  • Patent number: 10457159
    Abstract: A system comprises a plurality of power converters, a plurality of energy storage systems, a first common node, a second common node, and zero-reference voltage node. Each power converter is coupled between one energy storage system and the first and second common nodes. The system operates to regulate power between the power converters and the first and second common nodes. Each power converter is a bi-directional power converter and each energy storage system is a battery pack. In one example, the first common node is regulated to a voltage VSPAN, and the second common node is regulated to a voltage VSCN which is the mean of all voltages output by the battery packs. In another example, the first common node is regulated to a voltage ?VSPAN, and the second common node is regulated to a voltage +VSPAN. No power converter processes more than voltage VSPAN yielding high-efficiency power conversion.

The distributed DC-power includes one or more DC-voltages. Batteries can be temporarily switched into a power supply circuit to supplement the power supply during spikes in power load demand while a controller reconfigures power supplies to meet the new demand. One or more DC-to-AC converters handle legacy power loads. The DC-to-AC converters are modular and are paralleled for redundancy. The DC-to-AC converters are sourced from the one or more AC-to-DC converters. The AC power is synchronized for correct power flow control.

A hold time duration requirement for the power capacity is evaluated, where the hold time duration is a number of minutes. A number of allowable occurrences of power outage for the power capacity is evaluated. A power requirement metric, based on the outage time duration requirement, the hold time duration requirement, and the number of occurrences, is calculated. A power topology within the datacenter is modified based on the power requirement metric. The modifying provides dynamic power tiering within the datacenter.
