Abstract
Techniques for controlling an energy storage device to reduce peak power demand at a site are provided. In one embodiment, instantaneous power usage at the site can be monitored, where the instantaneous power usage corresponds to power that is instantaneously imported or exported at a point of common coupling (PCC) between the site and a utility-managed energy grid. A historical power usage value for the site can then be calculated based on the monitored instantaneous power usage, and the historical power usage value can be compared with a target peak value plus a buffer value. If the historical power usage value exceeds the target peak value plus the buffer value, the target peak value can be set to the historical power usage value.
