Smart Grid: distributed generation; Bi-directional information & powerflow; sensors.
The Smart Grid is an electrical grid which includes a variety of operation and energy measures, including smart meters, smart appliances, renewable energy resources and energy efficient resources.
Smart Grid

Many small energy generation and storage facilities are orchestrated using advanced information and communication technologies (ICT).
Energy visionaries imagine a 'self-healing' grid with real-time sensors and 'plug and play' software that can allow scattered generators or energy-storage devices to attach to it. In other words, an energy internet.
