Purewave energy storageWith the increase in wind, concentrated solar, and other renewable energy sources in the overall generation mix, it’s essential that these variable sources be made more dispatchable, so that more renewable energy is available to the grid. One way to accomplish this goal is to store the energy during off-peak demand times, and then discharge the energy into the grid during peak demand times.

PureWave Storage Management System offers megawatt-hours of energy storage for Smart Grid applications, permitting this power to be dispatched when it’s needed. Power generated off-peak can be used during periods of peak usage, dramatically reducing the greenhouse gases produced by traditional generating sources, and displacing peak energy costs with off-peak costs.

The flexible interface allows for individually-controlled multiples of 500kW, up to a maximum of 10MW. Some applications for which the PureWave SMS can be used:

  • Peak shaving/load management
  • Load following
  • Renewable generation smoothing & dispatch
  • Islanding
  • Frequency regulation/grid stabilization
  • Facility power protection (UPS)
  • Voltage/power factor regulation

Applications

PureWave SMS for Renewable Energy. Solar and wind energy are intermittent power sources that the grid must accept whenever available. During absences of sun or wind — when these sources are not generating — replacement power must be provided. The PureWave SMS can store the power when it’s produced, and then use that energy for generation ramp-rate control, output-smoothing, or time-shifting.

Grid-Scale Energy Storage. The PureWave SMS can deliver up to 2 MW of stored energy to the grid from any type of battery storage system.

Islanding. When applied with S&C’s IntelliTeam® SG Automatic Restoration System, the PureWave SMS can be used in remote areas, as an energy source during power outages. Upon loss of utility power, IntelliTeam SG re-configures the distribution system and uses the stored energy to serve local customers — now isolated from the utility — for as long as 7 hours.

Peak Shaving. During high demand periods, the PureWave SMS can provide full output for up to 7 hours. This reduces the system peak, deferring the need for capacity additions on the distribution or transmission system.
