Why DESS is needed ? • In “Grid 2030 Vision” report, Department of Energy has identified two of the top five concerns for the future smart grid: – Distributed Energy Storage System(DESS) – Distributed Intelligence and Smart Control(DISC)

• DESS application is very flexible: – Generation system: spinning reserve, firm up intermittent renewable energy sources – Transmission system: support load carrying capacity and stability, support voltage dip, peak shaving – Distribution system: peak shaving, power quality improvement; dynamic islanding
