Dynamic Computation and Heirarchical Control of Assets of a Power Grid Using Shunt and Series Connected FACTS Devices

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.
