Abstract: A system enabling localized intelligent control with communication and coordination at local subsections of a power grid with information transfer to utility for supervisory control is disclosed. The disclosure extends the control and communication capability within, at the edge, and outside the edge of the power grid using intelligent and self-aware FACTS devices. Aspects of the disclosure enable control of a distribution network, energy storage systems and generation sources as an integrated system allowing optimization of power grid operation from generation to distribution. This control capability further enables a supervisory utility to implement and manage policy issues, such as standard compliance, carbon emission reduction, right-of-way management, and conformance to environmental regulations, such as EMI compliance, noise reduction, etc. This also allows the supervisory utility to optimize energy cost, network reliability, and asset utilization and life.

Abstract: A flexible alternating current transmission system (FACTS)-based shunt system is described for use in a hierarchy in a high-voltage or medium-voltage power grid. The shunt system includes a FACTS-based shunt device, a communication link, and a shunt controller. A hierarchy in the power grid includes a supervisory utility communicably coupled to localized intelligence centers (LINCs). Each LINC is communicably coupled to one or more impedance injection modules (IIMs) that are coupled to the power grid. The hierarchy has an optimization engine. The shunt controller, of the shunt system, is to communicate and cooperate with one or more of the LINCs in the hierarchy. The shunt controller is to operate the FACTS-based shunt device in accordance with such communication and cooperation with the LINCs, to provide voltage stability to the power grid through hierarchical control according to the supervisory utility, the LINCs and the optimization engine.

Abstract: A system architecture and method for enabling hierarchical intelligent control with appropriate-speed communication and coordination of control using intelligent distributed impedance/voltage injection modules, local intelligence centers, other actuator devices and miscellaneous FACTS coupled actuator devices is disclosed. Information transfer to a supervisory utility control is enabled for responding to integral power system disturbances, system modelling and optimization. By extending the control and communication capability to the edge of the HV power grid, control of the distribution network through FACTS based Demand response units is also enabled.

Abstract: Distributed static synchronous series compensators (DSSSCs) which may also be designated tower routers capable of injecting series inductive or capacitive impedances to enable distributed power-flow control. When a large number of these (a fleet of) DSSSCs are distributed over the grid for power-flow control, it is necessary to ensure that coordinated communication and control capabilities are also established, enabling fast reaction to changes that can exist across the grid. A system architecture and method for enabling localized high-speed low-latency intelligent control with communications between subsections (local network) of the grid along with communication to the central Grid operations center at the utility for supervisory control is disclosed herein.

Abstract: A device for use in a power transmission system to sense GICs. The device may be a part of a reactance-injecting device on a power line, it may be a standalone device, or it may be a part of another type of device. The device may include a sensor to sense magnetic fields (e.g., a Hall effect sensor). The sensor may be positioned in the air gap of a magnetic core formed concentrically around the power line. The signal from the sensor may be converted to a digital signal and separately processed to determine the magnitude of the AC current and the magnitude of the DC (or quasi-DC) current. If the output signal of another NC current sensor is available, that output signal may be used to adjust/calibrate the determined magnitude of the DC current. The sensor may communicate with other devices in a network to provide GIC information.

Abstract: Dynamic source balancing methods and systems are provided. Power may be provided to a user from one or multiple energy sources. At any time point, the multiple energy sources may have different LMPs and power flow among the energy sources may be controlled such that a user's energy costs are reduced or minimized. Energy arbitrage may be realized for a user by taking into account of various factors related to the energy sources, the power grid, the power market, and/or the user.
