Smart Grids: The Concept

Strong development of renewable energy resources, environmental sustainability and CO2 emission reduction

Promote technological upgrade or assets investment deferral

Enhance efficiency in grid management and control using widespread monitoring and automation

Market liberalisation for multi-player participation

Bi-directional energy flows changing the traditional network operation mode

Controlled integration of distributed generation Assign an active role to the consumer/producer with micro-generation and demand response Distributed local LV network control
