Energy storage peak shaving of electrical power for facilities

摘要

A method of shaving peak power consumption by a facility includes determining a target peak demand setpoint for a facility and measuring power consumed by the facility. An electrical storage system (ESS) is charged when the measured power consumption is below the target peak demand setpoint. Additionally, the ESS is discharged and provides power to the facility when the measured power consumption is above the setpoint. Further, as data for the facility and ESS changes, the target peak demand setpoint is updated.
