Abstract: Embodiments of the present invention produce and define a relationship between local voltage and power measurements at a node of an electrical network and system conditions on a remote branch of the network. These local measurements are used to determine an optimal voltage set point at the node that, if realized by a reactive power resource, would affect the flow of reactive power or line current at one or more particular remote branches of the power system in a manner captured by the derived relationship. The change in reactive power required to obtain this voltage set point is also calculated based on local measurements.

Abstract: Energy management methods and systems based on financial impact are disclosed herein, wherein an energy management system at a site monitors metered energy consumption, establishes a peak consumption level, determines whether energy consumption will result in an increased peak consumption level, and if it will, calculates the financial value and costs of mitigating an increase in the peak consumption level, including an increase in demand charge prospectively avoided, and mitigates the peak in consumption to the peak consumption level using an energy storage system or other energy providing device if the value of mitigating the peak offsets the inherent costs. Embodiments may further use confidence factors or incremental changes to a peak consumption level to optimize the process and utilize energy devices to their greatest effectiveness.
Abstract: Described is a method of generating a flow having a composition gradient. A plurality of pump strokes is generated for each pump in a plurality of pumps. Each pump stroke has an initiation time and provides a volume contribution of a liquid to be mixed in the flow according to the composition gradient for the flow. The pump strokes of the pumps are controlled so that a sum of the volume contributions of the liquids that occurs between consecutive initiations of one of the pumps is maintained at a constant value throughout the duration of the flow. For each pump, the flow rates and the times between stroke initiations can change as long as the sum of all volumes contributed between the consecutive initiations of one of the pumps is held constant. Advantageously, the method achieves a constant compositional noise characteristic throughout the duration of the flow.

Abstract: A data center energy management (DCEM) server configures a power supply in the data center. The DCEM server sums input alternating current (AC) power of the power supply to a total AC power of the data center, wherein the total AC power of the data center is a sum of AC power of a plurality of power supplies. The DCEM server sums output direct current (DC) power of the power supply to a total DC power of the data center and reports a ratio of total AC power to total DC power as data center power conversion efficiency. The DCEM server sets a preset power supply efficiency threshold. The DCEM server determines that a real-time power efficiency level is below the power supply efficiency threshold. The DCEM server, responsive to a determination that real-time power efficiency level is below the power supply efficiency threshold, may remedy the power supply.
