1. A high-voltage power grid comprising:

  • a plurality of impedance injection modules coupled to a high-voltage transmission line at a number of locations in the high-voltage power grid, each impedance injection module having;

    a controller that senses disturbances and/or other conditions on the high-voltage transmission line of the high-voltage power grid and reacts by generating and injecting inductive and/or capacitive impedances of appropriate magnitude onto the high-voltage transmission line via an injection transformer coupled to one of the high-voltage transmission lines;

    a transceiver for high-speed communication with other impedance injection modules within a local group of impedance injection modules to enable coordinated response of the other impedance injection modules within the respective local group of impedance injection modules to disturbances on the high-voltage transmission line;

    the high-voltage power grid being further comprised of a group of local centers, each local center within the group of local centers having a high-speed transceiver for high-speed communication with impedance injection modules within a respective local group of impedance injection modules and with other local centers to enable coordinated response of all impedance injection modules associated with that group of local centers;

    wherein each local center includes a communication link to and from a system utility, the communication link to and from a system utility being for communication at a lower speed than the high-speed communication between impedance injection modules and between impedance injection modules and local centers.
