    Abstract: A system for performing computing operations in a data center includes one or more sets of computer systems, one or more primary power systems, and a reserve power system. The primary power systems include a downstream portion that supplies power to at least one of the sets of computer systems. The reserve power system includes switches that switch between supplying a primary power feed and a reserve power feed from the reserve power system through part of the primary power system. An input resiliency switch can switch between supplying primary power or reserve power to support power supplied to the sets of computer systems through the primary power system based upon a primary power feed fault. A power distribution switch can switch between supplying primary power and reserve power to part of the downstream portion of the primary power system to bypass an upstream portion of the primary power system.

    Abstract: Managing power feeds includes monitoring a waveform of a high-voltage power feed supplied to an electrical load to detect potential interruption of the high-voltage power feed and switching to another power feed to supply power to the electrical load in response to identifying the waveform pattern. Monitoring a waveform includes processing the waveform to determine if one or more waveform patterns are present in the waveform. A waveform pattern indicates, by its presence in a waveform of a power feed, a power event associated with the power feed, and some waveform patterns indicate potential interruption of the power feed. Switching to another power feed in response to determining potential interruption of the power feed based on waveform monitoring enables an uninterrupted power supply.

    Abstract: Techniques for detecting a cause or a location associated with a power disturbance affecting a power distribution system are described. For example, an indication of such a power disturbance may be received from a power meter of the power distribution system. Power-related data may also be received from another power meter of the power distribution system based on the indication of the power disturbance. A cause or a location associated with the power disturbance may be determined based on the power-related data received from the other power meter.

    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.

    Abstract: An energy storage system (ESS) provides redundant power feed support to a power system which provides secondary power support to a set of electrical loads, independently of a power system which provides primary power support. The power inlet connection of the power system can be switched between a utility power feed and a discharge feed from the ESS based on determinations regarding whether the utility feed is interrupted. The ESS and the power system can each be coupled to the utility power feed via separate breaker-supported power line connections, which themselves can be coupled via a breaker-supported branch circuit downstream of the power line connection breakers. The branch circuit breaker can be closed, to switch the power inlet connection from the utility power feed to the ESS, based at least in part upon a determination of a voltage difference across the branch circuit breaker.

    Abstract: Techniques are described for providing an automatic transfer switch (ATS), such as in a data center, to determine whether the power system coupled to a first power input on the ATS is the same power system or a different power system that is coupled to a second power input on the ATS. The ATS determines and compares the electrical characteristics (e.g., voltage, current harmonics, etc.) to determine if there is a difference between the determined characteristics. If the electrical characteristics are substantially similar, then a single power system is coupled to both power inputs on the ATS. But if the electrical characteristics are significantly different (e.g., the difference in the electrical characteristics is above a threshold), the power system coupled to one power input on the ATS is different from the power system coupled to the other power input on the ATS.
