Abstract
A high-voltage energy storage system (ESS) device is coupled to a feed from a utility power source to a transformer that steps down high-voltage power and feeds one or more loads in a data center. The high-voltage ESS device can store electrical power from the utility power source and discharge stored electrical power. An energy control system monitors waveforms associated with utility power sources and determines whether a waveform indicates a potential loss of electrical power. The energy control system also monitors costs of receiving electrical power from utility power sources and determines whether the costs associated with receiving utility power from particular utility power sources exceed one or more thresholds. The energy control system can command a switching device assembly to selectively route high-voltage power from a utility power source or from the high-voltage ESS device to the transformer based on a waveform determination or a cost reduction determination.
