Software modeling systems for metering and translating measurements

摘要

Systems and methods are provided for collecting and aggregating a plurality of power flow measurements from a plurality of devices in a power management system. The error bounds of the aggregated power flow measurement are then determined using at least one error model. Systems and methods are also provided for inferring AC power flows from DC power flows. A device having at least one DC power flow sensor is augmented with at least one AC power flow sensor AC and DC power flows through the device are measured using the sensors over a range of operating points. An inference model of AC power flow in the device as a function of DC power flow is then built, wherein the error of the model is bounded. DC power flow through the device and in similar devices can then be then measured and used to infer AC power flow for the device.

1. A method comprising:
receiving, over a network, a plurality of power flow measurements from each of a plurality of devices, each device being associated with a power flow, each of the devices being capable of measuring the respective device's power flow within a measurement error; aggregating, using at least one computing device, the plurality of power flow measurements, producing an aggregated power flow measurement; determining, using at least one computing device, error bounds of the aggregated power flow measurement using at least one error model; wherein the plurality of devices comprises at least two sets of devices, each set of devices comprising at least one device of the same type and being described by a device error model, wherein the error bounds are computed as a weighted average of the error models of the respective set of devices where the weight is the percentage of total power measured by the respective set of devices.
