Traditional grid structure Future grid structure
• Customers receive electricity
• Dedicated networks with limited resources
• Grid as a sole source
• Real-time data/control
• Customers receive/feed electricity
• Networks with shared assets and layered customer resources
• Grid as a sole source, back-up, and two-way flow
• Increased real-time data/control
