Abstract: The invention provides a method and system for operating a solar farm inverter as a Flexible AC Transmission System (FACTS) device—a STATCOM—for voltage control. The solar farm inverter can provide voltage regulation, damping enhancement, stability improvement and other benefits provided by FACTS devices. In one embodiment, the solar farm operating as a STATCOM at night is employed to increase the connectivity of neighboring wind farms that produce peak power at night due to high winds, but are unable to connect due to voltage regulation issues. The present invention can also operate during the day because there remains inverter capacity after real power export by the solar farm. Additional auxiliary controllers are incorporated in the solar farm inverter to enhance damping and stability, and provide other benefits provided by FACTS devices.

Abstract: Generally, systems, devices, and methods for a generalized architecture for power and networking in robotic systems is presented. On a robotic chassis, a branching cable harness routes multiple power connections and communications interfaces from an onboard computer and multiple power supplies to various locations on the chassis. Each branch carries all the power and communications connections that are needed by various peripherals, and all the branches terminate with identical connectors. A custom patch cable for each peripheral, such as a camera, taps the appropriate power and communications interfaces from the branches for the peripheral. The peripherals can be relocated on the chassis by unplugging their respective patch cables from the central cable, relocating, and then plugged the patch cables into the nearest branch.
