of
the Smart Grid

Power Networks are changing into a
complex and interconnected grid, a mix of transmission,
distribution and dispersed generation, which will provide the citizens with a reliable,
efficient and environment friendly
power supply.
