PureWave - Model CES -Community Energy Storage System

Offering 25 kW for one or two hours, PureWave CES has enough capacity to supply power to a group of customers for the duration of most typical outages. Deployment of these units on a broad scale will significantly improve your customer minutes served — an important index of grid reliability — while greatly reducing your emergency dispatch costs. With its ability to utilize buried distributed batteries, the PureWave CES provides a small footprint that does not change as the energy storage is scaled.

PureWave CES Design Features

• Maintenance-free power electronics comply with IEEE 1547 and UL 1741
• SCADA radio control
• Real-time analog/digital input/output
• Hard-wired bypass available for installation and maintenance
• Status and control panel

Reliability Benefits

Customer Friendly

• Supports multiple customers for hours
• Momentary outage is barely perceptible
• Customers are isolated from repeated operations and transients
• Seamless return-to-normal
• Customers experience “premium” power

System Friendly

• Reduced SAIDI. Power is maintained to customers
• Reduced MAIFI/SAIFI. Customers experience one or zero operations
• After an interruption, system experiences reduced load, reduced inrush
• System can be set for staged return, reducing cold load pickup

IntelliTeam DEM Distributed Energy Management System resides in the substation or control room, and acts as a “master controller” of CES units. It constantly checks the status of each CES unit and presents a summary view to the Distribution Control Room. IntelliTeam DEM can command groups or fleets of CES units, allowing their output to be coordinated to perform higher-level functions such as:

• Peak shaving/load leveling
• Fleet charge/discharge
• System-level real or reactive power request
• Renewable energy time shift
