Vision of a Smart Grid
The Smart Grid will:• Enable active participation by consumers• Accommodate all generation & storage options• Enable new products, services & markets• Provide power quality for the digital economy
• Optimize asset utilization and operate efficiently• Anticipate & respond to system disturbances
(self-heal)• Operate resiliently against attack & natural
disaster
