Storage and Renewables
• Acts to Stabilize Power Variations• For grid-tied applications, Can
Provide Transmission Congestion Relief– At the Generation Site
– At the Distribution Point
• Allows Dispatch of Renewable Power– Off grid applications
– On grid applications
44
Emerging Applications
• T&D Upgrade Deferral• Transmission Congestion Relief • Peak Shaving• Micro-Grid Systems• Energy Price Arbitrage• Remote Area Power Systems
55
Power vs. Energy Applications
• Capacity Issues– High Power/Low Energy
– Low Power/High Energy
• Operational Limitations– Discharge
– Recharge
