Devices and methods for decentralized power factor control
First Claim
1. A first controller configured to provide decentralized coordinated control over a first segment of an electrical distribution system supplied by a first substation while a second controller is providing decentralized coordinated control over a second segment of the electrical distribution system supplied by a second substation, the first controller comprising:
- a network interface configured to receive first measurements associated with the first segment of the electrical distribution system supplied by the first substation and transmit a control signal configured to control equipment of the first segment of the electrical distribution system, wherein the first controller is configured not to control equipment of the second segment of the electrical distribution system supplied by the second substation that is controlled by the second controller; and
data processing circuitry configured to run first digital simulations of the first segment of the electrical distribution system simulating various equipment configurations based at least in part on the first measurements, to select from among the various equipment configurations an equipment configuration that is expected to cause a power factor on the first segment of the electrical distribution system to approach a desired value, and generate the control signal, wherein the control signal is configured to cause the equipment of the first segment of the electrical distribution system to conform to the equipment configuration but not to control equipment of the second segment.

Abstract
Devices and methods for the decentralized, coordinated control of the power factor on 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 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 power factor 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 and thereby control the power factor.
