International Classification:

G06F 19/00
G01R 21/06

US Classification:

702 60

Abstract:

A system for enhancing deferrable load management of a distribution transformer includes a memory device configured to store a plurality of operational measurements of a distribution transformer and at least one deferrable load. The system also includes a processor coupled in communication with the memory device. The processor is programmed to record a first operational measurement of the distribution transformer that is configured to transmit electric power to the at least one deferrable load. The processor is also programmed to record a second operational measurement of the at least one deferrable load. The processor is further programmed to determine a priority of energization of the at least one deferrable load within a queue as a function of at least one of the first operational measurement and the second operational measurement.

International Classification:

G06F 1/30
H02J 3/16

US Classification:

700293, 307109

Abstract:

A system for controlling voltage on a distribution feeder includes a plurality of capacitor banks that can be connected to or disconnected from the distribution feeder. A first bank is configured to connect to the distribution feeder when a first voltage is below a first lower threshold value and to connect to the distribution feeder when the first voltage is above a first upper threshold value. The first upper threshold and first lower threshold are determined based off an operational set point. The system further includes a sensor configured to measure the first voltage and a controller in operable communication with the plurality of capacitor banks configured to determine the operational state of the first and second capacitor banks and, based on the first voltage, send a first instruction to the first capacitor bank, the first instruction causing the capacitor bank to vary the operational set point.

International Classification:

G05D 11/00

US Classification:

700286

Abstract:

Devices and methods for the decentralized, coordinated control of the active power losses of an electrical distribution system are provided. For example, a controller may include a network interface and data processing circuitry. The network interface may receive first measurements associated with a segment of an electrical distribution system and transmit a control signal configured to control equipment of the segment of the electrical distribution system. The data processing circuitry may run digital simulations of the segment of the electrical distribution system in various equipment configurations, selecting from among the various equipment configurations an equipment configuration that is expected to cause the active power losses of the segment to approach a desired value. The data processing circuitry then may generate the control signal, which may cause the equipment of the segment of the electrical distribution system to conform to the equipment configuration.
